"Evil Ryu" and "Oni" Unlocked in Super Street Fighter IV
Super Street Fighter IV has only just hit arcades, but two new characters have already been unlocked by players. Evil (or "Shin") Ryu, as first seen in the Street Fighter Alpha series, and Oni, some sort of variation on Akuma with white flames for hair.
All known videos of the two characters in action have been removed from YouTube due to a copyright claim by Capcom, which is...strange. Why cover something like this up?
Capcom has still not said one way or another if it will be bringing these new characters to the console versions, but they'd only be angering fans if they didn't.
