Age: He looks 12, but he's probably closer to 200. Canon doesn't say.
Eyes: Red.
Hair: Purple.
Height: In sealed form, 145cm. Short, anyway. In unsealed form, more like 180cm.
Weight: In sealed form, 45-50kgs. In unsealed form... 90-100kg.
Medical Info: DEMON. Other than that, Chrno is healthy and doesn't have any scarring. He regenerates pretty swiftly so he won't often be in the hospital. I have no idea if his inner workings are like a human's but I'll assume they're relatively close.
Physical traits: In sealed form, Chrno is a tiny boy. He has ridiculously long hair which is always done in a braid with a yellow ribbon. He looks MOSTLY normal except he has things like slitted pupils, sharper teeth and pointed ears so he doesn't entirely pass as human. Most people don't seem to notice this in passing. He doesn't appear to be all that strong but he is made of hardier stuff than you'd think.
When unsealed, Chrno is much different. He's
clearly a demon; he has batlike wings, long ears, yellow eyes, claws, a second spine coming out of the base of his skull with a RATHER SHARP POINTY BIT ON THE END, and he has metal clamps on his head that extend to some of his face where his horns used to be. His clothing also changes quite drastically.
What's Okay To Mention Around Him/Her: COPY PASTA FROM MY OLD ONE. Since I'll be taking Chrno from before the events in volume 5, please don't go telling him what's going to happen after that. If you've read it, you know it's not good :(. Also I'd prefer that no one mentioned Mary Magdalene to him, or anything related to her, without asking me first. Kind of a trauma button. Everything else should be fair game.
Abilities: While sealed, Chrno has the ability to ... get the shit kicked out of him a lot and not die. It's like his purpose in canon to be smacked around. He has faster healing capabilities than humans, so massive wounds will not hang around for as long. He has some minor powers he can use without Rosette releasing his seal, but they're pretty negligible and he tries not to use them.
Unsealed, he has quite a few abilities! He's very fast, capable of flying, and can naturally sustain about a million times more damage. He has claws that extend out of gauntlets on his arms which he can use to rip most things to shreds; he also has the ability to fire energy blasts out of his hands. As an idea of Chrno's power levels, he canonically lays waste to half of San Fransisco, picks up an entire trolley car and throws it at people, and can survive getting his arm, eye and wings ripped off, as well as getting a FIST punched THROUGH HIS CHEST. His powers are, however, reliant on Rosette unsealing him, and he can only keep them active as long as her watch is open. Or. If he's gone absolutely insane and has forced the watch open himself.
Notes for the Psychics: Chrno has a lot of terrible, terrible backstory angst. It stays mostly deep in his mind which is like a tomb, for serious. Also, Chrno is much older than he looks and thinks accordingly. Ping me if you want any more info on his mind because it's kind of a mess in there.
Can I shapeshift/bodyswap/spit at/step on/etc?: Go for it!
Maim/Murder/Death: Maiming is okay. Death is not. That would break the contract and hahahaha noooo.
Cooking: Well. He's better than Rosette. Not that that's hard to do.
