Vega (Claw) is my favorite fighting game character, and his archetype is unique and perfect.
Spanish ninja bullfighter with a claw and mask and snake tattoo and roses? Yes please!
I know my least favorite representation of "Japan" is E. Honda, because he's pretty darn boring. He's so boring they put Kabuki makeup on so he wouldn't look like.... every other sumo wrestler.
Oh and my favorite representation of a weeb is Sodom from Final Fight/Street Fighter Alpha series. Guy is so funny.
