The "hero" of CHR. Most of the story involves him killing things or gaining new powers, occasionally at the same time.
Anti-Hero: Type V. He sometimes fights evil people and isn't completely devoid of altruistic qualities, but he does far too many terrible things and enjoys causing harm too much to qualify as anything else.
Artificial Limbs: He gets a robotic arm in Part 1 after his first fight with Corrupted Blade. Shortly before that, the Magun fuses to one of his arms.
The Atoner: At times, as it's implied he turned himself in to the police out of regret for killing Soku and her loved ones, and he decides to atone for killing a dragon by bursting from his belly.
Killing Soku and all her friends and family because she turned him in to the police.
After he gets shot in the shoulder after accidentally teleporting to the Super Bowl, he kills 6 million people just to prove a point about how dangerous angry Horteka are.
Fan Nickname: "Vashblade" or "Bladevash" seem to be the most popular.
Friend To All Children: At times, shows a soft spot for children, like when he plays with some, but is not above killing them (like with Soku) or threatening to kill them (when he threatens to kill a boy if he reports his presence or if he does not bring him food while he's in hiding).
Fusion Dance: He can bodily combine with other characters to gain their powers, but he can also fuse his swords together, and later on he learns how to combine his various "sides" and their respective Super Modes.
Ultimate Blacksmith: In Part 2, he forges an Infinity+1 Sword that can split into three lesser swords. He also makes a device that can capture and convert rogue dragons, so he may have a Gadgeteer Genius streak as well.
Your Size and/or Weight May Vary: Infamously, he starts at 60,000 feet long, gets bigger, then inexplicably shrinks enough to fit inside a hospital or the co-pilot seat of a presumably small spacecraft. He's also stated to weigh 900,000,000,000,000,000 tons.
A nebulous force of evil with no clear goal besides possessing people and causing chaos.
Demonic Possession: Does this to Vashblade for a while in Part 1, though he eventually breaks free. It also possesses Spin off-screen.
In Name Only: Chaos in this story doesn't seem to be much more than a bunch of demons led by generic "dark gods". The traditional Chaos Gods aren't mentioned at all.
Unexplained Recovery: A common theme for the villains; they come back from being sealed, being totally destroyed and various other maladies several times each. Possibly lampshaded when Vashblade mentions killing a 'dark god' for the 900th time.
Corrupted/Chaos Blade
An evil(-er) version of Blade created by Chaos.
Blood Knight: He exists to fight and kill Vashblade.
Worthy Opponent: Vashblade enjoys sparring with him every once in a while.
Kekanu
A demonic being who first appears during the Ying-Yang War of Part 2. He becomes one of Vashblade's recurring foes, and the only one to die permanently before the climax.
Unexplained Recovery: In one case, he comes back barely a sentence after Vashblade specifically cut him up into pieces and destroys him completely. Also subverted, in that he actually dies.
A little girl that loves Vashblade for some reason. She may be the same character as a little girl who appears near the beginning of Part 1.
Love at First Sight: Assuming she's not the same as the other little girl, she just walks up to Vashblade one day and tells her to stop hurting his Evil Knockoff because she loves him. She regrets this later.
Stuffed into the Fridge: The little girl gets killed off by hunters, provoking Vashblade into killing them. Vashblade himself kills her two more times.
Unexplained Recovery: She comes back at least once, possibly twice if she's the same as the other little girl.
Arctic Wolf Tribe
A tribe of wolves who live in an extinct volcano in the Arctic.
