while this character does originate from a manga and there is a strict "video game characters only" rule, hear me out here: jojo's bizarre adventure owes its entire popularity in the west to video games. without capcom's fighting game adaptation of the manga, part 3 (where this character originates) would never have gotten an official english translation. due to this, i believe jotaro can be considered a "video game character" as much as he is considered a "manga" and now "anime character".
jotaro is easily the most visible protagonist in jjba, appearing prominently across 4 of the 8 story arcs that make up the series. a former high school delinquent of the legendary joestar bloodline, jotaro would offer something completely unprecedented in a smash environment - the powers of his stand, star platinum, which possesses superhuman strength, speed and precision.
stands are too complicated to explain within the confines of a brief persuasive forum post and i'm super lazy so have a wiki link: http://jojo.wikia.com/wiki/Stand
anyway yeah
if this is against the rules, notify me and lock the thread.
