These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ryuhaku Todoh. Despite the fact that he only appeared in the very first game. However, thanks to his sheer popularity, he's among the newest additions of Capcom vs. SNK 2: Mark of the Millennium as a playable character, no less.
Eiji Kisaragi from 2. Highly popular among the fandom. When he returned to KOF in XI (after a eight-game hiatus), the fandom went bonkers.
The US version of Art of Fighting 2 redubs some of Robert's, King's and John's lines with English-speaking actors, and Mr. Big and Geese are voiced in English in either version. The problem is, nobody can act or kiai worth a damn. "Ha-HA! Piece of... cake!"
