MC may also refer to momentum cancelling or meteor cancelling.

MC was Isai Alvarado's clan in SSB64 online. Members included some of the top online Super Smash Bros. players in North America. Most of them can still be found in the Kaillera server Galaxy 64. Since Isai does not play online with the clan suffix "·MC" anymore, MC has become an inactive clan but many of the members still play without the tag.
