bloodpack: Nosoul's answered your Q, but that "bug" is some type of graphical bug...

Your partner was a vip, but for some reason he appeared to be a reg. ryu. This appears to happen most frequently when you're using the download version and not hosting.

Trademarks: You'll see him using reg. ryu moves for those combinations which reg. Ryu has instead of Evil Ryu's moves (ex: air shinkuu hadouken instead of those "fireball" type things). However, for moves where reg. ryu doesn't have combinations (raging demon and those asura shifts), you'll see a reg. ryu color doing those.
