Gaia Username: alyeth
Name: Cloud Strife
Age: 21 [That was his age in the game, and I know you said think more KH then FF, but what else am I supposed to assume?? xD]
Gender: Male
Height: 5'8" [He's really not that tall o.o]
Character Type: Fighter >=x
Occupation: He had signed a contract for Hades to kill Hercules in the Coliseum Tournaments, but afterward he left Hades and decided to go on his own. So currently his occupation is unknown.
Birth World: Ansem's World. [Where they had come from before that had been overtaken by the Heartless, I just played the game so.. xP]
Current World: Olympus Coliseum
Weapon: He has his powerful sword wrapped in bandages to decrease the pain contact, which is already ferocious and will leave you with massive bruises all over.
Personality: Cloud is rather the quiet type, he never really comments on things unless you approach him first. His evil aura gives off the vibe that he is perhaps on the Heartless's side or maybe just another 'bad guy' you must defeat, but in the facts, he's really just on his own side. He bothers no one really and keeps to himself. His demeanor can be intimidating, but overall he is very private and probably a nice person. I guess we'll never know.
History/Background: As in the game [which is what you said to go by] not much is known about his past, because he never talks about it and never discusses it. So nobody knows except for the people who knew him personally, and that is a mystery.

Other: (Ex: Likes, dislikes, etc.)
Obviously Cloud finds some amusement in fighting others, otherwise he probably wouldn't fight. He dislikes Hades, probably for not helping him, and maybe the Heartless for taking whoever it was away from him. But these are all just assumptions, as nobody actually knows.
Hope that's good ^^;;
