Street fighter Tournament (IC)
Ninjas and Superspies has an incredible number of systems designed to interlock and dance around, none of which are used to any effect whatsoever, and all of which, even if they were used, are obsoleted by having access to Butterfly Kick and a high PP score.
N&SS also lacks Hadokens.
I'd encourage you to look back at the Street Fighter RPG. It's surprisingly different from the core World of Darkness system, has a really unique combat system, and has all the Street Fighter styles and lore baked in. The out-of-combat stuff is typical WoD, but the fighting system is intricate, tactical, and full of flavor.
I'd really advise against using M&M, specifically because of the assumed scale. In M&M, it's really easy to accidentally make a character who can outrun a Ferrari, leap over a skyscraper, or punch a tank in half, just by taking relatively modest ranks in certain powers. Noncombat powers also scale up in size and scope very rapidly. It doesn't do that sort of... super-normal that Street Fighter characters usually represent very well, in my experience.
