If it'd be your job to pick up a character or two from various mangas\animes and integrate them in one of the western comic book universes, who would you pick? Let's say you have to keep the character recognizable in regards of basic character traits and defining themes, but otherwise you can alter everything else in order establish the chosen character: back story, power class, etc.
My personal choise would be to put Majin Buuu from Dragon Ball Z into the DC universe.
A ridiculous goofball and a menacing monster at the same time, Buu would typically be something Mr. Mxyzptlk would create in order to test Superman's patience and nerves. His impressionability and gullibility could serve for some interesting moments: heroes being fooled by his infantile bahavior trying to convince him of becoming a good guy; villains manipulating him to do thier biddings (imagine someone like Toy Master having him as his personal army in exchange for sweets and playthings). Above all, his aforementioned personality quirks as well the absurd nature of his powers (turning people into candies, gaining the powers of others through absorbtion among his more converntional super strenght, speed and regeneration) could make him a perfect silver age tribute character, encompassing the era's campiness, monumentality and at times absurdity.
Well, that's my two cents. Who'd you guys pick?
