Pro tip: Metal Man is a pushover

Part of the fun of the Mega Man games is getting the special weapons from the rogue robots and then finding out which weapon does the most damage to each one. Mega Man 2 takes that to the extreme.

Toward the end of the game you have to fight all of the Robot Masters again, even though you've already beaten them once. And that means that you could use their own weapons against them. This doesn't usually do a whole lot... until you get to Metal Man.

Once the battle starts, throw one of his own Metal Blades back at him.

If it connects, BOOM!

Easiest fight in the whole game! Heck, easiest fight in the whole series!

Which is a pretty big reprieve after you've battled your way this far into the game.
