Destroying Special Attacks
Unlike in the original NES release of Mega Man, each Robot Master has their normal attack which mimics the original, and special attacks that are new to the game. These special attacks seem unavoidable, but you can actually stop them from executing these attacks by finding the attack's corresponding weakness.
For instance, you can use the Rolling Cutter on Bomb Man's special attack, the Hyper Bombs on Ice Man's special attack, and the Ice Slasher on Fire Man's special attack.
