Killraven is a Marvel Comics character created by Roy Thomas, Neal Adams, and Gerry Conway. He first appeared in Marvel's Amazing Adventures series in 1973, and has appeared in multiple alternate realities since then.
In the future of Earth-691, Earth was invaded by the Martians from War of the Worlds in 2001, who successfully conquered the planet and subjugated humanity. Post-conquest, men are used only for breeding or gladitorial combat, while women are used solely to produce children for the Martians to eat. After escaping from the games, former gladiator Jonathan Raven (dubbed "Killraven") joins the freedom fighters in order to search for his lost brother Deathraven.
This series contains examples of:
- Always Chaotic Evil: The Martians of Killraven's world are an Always Lawful Evil race.
- Ambiguous Disorder: Old Skull has a rather child-like nature and often refers to himself in the third person. It's unclear if this is due to some sort of mental deficiency or if there's some other factor at work.
- Barbarian Hero: Killraven's character design is more than a little reminiscent of a red-headed Conan the Barbarian.
- Cain and Abel: Killraven and Deathraven.
- Canon Immigrant: Killraven is eventually introduced in the mainstream Marvel universe, preceded by his mother.
- Captain Ersatz: Apeslayer, a character created for Marvel UK's Planet of the Apes title, is literally just Killraven with his serial numbers filed off. Strips from the Killraven series were even re-drawn and re-lettered outright.
- Cool Horse: The Serpent Stallion, Killraven's preferred mount of choice.
- Crazy Survivalist: Killraven and his Freedom Fighters, though the 'crazy' really only tends to come out in crossovers.
- Empowered Badass Normal: Killraven was already a deadly gladiator when he was brought to Keeper Whitman, who further enhanced his physical prowess and added in a few little extras to boot.
- Evil Counterpart: Deathraven, who was created by the Martians to... well, kill Killraven. He's actually Killraven's long-missing brother Joshua.
- Fantastic Racism: Killraven really, really hates Martians. It's not hard to see why, of course, but it does make him a bit intractable when it comes to exploring any other options in dealing with enemies other than Kill 'Em All.
- Fiery Redhead: Volcana Ash, the Freedom Fighters' redheaded ally, as well as Killraven himself.
- Gladiator Games: The Martians hold these and young Killraven comes of age in them, being forced to fight against other humans (including his own friends) for the amusement of his alien captors.
- The Grotesque: Grok, the deformed, ape-like clone of Carmilla Frost's father.
- Human Hard Drive: Killraven was secretly implanted with an encyclopedic knowledge of pre-invasion human history and culture. Unfortunately for him, he was never trained to access all that information at will, so it mostly comes up in unhelpful recollections or is spotty and incomplete.
- Les Collaborateurs: After finally meeting up with Deathraven, Killraven learns that Joshua has become a collaborator with the Martians.
- Lost Superweapon: Super is a bit of a stretch, but Killraven has a habit of picking up useful weapons from old destroyed museums, including his blue chainmail and proto-edged sword.
- Living Weapon: Killraven was turned into a living silver bullet against the Martians by Keeper Whitman, but most of his true potential is held back by a mental Restraining Bolt that Whitman didn't get around to bothering how to disable before being killed.
- Punny Name: One of Killraven's allies is a plant-human hybrid named Mint Julep. Another is named Volcana Ash.
- Psychic Powers: Killraven has weak ones that are attuned to Martian minds.
- Rated M for Manly: Part of the reason for the character's obscurity, sadly.
- Stock Ninja Weaponry: Killraven's not a ninja, but his most recognizable character design has a bandolier with star-shaped shruiken. He's quite handy with them.
- Survivalist Stash: The Freedom Fighters have these.
- Third Eye: Killraven has one, though he doesn't know it. He thinks it's a scar on his forehead as it's usually closed.
- Thou Shalt Not Kill: Averted: He's called Killraven for a reason.
- Zombie Apocalypse: The Martian occupation ends when Killraven unleashes a zombie virus among humans and human infants, effectively poisoning the Martians' food supply.
