Ninja Gaiden/Characters

The characters in Ninja Gaiden introduced during the NES trilogy and X Box Prequel series.

Many unmarked spoilers ahead: you've been warned.

A. Foster
"Debuting in: Ninja Gaiden (NES)"



One of the head honchos at the CIA's Secret Auxiliary Unit and Irene Lew's immediate boss, A. Foster is a corrupt CIA agent obsessed with power, demonic power in particular. He attempts to coerce Ryu Hayabusa to fetch the Demon Statues for him in the first NES game. Foster shows his manipulative, ungrateful side when he orders Irene to assassinate Ryu and bring the statues back to him; not getting what he wants and with Ryu still alive, Foster shows up again in the third NES game (second chronologically) The Ancient Ship of Doom, plotting his "Biohazard" plan. His goal is to create a race of super-beings, and is indirectly responsible for Irene's temporary death, which sets Ryu in full force against him. .

 * Evilutionary Biologist: Plans to use the dimensional energies to create a race of energy-infused superhuman mutants.
 * Frame Up: He creates a clone of Ryu and uses it to kill Irene..

 * The Unfought: Although some speculate he's the boss of the sixth level in The Ancient Ship of Doom in a mutated form, it's really Ryu's Bio-Noid clone because of the way it refers to Ryu as the original.

Ashtar
"Debuting in: Ninja Gaiden II: The Dark Sword of Chaos"



The main antagonist of the second NES game The Dark Sword of Chaos and a warlord, Ashtar is the self-proclaimed "Emperor of Darkness". Said to be both a skilled warrior and a powerful sorcerer, Ashtar is well over six feet tall, and dressed in bulky body armor. With a cape is draped over his shoulders, his face is concealed by his helmet which has three spiky horns protruding from the top and both sides of the head.

Foster's accomplice in The Ancient Ship of Doom, H.P. Clancy helped trigger many of the events during the game. Clancy built the Castle Rock Fortress over the ruins of Jaquio's fallen temple, as he and Foster found a continuous supply of life energy within the ruins; Jaquio's downfall left traces of evil surrounding the site, thus the fortress was built to harvest the energy as a power source, and used it on humans for experiments. .

Irene Lew
"Voiced by: Amanda Troop (EN - Dead Or Alive Dimensions), Yumi Touma (JP - Original Video Animation, Dead Or Alive Dimensions)

Debuting in: Ninja Gaiden (NES)"



Heroine of the NES trilogy and Ryu's primary Love Interest for the whole series, Irene Lew is an agent of the CIA's Secret Auxiliary Unit, working under the codenames "Sea Swallow". Despite her status as an agent, Irene is more of a support for Ryu as she often finds herself captured and winds up being rescued by the Dragon Ninja. When she disregards Foster's orders to kill Ryu after defeating Jaquio, Irene starts to devote her life to Ryu. Sometime after the OVA, she marries Ryu and settles for running an antique shop, while aiding him from time to time during the Dead or Alive tournaments.


 * Action Girl: In the NES trilogy.
 * Action Girlfriend: Irene and Ryu were already an item in The Ancient Ship of Doom, and she has her moments in it.
 * Adaptation Dye Job: Originally a brunette in the NES trilogy and OVA, but is a blonde as of Dead Or Alive Dimensions.
 * Bare Your Midriff: Her appearance in Dead or Alive Dimensions, which is the only daring part of her attire now., Irene remains quite modest.
 * Chickification: Hit her hard in the OVA; in fact, she's not even a Faux Action Girl, but a Distressed Damsel from start to finish.
 * Distressed Damsel: At least once in each game she appears in, full stop in the OVA.
 * Eighties Hair: Her hair style in the NES trilogy.

 * You Don't Look Like You: As a result
 * Faux Action Girl: Even as a CIA agent, Irene isn't the most dependable ally.
 * Happily Married: With Ryu as of Dead or Alive; later games in the series try to make it ambiguous by only going as far as to state they're still together.
 * Informed Attribute: The fact Irene runs her "husband's" antique shop is only seen in a brief passage for the first Dead or Alive official guide that Tecmo released back then. This is only supported by the OVA, as Irene never actually appeared in Dead or Alive until Dimensions, and we don't see her taking care of the shop in it either.
 * Mission Control: For Ryu in Dead or Alive Dimensions.
 * Not Quite Dead:.
 * Ten Minute Retirement: The OVA shows Irene cutting all ties with the CIA. Dimensions, however, shows she still has at least some contact with the agency.

Jaquio
"Debuting in: Ninja Gaiden (NES)"



Main antagonist of the first NES game, the sorcerer Guardia de Mieux dubbed himself "Jaquio" (supposed to be "Jaki-Oh", as in "Devil King"). While supposedly human, Jaquio appears as a bizarre, uncanny magician with purple skin dressed in a red torn tunic with a hexagram embroidered on the front and a purple skeleton of a demon wrapped in his body like an armor. Jaquio as Chief of the Chaos Tribe, and he plans to steal the Demon Statue and break the seal on the Dark God, plunging the world into darkness.

Joe Hayabusa
"Voiced by: Norio Wakamoto (JP), Keone Young (EN)

Debuting in: Ninja Gaiden (NES)"



Known as Jô/Joe in Japan and "Ken" in North America for the NES series, he is Ryu's father, current leader of the Dragon Ninja Clan, and previous wielder of the Dragon Sword. Much like his son, Joe is a Master Ninja and in contrast to Ryu who trains for discipline and tradition, Joe seeks to surpass his limits. His preferred ninja attire of choice is a white shinobi shozoku (ninja uniform), although he's adorned with some armor around his body.

In the NES trilogy, Joe leaves Ryu with the Dragon Sword to engage in a duel (later revealed to be one of Jaquio's minions Bloody Malth). The outcome of the fight is not seen, but Joe winds up becoming controlled by Jaquio's magic. Ryu breaks the sorcerer's hold on his father and frees him. In the current series, Joe constantly leaves to continue his training, as Ryu states his father is "never satisfied with the power he wields". In Ninja Gaiden II, Joe fails to prevent Elizébet, Queen of the Greater Fiends, from taking the statue sealing the Archfiend, as he duels with Genshin, Overlord of the Black Spider Ninja Clan. Injured and blinded, he tasks his son to prevent the Archfiend from resurrecting.

Joe returns in Ninja Gaiden III.

Robert T. Sturgeon
"Voiced by: Norio Wakamoto (OVA), Zach Hanks (EN - Ninja Gaiden 3), Bin Shimada (JP - Ninja Gaiden 3)

Debuting in: Ninja Gaiden II: The Dark Sword of Chaos"



Also known as "Jungle Rat" Robert, he's a United States Army Special Forces operative who aids Ryu throughout The Dark Sword of Chaos, constantly revealing information about Ashtar. Although no different than a modern day commando, Robert proves himself useful to the Dragon Ninja, including being a reliable informer, following Ryu closely to the Tower of Lahja and surrounding the area with US Army forces to distracts Ashtar from finishing off Ryu. He proceeds to enter the Chaos World for the final battle, but Robert only goes as far against Ashtar,. While it seems he dies keeping the demons from reaching Ryu, the OVA reveals he survived, having quit the army and running a private eye agency to keep track of Ryu, but offering him any assistance the ninja might need in the future.


 * Armor Piercing Slap: Robert, a highly trained soldier, after completely raiding a building full of mutants with just his friend Jeff and later all by himself, gets slapped by Katherine shortly after he lives through it.
 * Badass: Robert proved himself in The Dark Sword of Chaos from start to finish, aiding Ryu on equal grounds, planning good barricades with the US Army, holding off fiends by himself.
 * Badass Normal: And of course, Robert is just a highly trained soldier.
 * Blood Knight: While a peaceful guy most of the time, Robert does a long speech in the OVA about how the battlefield for him is not much different than what most men desire.
 * The Cameo: Appears in Ninja Gaiden 3.
 * Cool Shades: Never takes them off.
 * Fire Forged Friends: With Ryu during The Dark Sword of Chaos, later with Jeff in the OVA.
 * Mysterious Watcher: Introduces himself as one, and has other minor moments as well.
 * One Man Army: Not to the extent of Ryu, but Robert sure knows his way within the Chaos World.
 * Private Detective: After quitting the army
 * Retired Badass: Not for a very long time, but still long enough.
 * Wacky Marriage Proposal: After killing dozens of mutants in a closed site with Jeff, adding a high chance of getting himself killed, when Robert lives through it, he proposes to Katherine seconds after in the OVA.

Ryu Hayabusa
"Voiced by: Hideyuki Hori (JP), Justin Gross (EN - Ninja Gaiden), Josh Keaton (EN - Ninja Gaiden II), Troy Baker (EN - Dead Or Alive Dimensions, Ninja Gaiden 3), Keiichi Nanba (JP - OVA)

Debuting in: Ninja Gaiden (Arcade)"



Protagonist of the series and heir to the Dragon Ninja Clan, Ryu Hayabusa is the eponymous example of a modern day ninja. His black falcon outfit's sleek design is reminiscent to that of the modern special ops agent; still, his tabi boots, ninja head piece, mask, scarf and shin/forearm guards are representative of the ancient ninja warrior. In great contrast to his deadly appearance, beneath the mask lies a handsome man capable of gentle expressions even, while still in his early 20s, Ryu's personality is that of a wise, composed man far older than himself. With this level of maturity, Ryu is perfectly able to act gentle and caring towards his relatives and friends, and very cold and deadly towards his enemies without hatred.

"Mizuki McCloud: "How did she [Ayane] know about this place? It's classified top secret…"
 * Animal Motifs: The Falcon, specifically the Peregrine Falcon
 * Meaningful Name: "Hayabusa" is the Japanese name for the bird.
 * Animorphism: Shown in the first Xbox game's ending, where he leaves by transforming into a falcon.
 * Anti Hero: Type III at his worst, but mostly Type II. Ninja Gaiden 3 elaborates more on this.
 * Back From the Dead: Quite instantly after being killed by Doku in the first Xbox game.
 * Badass: One the poster boys for ninjas in Video Games.
 * Badass Abnormal: Despite his original belief, Ryu's power does not come entirely from his training.
 * Badass Long Hair: His ponytail seen in his unmasked appearance for Ninja Gaiden: Dragon Sword. He cuts it off by Ninja Gaiden 3, and grows it back in Dead or Alive.
 * BFG: Howling Cannon
 * BFS: Dabilahro, Dark Dragon Blade, Emma Fang and Eclipse Scythe
 * Bishonen: His Dragon Sword appearance. Ninja Gaiden 3 reveals his whole face, as do alternate costumes in the Dead of Alive games.
 * Bow and Sword In Accord
 * Charles Atlas Superpower: Subverted, as Ryu did train intensively to reach the level of Master Ninja, but the cursed fiend blood in his veins gives him power above other ninjas.
 * Clear My Name: In The Ancient Ship of Doom, he's accused of assassinating Irene.
 * Death Is Cheap: After being killed by Doku, Ryu resurrected as fast as he died.
 * Green Eyes: Its tint of color tends to vary from game to game.
 * Hand Wave: At least in Ninja Gaiden 3.

Ryu: "Ninja have their ways.""


 * Happily Married: With Irene as of Dead of Alive; later games attempt to make it ambiguous by only going as far as to state they're still together.
 * Improbable Age: Ryu reached the rank of Master Ninja in his early 20s while other known masters are in their middle ages or older. Not only is he the strongest in his clan, but continuity (all the way to Dead or Alive) places him as the single most powerful ninja in the world.
 * Informed Attribute: The fact he became an antique shop owner in Dead or Alive was carried over from the OVAs, and even then it's only mentioned briefly in his bio. We don't actually get to see him running the shop, or see the shop itself for that matter.
 * Katanas Are Just Better: Quite literally, as despite a vast array of weapons Ryu finds, the Dragon Sword proves itself to be the best overall. Later justified since the True Dragon Sword is the only weapon in-universe capable enough to destroy Greater Fiends.
 * Ninja
 * The Other Darrin: English localization just can't get a hold of a voice actor for too long. As of Ninja Gaiden 3, there are three different actors for each main release. Troy Baker reprises his role, having provided his voice in Dead of Alive Dimensions. Compare and contrast to Hideyuki Hori, who has been voicing Ryu for 16 years, the first of which was the original Dead or Alive back in 1996.
 * Out of Character Moment: In the OVA, Ryu claims he would abandon his duties as a ninja in his clan, if it would mean being with Irene forever. Contrast how he's portrayed elsewhere, as he's bound by duty and honor. May double as a Screw Destiny.
 * Red Right Hand: In Ninja Gaiden 3, the Regent of the Mask curses him with the "Grip of Murder", forcing the Dragon Sword to be absorbed by his right arm. Doubles with Tainted Veins.
 * Stock Ninja Weaponry: Kunais, shurikens, claws, nunchaku and kusari-gama. The subversion would be the Dragon Sword, as it's a katana rather than a ninjato.
 * The Straight and Arrow Path: Goes up against opponents who wield machine guns or rocket launchers with nothing but his trusty bow, and more often than not comes out on top. He can even take out tanks and helicopters!
 * Wise Beyond Their Years

Ayane
"Voiced by: Wakana Yamazaki (JP), Janice Kawaye (EN)

Debuting in: Ninja Gaiden (Xbox)"



An immigrant from Dead or Alive, Ayane made her way into Ninja Gaiden in the Xbox Revival of the series. She is from the Hajin Mon sect of the Mugen Tenshin Ninja Clan, which is apparently on good terms and has ties with the Dragon Ninja Clan. Ayane is the primary choice for the Mugen Tenshin when they need assistance from the Dragon Clan as she has built a mutual friendship with Joe and Ryu Hayabusa. Even though he's leagues above her in rank, Ayane aids him on his missions, either by informing and helping from the sidelines or outright fighting alongside him.


 * Action Girl: Got her chance to shine in Sigma II.
 * Animal Motifs: Butterflies, from her choice of clothes, to their color and her inconic sash.
 * Art Evolution: To coincide with her appearance in Dead or Alive 5, Ayane will get this treatment for Ninja Gaiden III with smaller eyes, more realistic asiatic facial structure and modest measurements; the latter might not be seen as an "evolution", though.
 * Colour Coded for Your Convenience: Almost everything related to Ayane is purple, including her hair, clothes, aura, ninpo, explosive shurikens, etc.
 * Curtains Match the Window: Purple everywhere! However...
 * Technicolor Eyes: Certain cut-scenes depict them as red with shades of pink rather than purple.
 * Dangerously Short Skirt: The one she wears in Sigma 2 sure makes it easy to get a Panty Shot.
 * Demoted to Extra: Ayane only appears in Ninja Gaiden 3 to deliver a replacement sword for Ryu after losing the Dragon Sword due to the Grip of Murder.
 * Even in Ninja Gaiden II, she only shows up to give him the Eye of the Dragon (before Sigma 2 expands her role).
 * Easy Mode Mockery: In Ninja Gaiden Black, dying continuously in the first level results in Ayane giving the player the option to turn the difficulty down to "Ninja Dog". This results in her telling you that you suck for giving up at Normal difficulty; to further the mockery, she gives you ribbons to boost stats for the rest of the playthrough.
 * Fan Service Pack: In Ninja Gaiden, she wears pretty concealing clothes compared to her default attire in Dead or Alive; in the sequel, she gets more Stripperific and has noticeably bigger breasts.
 * Note a year has passed between the two games, and since she's supposedly in the middle of adolescence…
 * Fragile Speedster: The fastest character in Sigma II, but isn't as powerful as Ryu or Momiji.
 * Gameplay and Story Segregation: In-universe, Ayane would never dare talk back to Ryu, but not because he's a Master Ninja and she's ranks below him, but because he's one of the few people who don't ; of course, this won't stop her from mocking him for giving up at the Game Over screen, defaulting to "Ninja Dog" difficulty and presenting him with stat-boosting ribbons.
 * When "Ninja Dog" mode is selected, it also changes the default title screen to a picture of Ayane. The implication is that Ryu gets demoted to a true Ninja Dog, thereny making Ayane his superior and consequently becoming the main character. Now she's just insulting a Mook ninja, not the great Ryu Hayabusa.
 * Giant Waist Ribbon: Sports one in Sigma II as a Call Back to her Dead or Alive outfits.
 * Jerkass: Averted, as Ayane doesn't show much of her base personality from Dead or Alive in Ninja Gaiden, since she's dealing with mostly higher ranking ninjas like Ryu. Of course, this won't stop her from mocking him at the Game Over screen.
 * Jerk With a Heart of Gold: Ayane does treasure what friends she has and is ready to help Ryu and Dragon Ninja Clan whenever possible.
 * Kunoichi
 * Mysterious Watcher: Her appearance in Ninja Gaiden from start to finish.
 * You Gotta Have Purple Hair
 * Younger Than They Look: Mind you, Ayane doesn't look her age even in her home series (she's 16 in Dead or Alive). In Ninja Gaiden she's 14 years old, then a year older in Sigma II.

Doku
"Voiced by: Koji Totani (JP), Charles Dennis (EN)

Debuting in: Ninja Gaiden (Xbox)"



One of the Three Greater Fiends of the Holy Vigoorian Empire, Doku is a fiend incased in a heavy, dark suit of armor, closely resembling an ancient Samurai. He singlehandly destroyed the Hayabusa Village, killing many of the Dragon Clan Ninjas and stole the Dark Dragon Blade. Doku's goal is to aid his master, the Dark God Vigoor, into converting capable people into fiends and conquering the world. Doku is Ryu's motivation to invade Vigoor, as he also killed his childhood friend Kureha. Although Ryu manages to find and defeat him, Doku's last resort is an attempt to transform the ninja into a fiend, but the transformation is only partial as Doku's disembodied spirit fades away.

Doku returns in Ninja Gaiden: Dragon Sword as a malevolent spirit haunting the ruins of Tairon.


 * Back From the Dead: Although Ryu destroys his initial body, Doku returns in a spirit form for a final showdown. How he manages to show up in Dragon Sword isn't answered.
 * BFS: Kitetsu.
 * Black Knight: Bonus points for Doku as the black armor is his actual body.
 * Tin Tyrant
 * The Dragon: Answers directly to Marbus, who answers to Vigoor.
 * The Faceless: Since Doku doesn't have a proper body to begin with, he has no face to portray himself. Instead, he wears a mask as part of his armor.
 * Hopeless Boss Fight: It's nigh impossible to defeat him in the first fight in Sigma, unless you're an insanely skilled player. But even if you do, Ryu will die after the fight regardless.
 * Lightning Bruiser: While very heavy, Doku's capable of pulling off some fast-paced combos and slashes.
 * Obviously Evil: As if his introduction cutscene wasn't enough, Doku reeks of evil from head to toes.
 * Recurring Boss: Three times in the same game.
 * Spikes of Villainy: Less than normal, but still there.
 * Taking You With Me: In his final moments, Doku curses Ryu in an attempt to convert him into a fiend and serve Vigoor.

Elizébet
"Voiced by: Hiromi Tsuru (JP), Grey Delisle (EN)

Debuting in: Ninja Gaiden II (Xbox 360)"



The Ruler of Crimson Blood and Queen of the Greater Fiends, Elizébet is the most active villain during Ninja Gaiden II for Xbox 360, also one of Vazdah's Four Deadly Greater Fiend Lords, and the blood priestess of the Fiend cult, the Order of the Necromantale. Elizébet was tasked with retrieving an important ancient artifact from the ancestral Hayabusa Village. For this she aproached the Black Spider Ninja Clan to help her with the task. In return Genshin and his followers were rewarded with fiend powers to overthrow the Dragon Ninja Clan. Later Elizébet manages to trigger Ryu's anger by capturing Sonia and spitting on Genshin's pride after she resurrects him as a complete fiend. Out of all Greater Fiends she is likely to be the one who really earned Ryu's hatred by corrupting the Black Spider Ninja Clan.


 * Aristocrats Are Evil: One of few Greater Fiends who are actually said to be a noble, and of course Elizébet is one of the most evil among them.
 * Beauty Is Never Tarnished: Her form as a Greater Fiend is nowhere as demonic looking as the other three Vazdah's Deadly Greater Fiend Lords.
 * Which leads to incredible Squick since her abdomen shows off her internal organs.
 * Beware My Stinger Tail: She will regularly try to stab you with her tail. It's not very difficult to dodge, but you'd better dodge it.
 * Blood Bath: Elizébet sure enjoys her job as the blood priestess of the Fiend cult.
 * Bloody Murder: A very vicious long range attack has her sending multiple blood spears at you, which are not only very damaging but also refill her lifebar as they hit you.
 * Fan Service: The cutscene preceding your first boss battle with her in Ninja Gaiden 2.
 * Femme Fatale: So much that Elizébet is the only Greater Fiend Lord that bothers assuming a human form. She likes to look that poisonous.
 * God Save Us From the Queen: Queen of the Greater Fiends, not much else to be said.
 * Horny Devils: Both Elizébet's human and fiend forms are very sexually suggestive.
 * Impossibly Low Neckline: Justified in that what is holding her breasts sure aren't part of her clothes.
 * Informed Ability: The Queen of the Greater Fiends sure doesn't look that royal, both Marbus and the Dark God Vigoor have shown that they hold much more ground and followers than Elizébet did.
 * Kick the Dog: Literally kicked Genshin in the head after he was killed yet again by Ryu, spitting on the fallen warrior's pride while at it.
 * Meaningful Name: Elizébet's personality and her bloody design, akin to Elizabeth Bathory.
 * Manipulative Bitch: She sought the Black Spider Ninja Clan to help her steal the Demon Statue from the Dragon Ninja Clan, in return she would give them demonic powers, and she did give them power, but of course Elizébet forgot to tell them she sees them as disposable objects and eventually they would fall.
 * One Winged Angel: The only Vazdah's Deadly Greater Fiend Lord who wasn't already transformed to fight against Ryu.
 * The Power of Blood: Ruler of Crimson Blood...
 * The Smurfette Principle: The only woman among Vazdah's Deadly Greater Fiend Lords, and the only relevant female Greater Fiend in the whole series.
 * Stripperiffic: In human form only her torso looks like this, as a Greater Fiend she fits better.

Gamov
"Voiced by: Hisao Egawa (JP), Robin Atkin Downes (EN)

Debuting in: Ninja Gaiden (Xbox)"



The man delivering orders to the Vigoorian forces in the first Xbox game, Gamov is a bespectacled, green hat and coat wearing spy, who constantly trails Ryu through the Holy Vigoor Empire, proving himself very agile and quick in the trigger while facing Rachel, he was supposedly working together with Doku for the Dark God Vigoor, in reality Gamov really served the Dark Disciple as he managed to bring the Dark Dragon Blade to his master, but he was killed by the Dark Disciple as soon as the sword was in his hands; the sequel for the Xbox 360 gives more background on Gamov, especially justifying why he was so agile back then, he was Genshin's younger brother and part of the Black Spider Ninja Clan.


 * All There in the Manual: That Gamov came from the Black Spider Ninja Clan and was Genshin's younger brother is not mentioned in the main story. You have to find Genshin's diary and read the entry about his dead young brother.
 * Badass in A Nice Suit: Gamov certainly doesn't look like he came from a Ninja Clan, the way he dresses and all.
 * The Dragon: For Murai the Dark Disciple.
 * Guns Akimbo: Packs two pistols in the fight against Rachel in Sigma, among other things.
 * The Gunslinger: Gamov proved to be quite a skilled one in Sigma against Rachel.

 * Mysterious Watcher: Trailing Ryu through the Vigoor Empire.
 * Not So Harmless: Ryu got a strange feeling from Gamov when fell off the club's edge, also Gamov's fight against Rachel.
 * Off With His Head: The way Murai showed gratitude to Gamov.
 * You Have Outlived Your Usefulness: Gamov got offed as soon as he gave the Dark Dragon Blade to Murai.

Genshin
"Voiced by: Ryuzaburo Otomo (JP), Neil Kaplan (EN)

The Ninja Overlord, Master Ninja of the Black Spider Ninja Clan and later one of the Five Greater Fiends of Vazdah in the Xbox 360 game, Genshin is the best and most ruthless ninja the Spider Clan has ever created, with eternal lust for power and hatred towards the Dragon Ninja Clan, he didn't think twice when Elizébet offered him more power for his clan and an excuse to anihililate the whole dragon lineage and its followers. Genshin successfuly destroyed great part of the Dragon Ninjas' village up to fighting against Joe Hayabusa, and managed to steal the Demon Statue for Elizébet; Ryu fights against Genshin four times during the story, in the third he kills him, the fourth Genshin is ressurected by Elizébet as a Greater Fiend, but Ryu once again prevails and finished Genshin off once for all, also despite Genshin's hatred for Ryu's clan it seems both of them developed a less harmful rivalry during their fights, it is clear that when Genshin died most of his hatred was gone as well, Ryu was really infuriated when Elizébet spit on Genshin's pride.


 * Above Good and Evil: Joe Hayabusa acuses Genshin's clan to be corrupted by evil, Genshin remarks that the ninja way knows neither good nor evil.
 * Animal Motifs: The Spider, his armor has this theme.
 * Arch Enemy: Of the entire Dragon Lineage.

 * Back From the Dead: Died in his third fight against Ryu, Elizébet resurrected Genshin as a Vazdah Greater Fiend.
 * Badass: Genshin reeks of badassery, leading the Black Spider Ninja Clan through sheer power and proving his skills are worthy of a Master Ninja.
 * Badass Abnormal: When he comes back as a Vazdah Greater Fiend.
 * Benevolent Boss: While Genshin is credited for being a ruthless and violent Overlord, many Spider Ninjas seems to adore and respect him, many Spider Clan scrolls will note how respectable Genshin is.
 * BFS: Blade of The Archfiend.
 * Dark Skinned Blond: A male variation.
 * Driven By Envy: The Black Spider Ninja Clan being in the Dragon Ninja Clan's shadow for generations took its toll on Genshin, he grew to hate Dragon Lineage entirely, their downfall is Genshin's ultimate goal.
 * Its Personal: Genshin's entire motivation for going along Elizébet plans, he really wants the Dragon Lineage to be extinct.
 * Large and In Charge: Genshin borders on giant, even towering some of his Ninjas that were converted into fiends while still a human, and of course Genshin is the one in charge.
 * Lightning Bruiser: Powerful and fast, very fast; Genshin is just too damn fast, an athletic Ninja like Ryu has to keep his eyes focused against a gian like Genshin due his speed.
 * Mirror Boss: To an extent - he can use the Flying Swallow, the counter-attack, the Piercing Void Ninpo (in Sigma II only), has an Ultimate Technique similar to Ryu's in Greater Fiend form, and Ryu picks up his Underworld Drop after getting the Blade of the Archfiend.

Kureha
"Voiced by: Jun Shikano (JP)

Debuting in: Ninja Gaiden (Xbox)"



The Dragon Shrine Maiden of the Dragon Ninja Clan, sworn to protect the Eye of the Dragon, Momiji's older sister and Ryu's childhood friend, Kureha is part of the Dragon Lineage was destined to play part in keeping the clan's tradition, being inseperable from Ryu since childhood she also wanted to be of importance, while he grew up to be a Master Ninja, she grew up to be a Shrine Maiden. Then as guardian of the Dragon Lineage Shrine, she was charged with the protection of the Eye of the Dragon, Kureha fufilled her task to death as Doku killed her in an attempt to steal the Eye of the Dragon; it was for her that Ryu went on a quest for vengeance towards Doku. Kureha briefly returns as an spirit in the sequel for the DS, aiding Ryu and Momiji against the Dark Dragon.


 * Childhood Friends: With Ryu Hayabusa.
 * Death By Origin Story: Kureha's early death in the game triggers Ryu to a long and vengeful mission.
 * Disposable Woman: Originally, Kureha only existed motivate to Ryu with her cruel death, even though she would become relevant in the NDS game later. One can wonder why she has a voice actor credited in the Xbox game since we never hear a word from her.
 * MacGuffin Guardian: In the normal sense, Kureha is just a shrine maiden tasked with protecting the Dragon Clan's treasure Eye of the Dragon.
 * Miko: For the Dragon Ninja Clan, as being part of the Dragon Lineage is a requirement to be the village's shrine maiden, Kureha was fated to be one since childhood.
 * Non Dubbed Grunts: In the japanese track for the first Ninja Gaiden, Kureha has a weak death cry in her final moments, while in english track she hasn't. That's why there's no credited voice actress in the american version of the game; Jun Shikano reprises her role of "grunts" in Dragon Sword, which in fact she is right at home, as the characters in the game are portrayed in The Legend of Zelda grunts-only style.
 * The Obi Wan: To Momiji in Dragon Sword.
 * Passing the Torch: Kureha, as a spirit, hopes that Momiji will take on her sister's duty as a shrine maiden.
 * Posthumous Character: Kureha's background is explored in the first Xbox game's sequel for NDS.

Marbus
"Voiced by: Yukitoshi Hori (JP), Fred Tatasciore (EN - NGSII)

Debuting in: Ninja Gaiden (Xbox)"



Ruler of Hell and one of the Five Greater Fiend Lords of Vigoor in the first Xbox and returning for the PS3 sequel, Marbus is the Greater Fiend who guards the Holy Vigoor Emperor, the mastermind behind the theft of the Dark Dragon Blade; in contrast to other Greater Fiends, Marbus has legions of lesser fiends as his direct followers, often leaving the dirty work for them only acting himself when he sees fit or worthy, Ryu happened to be one these worthy as Marbus was forced to take him on directly, the result was the Greater Fiend losing and targeting Ryu for his personal revenge in the future. Marbus returns in Sigma II looking for Ryu to exact his revenge upon him, he finds Rachel instead and is defeated once again.


 * Art Evolution: Marbus' design changed quite a bit when he came back in Sigma II.
 * Ascended Extra: Marbus in Sigma II comes back with a sudden character, he is now full of hatred against Ryu, full of lines and more demoniac than ever.
 * Cool Chair: Fitting for the Archfiend of Hell.
 * The Dragon: To Dark God Vigoor.
 * Dragon With an Agenda: That said, Marbus doesn't seem very concerned about his master being dead, when he comes back in Sigma II, Marbus is concerned more about his realm and himself being defeated by Ryu.
 * Flat Character: For someone who is said to be behind everything Doku did, Marbus got much less exposition than his subordinate, ironically he gets more exposition in his small role for Sigma II.
 * Flunky Boss: The only boss to be that way in Normal in the first game. He actually uses minor bosses as flunkies. And in higher difficulties he hides behind Nicchae and Ishtaros... who are actually harder than he is.
 * Its All About Me: Marbus in Sigma II seemed more upset about Ryu defeating him than killing his supposed master Dark God Vigoor.
 * Its Personal: With Ryu, Marbus being defeated by the Ninja left more issues than his master being killed.
 * Meaningful Name: Marbus the same as Marbas the President of Hell from The Divine Comedy's Dante's Inferno, where he rules over 36 legions of demons, just like Marbus who has control over many fiends for himself.
 * Not Quite Dead: As seen in Sigma II, Ryu didn't kill Marbus in the first game, he just left him scarred and with one horn less.
 * Revenge: Against Ryu, Marbus lets more off that it is about his defeat rather than his dead master.
 * Scars Are Forever: While it didn't look like that in the first game, Ryu apparently cut one of Marbus' horns off and left him with a few scars as seen in Sigma II.
 * Slouch of Villainy: Marbus does a good impression while he waits for Ryu to face off against his minions in the first game.

 * MacGuffin Guardian: In the normal sense same as Kureha, Momiji is not only a Ninja but a shrine maiden tasked with protecting the Dragon Clan's treasure Eye of the Dragon.
 * The Medic: Sort of. She uses her powers to soothe the pain in Ryu's cursed arm in Ninja Gaiden 3.
 * Miko: Replaced Kureha at being the guardian of the Eye of The Dragon, now Momiji is a Ninja and a Miko.
 * My Greatest Failure: Momiji blames herself for Kureha's death to some extent, she was taking her Ninja training in another village at the time while Doku wrecked the Hayabusa Village and killed her sister.
 * Ninja: Originally she was only this, a Ninja (or rather Kunoichi) in training, then Kureha dies and Momiji had no other choice but to replace her sister due their Dragon Lineage.
 * Someone Has to Do It: Momiji could not refuse being a shrine maiden even if she wanted to, her distinguished lineage gave the final word.
 * Throw the Dog A Bone: After some dead older sister and self-depreciating heroine arroy, Momiji gets to impress the clan's Master Ninja Ryu himself to train her personally due her determination in getting stronger for Kureha and to protect the clan's children, the results are shown in Sigma II where Momiji definitely has gotten a lot stronger.

The leader of the Shadow Clan Ninja and Ryu's maternal uncle, Murai is a former member of the Dragon Ninja Clan who went rogue and formed his own Ninja Clan, while prefering to stay away from the Dragon Clan's affairs, Murai still wanted to keep a good relationship with his former clan thus aiding his nephew by opening the Shadow Clan fortress for Ryu's training routine. Murai is open about his extreme philosophy of the ever increasing need for power a true ninja must possess no matter the costs, so he tries to push some of it to his nephew Ryu by trying to make him accept the Dark Dragon Blade, still Ryu declines. As the Dark Disciple, Murai reveals to be behind every ploy to steal the Dark Dragon Blade, his madness for power only went that far as Ryu in the end killed his uncle.

 * Evil Uncle: Of Ryu Hayabusa, mother side. Murai watched in the sidelines as his nephew struggled to save the Hayabusa Village and recover the Dark Dragon Blade; in the end Murai was behind everything.
 * Face Heel Turn: Prior to the series itself, Murai once was a honorable ninja from the Dragon Ninja Clan.
 * Fighting With Chucks: Murai's skills with the nunchakus are to be praised, when Ryu has them his usage doesn't compare to that of Murai's, both in power and speed.
 * Large and In Charge: From the very little we get see about the Shadow Clan, Murai seems to be the tallest and most muscular out of the bunch, and of course he is the leader.
 * Lightning Bruiser: Fast and powerful as the first boss, slower as the last but still capable of some nasty rush downs.
 * The Man Behind the Man: As the Dark Disciple, Murai was eventually behind everything.
 * Manipulative Bastard: Murai let the Dark Dragon Blade switch from hand to hand intentionaly before he got his own hands on it, that way it could absorb more evil energy.

Muramasa
"Voiced by: Takeshi Aono (JP), Michael Bell (EN)

Debuting in: Ninja Gaiden (Xbox)"



The legendary weapon smith and shop owner who aids Ryu on his journeys, Muramasa is a fairly mysterious merchant who seems to have traveled across the entire earth, he knows everything there is to know about relics and antiques alike; Muramasa's known feats are him personally erecting all the statues sculpted in his image that Ryu comes across much of the time, his vast knowledge of antiques and his past as a very skilled swordmaster; concerning his skills with a sword, Muramasa seems to still know a few tricks despite his advanced age as seen in Sigma II.


 * Adam Smith Hates Your Guts: The price of weapon upgrades increases with the levels, so thousands of yellow essence will be spent upgrading weapons with many levels; Wooden Sword in particular will make some players focus solely on it and leaving other weapons behind to reach the maximum level.
 * Inverted in Sigma 2 where weapon upgrades are free (but you can only upgrade one weapon at a time) and bringing him crystal skulls gives you a permanent discount. Finding the 30 skulls halves the price of healing items, which is quite helpful in higher difficulties.
 * Back Stab: Muramasa sneaks behind one unsuspecting Ninja in Sigma II and backstabs him with a mantis sword.
 * Badass Grandpa: Muramasa still does some impressive things even in his advanced age, he still shows some skills with swords and can take care of himself pretty well as Ninjas who try to wreck his shop don't succeed in killing him.
 * The Blacksmith: Muramasa personally upgrades all of Ryu's weapons if given enough yellow essence.
 * Ultimate Blacksmith: That said, only Muramasa can handle all these legendary or downright demoniac weapons that Ryu possesses.
 * Canon Immigrant: Muramasa appears in Dead or Alive, the 4th in particular; now owning a small Vegetable Mart, in which Lei-Fang and Hitomi fights over a cabbage.
 * Cool Old Guy: Muramasa is said to be above 100 years old, and he still is a fairly modern guy, funny even.
 * Exposition Fairy: Muramasa often lets out some plot points that Ryu needs to advance in his journey.
 * Mr. Exposition: In his introduction scenes Muramasa lets out directions about a place Ryu needs to go or about the situation the Ninja currently finds himself in.
 * Non Dubbed Grunts: Most of Muramasa's average grunts for an elder aren't dubbed, they're straight from the Japanese track, unlike other characters who got their grunts dubbed.
 * Not So Harmless: As seen in Sigma II against a hidden Ninja, Muramasa still has some tricks up his sleeve.
 * Too Long Didn't Dub: Muramasa's greetings aren't dubbed in Ninja Gaiden II and Sigma II, he says Irasshai instead of Welcome to Ryu when his shop is accessed, which isn't even long anyway.
 * Walking the Earth: Prior to the games, it is said that Muramasa personally erected all of his statues that Ryu eventually finds in his journey, every single one of them.
 * Which would include those in the Underworld... that's some prowess indeed.

The main girl for Ninja Gaiden (Xbox) and fiend hunter from the Holy Vigoor Empire, Rachel is somewhat a tragic heroine. She and her sister Alma were afflicted with a blood curse that turns humans into fiends. By the events of the game Alma has already succunbed into a complete fiend. Rachel still maintains her human form and becomes a fiend hunter; believing that her sister has no more chance to revert back, Rachel sets on a journey to put Alma out of her misery. Rachel gets caught up in Doku's plot to bait Ryu, as the Greater Fiend also has Alma under his control. Rachel pursued him only to get captured herself; Ryu manages to rescue Rachel and in return she saves him in time for the final bout against the Dark Disciple.

 * Action Girl: While playable in Sigma, becomes a full-fledged one in Sigma II.
 * Big Damn Heroes: Rachel helps Ryu escape the Underworld of what it seemed a certain death for the Ninja.

 * Distressed Damsel: After Doku captures her, Rachel spends the rest of the story like this.
 * Dogged Nice Girl: In a rare female example, Rachel by the end of the first Xbox game has taken quite a liking to Ryu, but he promptly seems to refuse, and going by the series' continuity Rachel isn't going anywhere with Ryu.
 * Drop the Hammer: War Hammer (which looks like an axe instead) in the first game, Inferno Hammer (which looks like a hammer this time around) in Sigma II.
 * Faux Action Girl: In the original Xbox game Rachel wasn't playable so in story segments she falls straight into this.
 * Gatling Good: Rachel sports a Gatling Gun as her projectile weapon in Sigma II.

 * Waif Fu: Rachel is very strong despite her slender figure, due her cursed fiend blood she can best enemies many times her size and obviously more muscular than her.

Different from her NES counterpart, Sonia is not so harmless, she proved herself to be quite dependable and gutsy when fiends are not involved; when fiends are involved however, Ryu is up to task and ready to rescue Sonia.
