The bosses in Flying Battery Zone require careful movement and timing due to the hazardous environment.
- Act 1: Heavy Magician: She teleports around and summons other Hard-Boiled Heavies in illusion form. Hit her when she's vulnerable after a teleport or attack. When she transforms, learn the attack patterns of the summoned Heavy and dodge accordingly until she reappears.
- Act 2: Dr. Eggman's Big Squeeze: A large crushing machine. You need to hit the red button on its side when it's exposed. Avoid its crushing attacks and the laser beams it fires. The arena has moving platforms, so stay agile.
These fights emphasize dodging and precise strikes.
