it would suck if "Megaman" was in the game, i'd atleast want his name to be spelled correctly (Mega Man) lol i wonder if they could get around copyright by calling him Megaman. Anyways heres some more featurees that are "too creative":
Up B: Rush Coil, this would also do some sort of uppercut for damage, or perhaps if you use it on the ground, Rush could run at ur enemys
Side B: I already explained my dream Side B in an earlyer post, basically you would have Mega Man steal a power from someone like kirby, but you would get a power from one of the mega man games, so if you steal from Sonic you get Quick Man's Quick Boomerang to use until you die or give it up by taunting.
B: Charge Shot, now you can either charge this (wich you can do while moving) or just spam it (like falco's laser, but weaker and you can do it while moving) the ability to shoot this while moving makes it strong.
Down B: Charge Kick, this move is from Mega Man 5 and its the same as Mega Man's usual slide move except it does damage. In Mega Man 5 you have to slide in order to activate this power, making it cool and unique. So its basically Mega Man's regular slide move, except it damages opponents (wouldnt be that good for KO power but would do multiple hits for building dmg)
A: a punch with his right hand
AA: a punch with his right hand, then left hand
AAA...: a punch with his right hand, then left hand, then he shoots his arm cannon weakly, the shots dispurst at a very short range
up tilt: and uppercut with the arm cannon (wich is his right hand btw)
side tilt: a more harsh punch with the arm cannon
down tilt: a sweep
Up Smash: an uppercut with the arm cannon that releases some energy to cover a short height
Side Smash: a swift blow with the arm cannon that releases some energy covering a short range
Down Smash: a powerful Sweep (like Samus')
Nair: a quick forward punch with his arm cannon
Fair: a side kick like Zelda's Fair
Bair: a longer kick like Sheik's Bair
Dair: Captain Falcon's Dair meteor, but weaker and faster
Uair: a backflip like Kirby/Captain Falcons Uair
Running attack: a slide move, like his Dwon B but better for KOing
Ledge attack: quickly gets up off the endge into a slide
I can't think of good throws atm, all i can think of are mewtwos throws so ill prolly edit this later
