I'm glad that you brought my favorite ninja of all time into MUGEN (though that I prefer the Ryu from the hack-n'-slash version of Ninja Gaiden)
Which brings me the question, "Will the modern Ryu have different movesets based on Dead or Alive and the new Ninja Gaiden in order to distinguish from the classic Ryu?"
Remixing SSkye's Nostalgia Critic and AVGN in progress. Beta Release Dates......eh, maybe next summer or two. I dunno, could be before the end of the Earth or what the hell ever.
