Beware the Nice Ones/Video Games

"Engineer: I appreciate that you're my employer, and an old man besides... but if you don't take your goddamn hands off me I will break you in half."
 * The normally-patient, soft-spoken, and all-around good ol' boy, The Engineer, a.k.a. Dell Conagher, from Team Fortress 2. While being physically-accosted by his employer who (by product of the Not-Dying Machine his grandfather built) is electrocuting him, calmly and insistently states the following:

"Lulu: I hope you hurt them. Yuna: (modestly) A little."
 * The Halo novels confirm this for Cortana. She's a nice, somewhat snarky, AI who will get you transferred onto the front line and ruin your marriage if you mess with her or John.
 * Amy Rose of Sonic the Hedgehog.
 * Her sidekick Cream the Rabbit, and her pet sidekick Cheese the Chao. She's amazingly polite, gentle, and nice to everyone. However, if you try to diss her off in anyway (particularly you, Dr. Eggman), she'll beat the living daylights out of you using her pet Chao. As if her Game Breaker status in her debut title wasn't enough of a clue.
 * Try to kill Sonic when Tails is around. Just try it. He'll end your ass if you do, as Eggman found the hard way in Sonic Adventure 2
 * Sonic himself is generally an easy-going free spirit with no real ill will towards anyone. Cross anyone he cares about, however, and he'll plow through armies at Mach 3 to neutralize you, and that's when he's not even angry. Provoke him enough, and, provided he has the Chaos Emeralds around, he'll go Super Mode on your ass. Super Sonic is a Game Breaker of epic proportions.
 * Janos Audron of Legacy of Kain. In Soul Reaver 2 he's a kind old mystic and the only person who's relatively straight with Raziel. In Defiance he's even more so, with a dash of woobieness when he starts to realize everything he's been enduring centuries of isolation for has been wrong...
 * In the Fate/stay night visual novel, the "Heaven's Feel" scenario branch culminates in
 * Happens a lot with Nasuverse characters. The ever happy is completely insane. Even Arcueid has her moments of this.
 * The title character from Mega Man X. Having just watched Zero, X regains all his health and proceeds to dispense an asswhooping on Vile and then Sigma.
 * Maybe because X wasn't really one of the titular "Nice Ones," just a Technical Pacifist, and has been beating up robot masters for quite a while before the scene you're referring to takes place.
 * The predecessor Rock, though. Rock would be happy to while away his days as a lab assistant. When someone tries to use robots to attack people, though, he becomes Mega Man. He will plow through their forces, take their weapons to become a walking arsenal, and dismantle everything that stands between him and the threat. Lest you think Humongous Mecha will faze him, fuggedaboutit.
 * Especially in some of the later games, the original Mega Man nearly blows Wily away for good.
 * X in the Maverick Hunter X movie Day of Sigma definitely counts. Since it's set before the game, X was nothing more than a hesitant, unsure Hunter who took down criminals. Zero even remarks on how kind and sensitive X is. Then X scars Sigma's face with his bare hands after being stabbed in the gut.
 * Let's not forget Iris from X4. Kill a girl's brother, and that sweet little British girl in a beret will come after you in a giant purple mecha suit.
 * A manga adaptation of X2 as X being so disgusted with the fallout of the first game's events that he put a seal on his arm cannon (he thought only his left arm could transform; that lack of knowledge had a hand in Zero's death). After his unit is killed by a traitorous subordinate, X finally undoes it and fires his X-buster.
 * Patrick Sprigs from Mega Man Star Force generally acts mild mannered and sympathetic, yet secretly harbors hatred towards the parents who abandoned him, which violently manifests itself as his Split Personality Rey.
 * In Mega Man Battle Network 3 Littlest Cancer Patient Mamoru
 * Which is justified by the nature of the thing in question, as well as the fact that
 * Hibiki Takane of the Last Blade series is usually a kind, meek individual, who fights reluctantly. However, if the player keeps killing her opponents, she'll gain new win quotes and win poses included, and eventually a new ending that show her to have become a deranged murderer.
 * Vivi of Final Fantasy IX is sweet, innocent, kind, and despite his species, looks massively adorable, so naturally he has powerful black magic up the ying-yang. Most notably during the battle with Black Waltz 3 where the little guy just went ballistic.
 * In Super Robot Wars Gaiden, Tytti Noorbuck is considered one of the more nicer, gentle-hearted pilot. Except at one occasion when she found out that Ricardo Silvera have attempted a prank on her 'little brother' Masaki. What happens next was her furiously choking Ricardo, while keeping a smiling face (good thing she's stopped early). Conversely, she completely drops the 'Nice one' persona when she faces her arch-enemy Lubikka Hakinnen, due to many reasons.
 * The Seraphim, and to a lesser extent, the Aeon Illuminate of Supreme Commander are more or less defined by this trope-they're normally devoted to nothing but peace, love, and hope. Force them into fighting, and they try to make the fight as short and painless as possible. In this case, "short and painless" involves genocide in the form of planetary-scale bombing runs, nuclear strikes, liberal usage of Humongous Mecha, and massive waves of land, air, and naval robots of increasing size and firepower.
 * In Knights of the Old Republic Juhani is actually quite sweet when she is calm. You do not want to make her angry. Ever.
 * Bastila is a relatively nice person most of the time, but she does happen to have enough Force power to change the course of any battle ever.
 * Several more are like this. Carth? Genuine Nice Guy. Pulls you out of an escape pod and nurses you back to health. Takes it upon himself to act as your voice of conscience. Mention Saul Karath and your will had better be made out.
 * Zaalbar? Painfully shy Gentle Giant and very honorable young Wookiee...who can still rip your arms out and beat you to death with them.
 * Mission? Very sweet-natured teenager, forgiving to the point where it can be a Fatal Flaw...and lived by herself in one of the worst Wretched Hives in the galaxy.
 * Safiya of Neverwinter Nights 2 is a very kind person most of the time. Until you threaten her mother or her golems.
 * Deekin of the original Neverwinter Nights. Clumsy, awkward, not the brightest of folk. Has enough balls to talk back to offending demigods.
 * Mass Effect:
 * The turians are generally pretty nice guys, are almost all unbelievably polite. They're heavily militarized, but strongly civic-minded, highly responsible, steadfastly loyal, place the greater good before the individual, and are quite willing to work with and protect other, weaker civilizations or species. And if you provoke them into war, they make damn sure you are never able or willing go to war with them again. Ever. They conquer everyone they fight . But give you compensation afterward, just to make it perfectly clear how well this fits.
 * Liara's level of niceness is over nine thousand, but her powers are such that she can telekinetically bench-press a Geth Colossus (which is, for the record, as large as a three-story building), and launch people practically into orbit by thinking at them hard. Even Wrex makes a point of noting how damn powerful she is.
 * Kaidan Alenko is a relaxed, dorky type with absolutely no weapon skills available. But he can fire people into the sun with his mind and cause biological enemies to have toxic-flavoured seizures.
 * Tali is seen as being very polite and kind to most of her fellow crew members. If she runs across someone who she sees as evil, though, she can be... surprisingly vindictive. And amusingly creative.
 * Garrus. Calm, pretty well-adjusted, enjoys a good laugh. Break the law while on the same facility as him, and you'd better be on the next shuttle to anywhere else. And even that won't ensure your safety. This is the man who once pissed off three entire mercenary armies, and they spent an entire weekend trying to kill him and failing.
 * Heck, arguably all the Council Member races are like this. Including humanity. The salarians might seem weak and science-y but cross them and they'll wipe your species out.
 * No kidding. The Codex even says that salarian military doctrine does not include formal declarations of war. If they're openly attacking you, it's because you've already lost.
 * Commander Shepard him/herself can be the kindest, gentlest, supreme Paragon in the game. But even when played this way, s/he still gets a good share of ruthlessness, from threatening one of his/her crew with a gun to telling off news reporters who question him/her. S/he is also known for plowing through armies of geth, mercenaries, or Collectors and killing and pissing off Reapers.
 * In Mass Effect 2, Joker himself notes that Jacob is much too nice for a professional soldier.
 * Mordin is a doctor and one of the most helpful of characters, and also one of the most ruthless party members who easily butchered a few mercenaries that attempted to attack his clinic. And hung their corpses out front as a warning to anyone else who would try,
 * One of Zaeed Massani's old war stories include being nearly strangled to death by a hanar, a jellyfish-like race whose racial hat is unceasing politeness and piety.
 * Kasumi is probably the most social and outwardly altruistic character in the second game, but if you piss her off she'll turn invisible and shoot you in the face or Parkour her way onto your ship.
 * The title character of Conkers Bad Fur Day was already having a bad day - as the title implies. All he wanted to do was to go home after a night of drinking, encountering Vampires, Zombies, bloodthirsty Dogfish, Cavemen, Dinosaurs, Robotic Haystacks, a horde of evil Tediz and a gigantic, opera-singing turd. And more. He's remained almost saintishly calm, up until the last level, where
 * World of Warcraft's Draenei are often stereotyped as goody-two-shoes. However, this Bloodmyst Isle quest requires players to capture the zone boss's chief flunky. In a cut scene after the quest is complete, the flunky repeatedly taunts a Draenei paladin NPC . The paladin snaps.
 * Note the spell he uses "Hammer of Vindication, 100 yd range, Instantly Kills the target. I hope you feel good about yourself now....." He is one of the few Alliance NPCs on Bloodmyst not flagged for PvP hehe.
 * Thrall.
 * In a quest for Hunters, you have to kill four demons. The demons are in an alternate form. All of them are passive, and when spoken to, will respond cheerfully and positively, unless you are a Hunter. Three out of these four demons will use Fool's Plight on you if you even do as much as strike them.
 * In Cataclysm, there is the Shaman Erunak Stonespeaker within Vashj'ir. Very polite, saves your life a couple times, and doesn't seem very condusive to combat. Indeed, he doesn't get any combat... Believe me. You do NOT want to mess with this guy.
 * Cairne Bloodhoof, former chieftan of the Tauren. Very calm and peaceful guy. Kicked the ass of Warchief Garrosh Hellscream until trechary saw the end of his life. His son, Baine Bloodhoof, is basically the same way.
 * Guildmaster Wigglytuff of Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness is a fluffy pink rabbit who just wants to be everyone's friend. However, at one point in the game, This is mentioned as happening before when
 * Selphie of Final Fantasy VIII. She's a cute, perky, friendly sixteen-year-old Genki Girl. She's also a trained mercenary with a highly-developed sense of overkill, and if you make her mad, she'll see to it that you become a smear of red gel on the pavement. Or, if you make her really mad, she'll wish you into the cornfield with her Limit "The End".
 * Monkey Pink just wants to be a star. But if you screw up her performance, she will try to kill you.
 * Flonne of Disgaea: Hour of Darkness. The Trope Namer for Love Freak, and a complete airhead, she will nonetheless go into a fiery-eyed rage if she's angered.
 * If Kingdom Hearts has shown one thing, it's that it's probably not a good idea to hack off Mickey Mouse...
 * To say nothing of the series' main character Sora. A happy-go-lucky kid who to date has defeated one thousand enemies in one fight, defeated most of the Disney villains at least once, and once cut a skyscraper in half and threw the pieces back at his opponent. (To be fair, the laws of physics weren't exactly in play during that last part, but still.)
 * We also learn that Goofy is capable of killing a man.
 * With only his shield at that, his character profile from the first game states that he flatly refuses too carry a sword or any other weapon of war, despite being Guard-Captain of the Royal Court Army in Disney Kingdom.
 * Mia Fey of Ace Attorney is a sweet caring Obi Wan always there to give a comforting word to to her former student Phoenix Wright and little sister Maya Fey--or, if your name is, there to kick your ass all the way back to hell with a mere speech. Did we mention that Mia's been dead since the first game?
 * On a similar note, Phoenix, Edgeworth, and Gumshoe are all varying degrees of nice and personable. But if you committed murder they WILL find you guilty. When Maya's life was at stake Gumshoe became competent. GUMSHOE.
 * This is in fact a major part of Edgeworth's Character Development: he started out as a brilliant prosecutor who did not care if the people on trial were actually guilty; and he managed to win every single case before meeting Phoenix in court. He then realized that a "guilty" verdict is not the most important thing in the world. But if he knows you actually did commit a serious crime, not even Phoenix Wright can save you.
 * Yuna of Final Fantasy X. More in the sequel, but still in the original. To point: Yuna is captured by the Al Bhed. Tidus, Lulu, and Kimahri try to rescue her. After beating a boss, Yuna walks out of the hold on the boat she was imprisoned in, completely unharmed, and a guard slumps to the ground.

"Pink: *Sigh*... That's what they get for making Aqua mad... Black: Oh, Aqua's scarier than anyone when she's angry... Aqua: HMPF!"
 * Yuna is mostly the type who rather stays back in a fight and lets Auron, Khimari and Wakka or the Aeons handle the physical fighting. Though she keeps to casting healing and protective spells, you later learn why everyone is practically falling on their knees before her, and Badass Longcoat Auron and Kuudere Lulu allow her to run the show entirely as she sees fit.
 * Don't forget the sheer amount of damage Yuna's Aeons can cause. A fully charged Overdrive with the later Aeons can defeat most bosses single-handedly.
 * Early on she also can dish out more damage then the resident Black Mage Lulu if taught offensive spells.
 * In BioShock (series) you see the aftereffects of an object lesson in just how dangerous Little Sisters' Nigh Invulnerability can make them if they're pushed far enough -- in the area where they're converted, trained, and harvested, you find a corpse nailed to a wall with about a half-dozen of their giant syringes.
 * Also seen in the ending,.
 * Welkin in Valkyria Chronicles is more of an Officer and a Gentleman. His little sister Isara is a different story. When she and her pregnant neighbor are threatened by two imperial soldiers, she grabs a rifle and shots one of them in the back when Welkin arrives to save them. And THEN she goes to the barn to get their fathers OLD TANK!
 * When Aeka told Antoinette to kill her in Yume Miru Kusuri to just get it over with and kill her already instead of needling her, it wasn't her being suicidal. It was a warning that if you keep pushing her she's eventually simply going to snap.
 * Leliana from Dragon Age is a sweet, fluffy, girly girl who used to be a nun. She wants to show mercy to practically every sentient being you meet that isn't a soulless husk of pure rampaging evil, and the main character loses her approval every time s/he chooses an evil or selfish action. She's also a retired spy/assassin who's killed more people than she can even remember and can be leveled up into one of the single most devastating ranged attackers possible in the game.
 * Also, Sandal. A young and innocent Idiot Savant who can only say "Enchantment" in various inflections, you stumble across him for the last time just before the fight with the Big Bad. He's alone, unarmed, covered in blood, and surrounded by heaps of Darkspawn corpses (including two Ogres). When asked what happened he of course responds with only a cheerful "Enchantment!"
 * Merrill in Dragon Age 2 is a sweet, innocent, Adorkable young woman who is the most selflessly kind character in the entire game and a walking incarnation of Moe. She is also a powerful blood mage and her entire available spell list is focused solely on multiple methods of inflicting horrible death.
 * And Sandal deserves mention here as well, seeing as he takes out a roomful of Abominations and Demons, including a 'Pride Demon', right before the final battle, while still having the same Cloud Cookoo Lander personality as before. Not to mention his creepy prophecy that comes out of nowhere... Interestingly, when asked how he defeated an ogre (which is somehow frozen) he says, "NOT enchantment."
 * Wu Zi Mu of Grand Theft Auto: San Andreas, or "Woozie" to his friends, is a laid-back, friendly, unassuming Chinese man who enjoys playing video games, racing cars, and golf. He's also the boss of the Mountain Cloud Boys, a Triad sect - and when he finds his men wiped out and the Vietnamese gang responsible for it nearby, he rushes into the fray with a machine pistol and guns down everyone he can find, all the while shouting things like "Your blood will flow like wine!" - all this despite the fact that he's blind.
 * Fallout 3 has the Nerd Rage! character ability, which requires a certain minimum intelligence score and points invested in the "science" skill. When your character's health drops below 20%, his strength stat is maxed out and damage taken is halved.
 * Yo-Jin-Bo could arguably apply this trope to all the guys except Ittosai. However, special mention must be given to both Bo, the highly chivalrous Bishounen fond of kissing your hand, and Mon-Mon, the goofy monk.
 * In Fire Emblem: Shadow Dragon, one of the few recruitable party units to attack you unprovoked is Wendell, the bishop who looks like the freaking pope. His dying quote mentions he has "no love for war", but you may remember that he's one of the only recruitable units who attacks unprovoked. Others include Roger, a hapless conscript who couldn't care less about war but doesn't have anything else going for him, and Jake, a gleeful ladies' man. Compare these with Darros the ruthless pirate and Navarre the stoic hired sword, who both try to talk to Marth or Caeda as soon as possible.
 * Occurs again in Path of Radiance and Radiant Dawn. Ilyana, a weak thunder mage will try and kill you if you don't recruit her first. Mia, a nice swordgirl, can easily become the most competent sword-fighter excluding Ike. In Radiant Dawn, the main character is a nice, quiet light mage who can sacrifice her hitpoints to heal others.
 * Played with in The Sacred Stones in regards to Cormag. His supports show that he's a really nice guy, but he's beyond enraged when he meets the heroes, because he thinks they killed his brother.
 * Any good-aligned character in Fable games. In the second outing, and with enough experience, they will not hesitate to kick enemies in the face before chopping their head off with an enormous meat cleaver, knock them off of a cliff, shoot them in the crotch, knock their silly little attack aside and bash their heads in for their troubles, and all manner of other cruel applications of death and dismemberment. Probably while on their way to rescue slaves, collect on a bounty, or just give money to the church.
 * With the exception of Blue in Pokémon Red and Blue, every single Pokémon League Champion is perfectly friendly to the player in the field, then they clash for the title and pull out their team of Pokémon 15-20 levels higher than your own, all pumped up with the strongest moves they can know.
 * In Pokémon Gold and Silver, Gym Leader Jasmine is first seen literally having abandoned her post to take care of a sick Pokémon at the Olivine Lighthouse. She is also incredibly shy. Some more gameplay later, you get to fight her...and one of her Pokémon is a Steelix.
 * Also in Generation I, Red was a quiet boy who exemplified how important it is to care for Pokémon. After spending three years in Mt.Silver? Strongest trainer of the entire series.
 * Many Pokémon themselves also fit, like the sweet and innocent Togepi, who grows up into Togekiss who has the second-highest Special Attack of any Normal-type Pokémon. For a point of comparison, a Hyper Beam used by Togekiss is just as powerful as a Hyper Beam used by Arceus. And the Pokédex describes it as a harbinger of peace and goodness!
 * Cubone. Fridge Logic aside, there's a story of one that had its mother killed by Team Rocket. It picked up her skull and one of her bones and swore revenge. It doesn't help that back in the generation it was introduced, its evolved form could increase its Attack stat while attacking so much it would overflow. Did I mention is a small, lonely Pokémon hiding inside an oversized skull?
 * James, the God of Earth in Sacrifice, is very down-to-earth, stressing pacifism or diplomacy for the first half of the game. Later, when it becomes obvious that warfare is the only option, he grants you a few useful tricks if you're his follower. Tricks like the power to make entire sections of the world fall into the abyss.
 * Earthworm Jim brings us Peter Puppy. At first, he seems like a cute little puppy. But if you dare piss him off, he will turn monstrous and beat you up For Massive Damage.
 * Baten Kaitos has Lyude's finisher, Sforzando, which is based on this. The game describes it as Lyude "giving in to his rage, usually kept in check by rationale." What you see is Lyude leaping forward and viciously pistol-whipping his opponent so hard he actually staggers backwards when he's finished.
 * And from the prequel we have not just an attack, but a character who plays this trope fairly straight: Sagi is an Adorably Precocious Child who is a major Momma's Boy and does pretty much everything to get money for her to run the orphanage back in his hometown. He even takes most of the villains' actions in stride and stays pretty upbeat and friendly while they're off wreaking havoc. Push him too far, however, and nothing will stop him.
 * Who's the killer in Heavy Rain? It's not, it's not  , and it's not even  . It's  
 * The Liir from Sword of the Stars are mainly kind, understanding Actual Pacifists. Until you piss them off. We'd call in the survivors of the last race to piss off the Liir as witnesses to this, but none appear to be alive as the Liir wiped them off the face of the Galaxy . In-game, the Liir start out extremely positively towards all races except the Zuul and are very easy to placate as long as you keep the peace with them -- but if they first get annoyed enough at you to start a war, you'll never get them to back down again: They'll come at you until you or them are dead.
 * The majority of Lux-Pain cast. Once they're infected with SILENT, you better look out.
 * Mike Haggar, Mayor of Metro City. Kidnap his daughter, and fear his pro-wrestling skills.
 * Super Smash Brothers Brawl showed that should the normally chivalrous but calm Link or Mario mistake you for severely harming their beloved Zelda/Peach, you will either get a sword or fist plowed into your skull. Based on their track records, you're more likely to survive the sword.
 * in Rule of Rose. Also the protagonist Jennifer, herself. She may be meek and submissive and faint easily, but if you push her around long enough, she will push back with strength that terrifies the entire Aristocrat Club.
 * Link The Legend of Zelda is an example in nearly all of his incarnations. He's polite, humble, good with kids (unless of course his current incarnation is a kid), and often Adorkable. He's usually a Farm Boy, a blacksmith's son, or something equally quiet and peaceful. He's just generally a nice guy. Until you hurt his little sister. Or the village kids. Or Princess Zelda... Or whoever his Implied Love Interest is this week. First he'll ask politely for you to give them back. If you refuse, then he'll just fucking stab you in the head. (Warning, major Wind Waker spoilers.)
 * The title character of Klonoa. In the first game, he's a really nice, fun-loving Kid Hero. He even borders on Cloudcuckoolander occasionally. Then  did NOT survive the next level.
 * Spiritia Rosenberg of Rosenkreuzstilette counts for this trope as well. Despite being naive as well as a terrible swimmer, she's generally a nice girl with moral convictions that are second to none. Then her colleagues start a war against the Holy Empire to build a world just for Magi, all the while burning down the forest that was home to the fairies and where Tia was training at for six months for that in the process. Her response? Plow her way through dozens of monsters, demons, and The Undead and battle and defeat her colleagues themselves in a Swiper, No Swiping deal to get them to listen to her and follow her ideals, all leading up to Graf Michael Sepperin himself. But, she doesn't even know that.
 * Wheatley from Portal 2. Normally he's a rather friendly yet dim-witted robot who tries to help you escape from the lab. That is, so long as you don't call him a "Moron". Do that, and all hell breaks loose.
 * Garlot, protagonist of Blaze Union, is gentle and empathetic to a fault, and even though he has a short temper, he generally cools down very fast. He has self-confidence problems and spends a lot of his downtime wishing that everyone would just get along. And he's no pushover normally. But when bandit-by-any-other-name Pandra decides to sack Garlot's hometown, he goes into a state of cold rage so terrifying that every enemy in his path basically shits themselves in terror. In addition to this, inflicting serious harm on the people closest to him is a really, really bad idea.
 * If Gandhi threatens you with nukes, listen to what he has to say.
 * The Psilons in Master of Orion are generally pacifistic and do not actively seek to conquer other empires. However, they have the best research abilities in the game, and will invariably be higher on the tech tree than you, which means they'll thrash you in a war.
 * Fallout: New Vegas has a few of these. On the Player's Team there is Veronica, a Brotherhood Scribe who wants them to play nice instead of raiding anyone with energy weapons but can also punch a deathclaw to death with her powerfist, Arcade Gannon, a Follower of the Apocalypse doctor and researcher who wants everyone to be happy but is also  well trained in Energy Weaponry, and ED-E, an eyebot that just wants love and to find a home. Cass could also count, but she's an example of Good Is Not Nice.
 * There's also Christine Royce, a deeply philosophical Brotherhood of Steel Scribe who was Veronica's lover. When their former elder, Elijah broke them up, she joined the Knights and the Circle of Steel. When she heard about Elijah murdering people all over the wastes and abandoning the BOS at Helios One, she volunteered to hunt him down and assassinate him, becoming one of three people to explore the Big Empty and escape before assisting the Courier in killing Elijah and becoming treated as invulnerable as the security holograms to the  Ghost People.
 * There's also Marcus and Mean Son of Bitch, two very friendly Super Mutants. Marcus, however, was a player companion in Fallout 2 and helped blow up the Enclave's Oil Rig and Mean S.O.B. defends Westside against the fiends so well that most of them stay away from Westside now.
 * Most of the low-level NCR troopers and Rangers can be seen as this. Most of them are nice gentle people, but they can kick your ass. Special note goes to Private O'Hanrahan, who doesn't want to kill people but in certain endings helps assisting his squad single handedly stop a Legion assault on NCR Ranger HQ at Camp Golf.
 * Beware all the nice ones in Nine Hours, Nine Persons, Nine Doors. In particular, hurt either of the affable and helpfully sharp Brother-Sister Team of Snake and Clover and the other will rip you to a ragged pile of shreds on the spot; bumbling Big Guy Seven is ; soft-spoken, peaceful, cute-as-a-button Love Interest June  ; and even jokester everyman protagonist Junpei is quite an expert Guile Hero when he needs to be.
 * Avion from Shadow of the Colossus is generally considered the second most peaceful colossus in the game, by virtue of the fact that it will never attack Wander until provoked. Until Wander makes an attempt to harm it, Avion is content to sit on its perch and watch him swim around the lake... but the second Wander shoots an arrow at it, Avion will come swooping down to divebomb him. This attack is a one hit kill in Hard mode if Wander is not successful at dodging it, and is pretty damn scary otherwise.
 * Luigi is generally a pretty nice guy. If you threaten to harm Mario, he becomes an unstoppable force.
 * Noel Vermillion of BlazBlue. Her hobbies include shopping via the internet and writing poems. She likes cute things, and dislikes bugs, especially ones with lots of legs. Then you think about her true form,
 * Makoto Nanaya is a silly, friendly, generally whimsical and energetic person, and also appears to be somewhat scatter-brained. However, she makes it clear to Tager, "If I find Noel Vermillion is hurt or harmed in any way, I will find that person and make them pay. Dearly."
 * Every Nancy Drew game ever.
 * Golden Sun has a few nice ones to beware:
 * Ivan in the first game. Sure, he has his moments of Mind Over Manners, but he's otherwise a sweet and thoughtful little boy who is good with people. Then he finds out his foster-father is being held hostage in the local Wretched Hive with the intent of extorting his hometown, and just about rips the place apart to save him.
 * Mia. The demure Staff Chick? In The Lost Age, Agatio is more afraid of her healing and type advantages in combat than he is of Isaac.
 * Dark Dawn turns this into an entire gameplay mechanic during the battle with the Bonus Boss Ancient Devil. Devil's gimmick is that he can brainwash one of your player characters into assisting him. And he's programmed to identify player characters most advantageous for him to do this to. All the buff, aggressive heroic guys are his last picks because of their lesser power selections. His number one target? Shy, sweet Sveta Czamaral. And if he gets her, she will take out at least half the party. Expect a full-fledged TPK if she's in Beast Form at the time.
 * Aqua in Super Bomberman R is a hardcore pacifist and tries to talk Magnet Bomber and Red out of fighting, and gets yelled at and punched out of the way by Magnet for her attempt. She gets so furious that she uppercuts them both into the stratosphere. Red's panicked reaction when Magnet punches her, as well as Pink's and Black's remarks after the fact, imply she is known for such violent outbursts when pushed too far despite her usual nonviolent disposition.
