Street Fighter tournaments are serious business ... case in point, this video of Kenny Omega superkicking the crap out of a John Cena wannabe Friday during a competition.

The Cleaner came up short while facing off with another tournament participant in Orlando at CEO 2016 -- a popular fighting game competition -- and afterward, attempted to bow out peacefully.

Only problem, the next entrant came to the ring dressed as John Cena.

We don't wanna spoil too much ... but just know this gamer doesn't have the same morale compass as the 15X time champ, and Kenny is forced to teach him a lesson.
