Name: Char Tsumi
Nickname(s): "Just Char's fine"
Age: 19
Gender: Male
World: Pokémon
Species: Charizard/Human Hybrid
Appearance:

Personality: A simple rundown, Char is typically very chill and relaxed, unless provoked like the hot head he is, and gets excited when he hears about a strong opponent. He loves to battle for the sheer joy of it, and refuses to be called a lizard.
Abilities/Powers: Just as you'd expect, he knows several Pokémon moves and a abilities, including Fire Punch, Dragon Claw, Shadow Claw, Flamethrower, Blaze, Tough Claws, and Power Boost. His three abilities are separated by his three forms, normal, Mega X, and Mega Z. As powerful as he is though, he has one enormous weakness. If he can't finish a fight quickly, the power drains him immensely, most likely resulting in blackout.
Backstory: Char's backstory is far too long to tell in one go, so here's a simple background check. Char has a little sister named Eve, a father named Coal, a best friend named Geo, and a girlfriend named Sasha. His mother is in fact dead. He lives in Lumiose city, and his home is riddled with portals. He HAS in fact met both of the AU variants before, but sees them only on occasion.

AU 2's Name/Nickname: Dark Char or D.C.
AU 2's Appearance:

Other: Chara, unlike Char, specializes in ranged attacks and prefers her Mega Y form over the Mega X form. And D.C., while much stronger than the other two, he does not possess a Mega Z form. All 3 of them do actually have their own preferences in day to day things like drinks, foods, fashion, etc.
