Megaman 7 (SNES) - Final Boss - Dr. Wily (No Damage, Buster Only)

Hard. Very hard. Plain cruel. I will not write anything about the battle with Wily Machine 7 as getting hit there is quite difficult - so easy it is. But the perfect fight against Wily Capsule in this game is extremely hard to achieve. Especially with mega buster. Wily has only one attack (not counting the one with which he counter your shots) but it gives very little time to avoid and you must do it precisely as the slightest mistake will result in lost health.
