Name of Cain

""C-a-i-n, like in The Bible, but I didn't kill anybody.""

- Herman Cain's typical self-introduction.

Ever since that guy in The Bible killed his brother, characters named Cain, Caine, Kane, Kayne, or variants, have had a bad reputation. They tend to be villains. Since Evil Is Cool, though, it was only a matter of time before the name became acceptable fodder for the odd Anti-Hero, as well. Either way, they tend to be morally sketchy, and probably badass.

A specific form of Name From Which To Run Away Really Quickly, and, of course, a Meaningful Name. Also see Cain and Abel, for obvious reasons.

Anime & Manga

 * The villain of the first Tenchi Muyo! movie is named Kain.
 * Cain in Trinity Blood. In this case it's a direct Bible reference, as his "siblings" are Abel and Seth.
 * Also, Kane/Kain Blueriver from Lost Universe. Much better name than "Shining Greenriver" (Hikaru Midorikawa)
 * Cain in Nightwalker.
 * Kane from Beyblade, at first glance, seemed to be an aversion to this trope, being a sociable and helpful team leader who easily befriends Takao. Then he goes Brainwashed and Crazy...
 * Cain of Count Cain/Godchild. While he's actually the protagonist, he was given the name because his father believes him to be cursed. He has a troubled past, is known as a ladies' man, collects poisons for a hobby, and has the unlucky tendency of having the people around him die often, and in gruesome ways.
 * However, Alexis reveals that he named his son "Cain" because even though the biblical Cain committed a terrible sin, God still forgave and protected him, and eventually allowed him to settle down. An oddly touching interpretation from a guy who's otherwise a Complete Monster.
 * Golden Cain. The title refers to the main character's enigmatic love interest who's trouble, to say the least.
 * Teknoman, the US adaptation of Tekkaman Blade, renames Evil Twin Shinya Aiba into Cain Carter... possibly to make up for renaming his tekkaman form to Teknoman Saber instead of the extremely descriptive "Tekkaman Evil".
 * The name Cain actually makes sense here, though: Based on the flashbacks, it seems that the twins' incredibly screwed up parents had been intentionally goading their sibling rivalry into full blown homicidal malice for pretty much their entire childhood, before anyone had ever heard of a tekkaman.
 * The Trigun anime used a guy named Kaine the Longshot to replace a less family-friendly villain in the manga version.
 * Sergeant Cain Fuery of Fullmetal Alchemist. Subverted in that he's a rather shy and somewhat geeky communications officer.
 * Word of God says that the author picked most of the first names for more minor characters at random from a dictionary of European names.
 * It's actually a misromanization of Huey, after the iconic helicopter, as part of the military characters' Theme Naming, all of them being christened after military aircraft. Huey Kane does sound a bit more fitting for the character.
 * Variation: In To Aru Majutsu no Index, the main character's name is Touma. From Toma/Thomas the Unbeliever. Who can erase anything related to God. While led him into this trope, through the in-Universe Fridge Brilliance of a character who suggested
 * Prince Cain from Reimei no Arcana. He is Caesar's older half-brother and the first-in-line to the Belquat throne. However, he holds a strong hatred for Caesar as Caesar's mother was put as queen while Cain's mother was dethroned, Caesar has black hair (hair color is taken as Serious Business with black hair being the most favorable while the rest of the hair colors are seen as "common"), and Cain's fiancee Louise has feelings for Caesar.

Comic Books

 * Kathy Kane, the original Batwoman, and her niece Bette Kane, Bat-Girl. Unambiguously heroic, but usually treated as pests or second-raters by Batman, whose mother's maiden name also happened to be Kane. Probably named after Batman creator Bob Kane, who appears not to have been a real-life example of this trope. Maybe. The current Post-Crisis Batwoman, Katherine "Kate" Kane, has been drawn into the inner workings of the Religion of Crime due to her presence at the heart of their prophecies regarding the "twice-named Daughter of Cain". As a "twice-named" (referring to ) and the daughter of a "Kane," the religion has become somewhat preoccupied with her sacrifice.
 * Cassandra Cain, the second Batgirl, is usually heroic, but has some trauma to her backstory. Her father, David Cain, was an assassin.
 * X-Men has Cain Marko, The Juggernaut, BITCH!
 * Even more appropriate given he's Xavier's older, stronger, bullying stepbrother, jealous of his brother's intelligence and family favor. If you're still not convinced, flip his names around.
 * Kaine from the Spider-Man Clone Saga. Being an unstable, overpowered psycho clone who simultaneously loves and hates Peter Parker (and Ben Reilly) is pretty fitting here.
 * Killer Kane from the Buck Rogers cartoon strip.
 * Cain was the sinister trickster host of DC's horror anthology series House of Mystery; his brother Abel hosted its sister series, House of Secrets. While originally the names weren't strictly meant to say that they're the Cain and Abel, their appearances as supporting characters in The Sandman established that they were anyhow.
 * Well, sort of. Actually it's implied that they're really a pair of Starfish Aliens from billions of years ago who were the first sentient lifeform in the universe to intentionally kill another of its own kind and its victim. The first act of murder was so monumental that they became archetypes living on for all of history in the collective unconscious of all life, perceived by each new observer as one of their own and inspiring stories such as the Bible story of Cain and Abel. It's interesting to note that while Eve is also a character in the comics, she does not consider herself to be related to them and denies it when Cain calls her "Mother". Cain responds that she is "everyone's mother", and leaves it at that.

Films

 * Citizen Kane's Charlie Kane is definitely an Anti-Hero.
 * RoboCop 2: the drug lord (torturer, murderer) Cain.
 * John Lithgow's character from Raising Cain.
 * Doomsday has the Mad Scientist Marcus Kane, and his Ax Crazy son Sol... whose full name is presumably Solomon Kane.
 * In Southland Tales, Boxer's screenplay centers around a character named Jericho Cain (who he hopes to be able to play himself).
 * Gabriel Caine in Diggstown, while a con man, is basically good and is an unambiguous hero of the story.
 * Sutter Cane, from In the Mouth of Madness, is an horror writer whose latest novel would have disturbing consequences. Seems to be more an allusion to Stephen King than to Abel and Cain, though.
 * Alien: Kane was the crewmember who "gives birth" to the terrifying xenomorph.

Literature

 * Subverted in The Kane Chronicles by Rick Riordan.
 * The Jeffrey Archer book Kane and Abel, although Abel wasn't portrayed as the "good" one.
 * Solomon Kane, Robert E. Howard's swashbuckling Puritan hero.
 * Karl Edward Wagner's Kane, who is in fact a Conan-esque (that's the description for those who have never read the Kane books... he's actually not much like Conan at all) version of the Biblical Cain, with stories that take place in a dangerous and dark prehistory. Kane himself was cursed with immortality by an insane elder god after having strangled his brother, Abel.
 * From the evidence given in the stories, it's pretty clear that the insane elder god is meant to be Jahweh, ie: God
 * From The Bourne Series, Jason Bourne's codename in the books is Cain, and . Also, in the movies, an alias of his is John Michael Kane.
 * Caine of Garthan Hold (aka Hari Khapur Michaelson), of Matthew Stover's The Acts of Caine, who definitely has the morally ambiguous Badass anti-hero thing down pat.
 * Ciaphas Cain HERO OF THE IMPERIUM!!!, a Fake Ultimate Hero, has not one but two names with unfortunate Biblical implications. He doesn't have any siblings, though.
 * Well not with a name like that he wouldn't.
 * The, Caine, of Michael Grant's Gone (novel).
 * The Ellery Queen novel "The King is Dead" features rich munitions maker King Bendigo, his wimpy brother Abel, and his drunk brother Judah. King Bendigo's real first name is Cain. He's the Big Bad.
 * The Caine in The Caine Mutiny. Tom Keefer even specifically says he feels the ship, a WWI relic held together by rust and grime, is as detestable as its Biblical namesake.
 * Valkyrie Cain in Skulduggery Pleasant is one of the good guys, but she specifically picked her name based on the expression 'raising Cain' (making trouble).
 * Subverted by Robin Kane, who is a teen girl detective, sort of like Nancy Drew.

Live-Action TV

 * Duncan Kane (and his morally dubious dad Jake Kane) from Veronica Mars.
 * From Battlestar Galactica, Admiral Cain of Battlestar Pegasus, as well as Commander Cain.
 * The villain in the Doctor Who story "Dragonfire".
 * In the short-lived TV series Kidnapped, Cain is the name of the family of the kidnapped boy, who are embroiled in all sorts of conspiracies and nastiness.
 * An interesting example here is Kwai Chang Caine from Kung Fu - generally a good guy, but not wholly unlike his biblical namesake; he killed a man and had to leave his homeland because of it.
 * Horatio... Caine of CSI: Miami.
 * Wyatt Cain from the Sci Fi Channel's Tin Man, and the Tin Man in question. All around Badass Normal, ex cop and ready for vengeance. But only against the people who destroyed his life and killed his wife and son (he believes).
 * Adam Kane from Mutant X.
 * Evil, evil Cain Dingle from Emmerdale.
 * Erica Kane from All My Children is generally at worst, a vindictive matriarch you don't want to mess with.
 * Gib Cain the werewolf hunter in Buffy the Vampire Slayer, who doesn't care his victims are human 25 days out of the month.

Professional Wrestling

 * Kane of the WWE. His backstory is that the seven foot tall monster was burned as a child and raised by "manager" Paul Bearer, he is also brother to The Undertaker. Although both are dark and evil characters, the biblical brother theme is still present. And then there's the whole "sadistic pyromaniac" aspect of his character, which makes him seem even more demonic. He has since suffered some character decay, according to some.
 * The Undertaker actually debuted as "Cain the Undertaker", although he dropped the Cain part after a few months.
 * Multiple independent wrestlers have used variously spelled versions of the name Damien Cain.

Tabletop Games

 * In the Vampire: The Masquerade, the biblical Cain (here spelled Caine) was the very first vampire.
 * Warhammer 40,000 plays this one straight with Khaela Mensha Khaine, the Eldar god of war. In Warhammer Fantasy Battle, he's the God of Murder.
 * To the Dark Elves maybe, the High Elves still consider him to a God of War, just one that you don't turn to unless you need to.
 * Also subverted with Commissar Ciaphas Cain (HERO OF THE IMPERIUM!), the hero of the eponymous book series. He's a self-professed coward who gets by with a lot of luck, however, he's still plenty Badass and has taken on some of the worst the galaxy has thrown at him and come out on top on most occasions.

Theater

 * Sera Myu has Cain the Dark.

Videogames

 * The Legacy of Kain series stars a vampire named Kain, who later goes on to conquer the world, lead it into ruin, execute plan after plan to save it... Kain's not a nice guy, but he doesn't start off evil and it's indicated that he doesn't end the series all that evil either. Still not nice, but...
 * Possibly parodied in the obscure SNES game The Twisted Tales of Spike McFang, in which the first boss, Cane, is literally a cane. Like, a walking stick. You have to fight a walking stick.
 * Lucas Kane, protagonist of Fahrenheit (2005 video game), spends most of the game on the run from the cops after killing a man. Admittedly, he was possessed at the time, but still.
 * Kane from the Command & Conquer: Tiberium series, the Dark Messiah of the Brotherhood of Nod, is heavily implied to be the biblical Cain - he's certainly been around long enough, and in Renegade the player can find Abel's tomb beneath the Temple of Nod in Cairo.
 * Mega Man X series' Dr. Cain isn't a bad guy, but his attempts to copy Dr. Light's research has ended in disaster. (Guess Dr. Cain forgot about the whole "30 years of brainwashing--er, I mean, ethical training".)
 * Kain of Final Fantasy IV, complete with feeling jealous and overshadowed by his brother-figure Cecil. Golbez takes advantage of this.
 * Cain from the original Fire Emblem subverts this, acting as one of Marth's earliest and most staunch allies.
 * That's a relief. I always kept killing him off for fear of betrayal.
 * And to add to the irony, it's Abel who betrays his kingdom in the sequel.
 * However, the instant Est is safe from harm, Abel joins your side again.
 * General Thaddeus Kaine of Zork Nemesis.
 * In the NES version of Strider, one of the supporting characters is named Strider Kain. Strider Hiryu is sent to kill him because he's fallen into enemy hands (Striders caught by the enemy are considered expendable since their identities are now known), but the situation becomes more complicated than it seems.
 * Xenogears has an Emperor Cain. And an Abel, no less! The game's filled with Biblical references, after all.
 * The Kane family of the Twisted Metal series is one Big Screwed-Up Family. "Needles" Kane is a Monster Clown/Serial Killer, Charlie Kane is a reanimated corpse being controlled by his son, Marcus Kane is insane, and it's implied the entire series takes place in his head.
 * Adam "Kane" Marcus from Kane and Lynch.
 * Subverted in the Diablo series. Deckard Cain is a Last of His Kind scholarly good guy who will identify your magical items for you.
 * Lord Kane from the original Shining Force.
 * Kainas Christi from the obscure Kartia: The Word of Fate, father to Lacryma, one of the two protagonists.
 * Billy Kane from the Fatal Fury and King of Fighters games, though in this case his surname is pronounced "Khan".
 * Kain R. Heinlein, also from Fatal Fury. Best friend to Abel "Grant" Cameron. You see where this is going right?
 * Not a character example, but the M-920 Cain is the most powerful weapon in Mass Effect 2. One shot will kill almost any enemy in the game, and the final boss can only take two hits. It has two drawbacks however: a long charge up time and a blast radius large enough to easily kill the player.
 * An alchemist named Caine appears as a ghost in Ultima VII on the now-dead island of Skara Brae. He blames himself for this, as he attempted to make a substance that could kill the lich Horance who was taking over the island, but botched the mixing process which resulted in a colossal fire that destroyed the island.
 * Cain in Galerians is a textbook example of this, being a jealous, villainous, and murderous brother.
 * Cutter Cain, who kills Seers, typically with a knife, in City of Heroes : Going Rogue;
 * A character named Caim (a Gaelic spelling of Cain) is the main character of Drakengard. His moral compass can be described charitably as "Anti Heroic"—in fact, the only thing that keeps him from being a Villain Protagonist is that the target of his Roaring Rampage of Revenge happens to plan to Take Over the World (and for the record, Caim would still be butchering them all even if their goal happened to be 'build the world's happiest puppy orphanage').

Web Originals

 * Grandmaster of Theft focuses around protagonist Cassidy Cain, an Anti-Hero Classy Cat Burglar. Furthermore, she's a member of the Cain Dynasty and family founded CAINternational.
 * What SCP-073 calls himself. Ironically he's a pleasant Walking Wasteland while "Able" is an Ax Crazy Blood Knight. Professor Crow's first name is also Kain.
 * Warrick Kaine, aka Alloy from The Descendants.
 * Kain, evil Dragonstorm leader from Darwin's Soldiers.

Western Animation

 * In the Comic Book Within A Show Radioactive Man, Radioactive Man's Secret Identity is Claude Kane, probably in parody of this trope. He's depicted as pretty much an Idiot Hero.
 * Dragon Booster has a character named Cain, played of course by Scott McNeil.
 * Episode 11 of Sym-Bionic Titan has Lance and Illana escaping a mysterious prison with a fellow prisoner named Cain. He's actually a good guy...until he turns out to be The Dragon of the bad guys.
 * Abraham Kane of Motorcity, the show's Affably Evil Big Bad obsessed with crushing what little population of Detroit remains outside of his rule. He even has a fitting voice, being played by Mark Hamill.

Real Life

 * Michael Caine, best known for playing Lovable Rogue type characters. It's a Line-of-Sight Name. He was originally going to change his name to Michael Scott, but that name was taken, and he happened to spot an ad for The Caine Mutiny. He has joked in interviews that had he looked the other way, he would have ended up as "Michael One Hundred and One Dalmatians".
 * John McCain, and many other permutations of the name. However the source of the name is believed to be Gaelic words that actually have nothing to do with the Biblical Cain.
 * Mixed-martial-artist Cain Velasquez is in the unusual position of having the given name Cain. Velasquez went in the opposite direction entirely with his daughter's name, Coral Love Velasquez.
 * CDNS CEO Paul Kane, who now owns one of the seven master keys to the internet. Make of that what you will.
 * Bob Kane, the man who co-created Batman.
 * Herman Cain, a former 2012 Presidential candidate, seemed to like poking fun at this.
