Cold Man's attacks?

[Mugendude26]

Alright, I'm making Cold Man for my Mega Man project that I'm working on however there are two attacks that he uses in Mega Man & Bass that I don't know how to code. The major one out of all of them is his Ice Wall attack. In the game, he summons a block of ice and pushes it against the wall where it bounces back and then breaks upon impact with him. How would I code that in M.U.G.E.N.?
