Rokko Chan joins the major crossover!! Rokko Chan is from a fan made game called Rokko Chan, http://king-soukutu.com/flash/rokko.html You can play it here! In fact, the game itself is probably the best OC Mega Man title out there, and fun part, it's actually really good! In MM X SSB, she will act just like Mega-Man, but with a few changes, for one, she can dash! Also, Rokko Chan is a girl, so there's that! lol But for real, I hope you all enjoy her and welcome her as a character!
