Impact Man is one of the main bosses in Mega Man 11, almost like a robot version of sharp power tools.
My least favorite of the main bosses though. His attacks are hard to avoid unless you make good use out of slowmo in the Double Gear powers.
He got my health down far more than I would have liked it to be.
So I had to resort to using the acid barrier power which he is weak against. Which did the trick.
Once you beat him, you get the pile driver power.
Which isn’t that great to be honest. But whatever.
