Megaman:
Small ,Kinda slow, not good jumper, but packs a punch.
Regular:
Shooting in all directions
Special:
Up:Item #1 from Megaman 2, but he automatically starts riding it
Down:Rain Flush and has a small radius around him.
Side:Charge Kick
Regular Special:It has a bunch of the powerups and it randomly chooses one.
Final Smash:He uses every powerup from every game all at once.
Cecil from FF 5 or 4 can't remember:
Medium, packs a punch, medium speed
