Age: 21; no time passes for him in camp.
Height: No canon, but roughly 5'11.
Weight: ...whatever's a reasonable weight for a fit, well-built adult male.
Medical Info: He's pretty normal. As a child and teenager he would have broken bones and whatnot, but nothing too serious. He's healthy and strong.
Eyes: Again no canon, but I'm saying dark brown.
Hair: Black.
Physical traits: Most noticeably, Fiyero is tattooed with blue diamonds. Since his canon is not in visual format, there's no real consensus on how these tattoos actually look. They are mentioned as being on his face, hands, lower arms and chest, and there's a suggestion that there's tattoos around his hips and groin too.
What's Okay To Mention Around Him/Her: Yero's aware that some people think he's fictional and that there are stories about his world. He knows he dies and he knows that Elphaba dies, and how she dies. Despite that, please do not mention [SPOILERS IN WHITE TEXT]:
-How and when, precisely, he dies
-His children's deaths/imprisonment
Please give me a headsup if you want to mention Elphaba's death or her being the Wicked Witch of the West.
Everything else should be okay. If in doubt, ask!
Abilities: Compared to most of camp, he is incredibly normal. He's reasonably strong and fit, has some skill with a spear, sword, hand-to-hand fighting and bow and arrow, but he is a pacifist and generally doesn't even defend himself when attacked. He has no special superhuman abilities.
Notes for the Psychics: ...most of the time he is probably thinking about Elphaba, his children, sex, or whatever looks interesting in the vicinity. He may be worrying about Elphaba, Glinda, Pellaz or Liir. He can't shield his mind, so feel free to read it. Ping me on IRC or via e-mail (in his profile) for specifics of what he's thinking at any time.
Can I shapeshift/bodyswap/spit at/step on/etc?: By all means, but ask first!
Kissing/hugging: Go for it! If it's romantic smooching and you are not Elphaba, please allow him a chance to dodge.
Maim/Murder/Death: Fiyero is, as already mentioned, an extreme pacifist. He would rather negotiate than fight. He will back off if threatened. If despite all of this your character still wants to hurt or kill him, talk to me.
Cooking: ...I really don't think so no.
