Super Smash Bros. Wii U and 3DS Discussion

Megaman calling in his other forms is just pure fanservice. They won't be playable. It'll probably be like either pokemon trainers triple finish where they all launch a frontal attack together, or like falcons where it occurs purely in a cutscene.

We know for sure it involves that charged mega buster from all of them that we saw in the direct rather than any combo between the different ones though.
