Modified/Added and Subtracted.
MMA has restrictive rules and is a restrictive situation that forces a limited but new combination set of sport fighting methods. It's artificial, that's why nothing fits it.

Ray Butcher teaches Aikido usage for MMA but I think it's mostly for groundwork as I think most Aikido takedowns are illegal because of the rules about small joint manipulations and certain types of strikes. A kick is Savate, Hapkido. Krav Maga. I saw some spectacular types of TMA kicks take down opponents on some series broadcast from Japan.
MMA has little value for RBSD, street fighting etc or for general TMA benefits. Generally an entertainment, not worth bothering about in this field.
