Attacks and Strategies
Phase 1
Germ Shot: The boss shoots a small germ at the player which takes two hits to break. When it does this attack just try to dodge them by jumping on a trampoline or by jumping over them with an updash. Jumping over them and then hitting the boss is a good way to deal damage.
Germ Wave: The boss shoots a wave of Small Germ enemies at the player. When the boss does this attack the best way to avoid taking damage is to parry one of the germs as it is about to hit you.
Laser Beam: The boss will charge a laser for a short amount of time, then shoot it at your current position. It will do this multiple times before the attack ends. When it does this attack, try to get out of the way quickly because it shoots fast. Either try jumping on one of the trampolines, or go underneath to the other side of the arena. Right after the laser is shot is a good time to get damage.
Monster Spawn: The boss will spawn a Germ Monster beneath it which will remain in the fight until it is killed. Make sure to kill it as fast as possible, you don't want to worry about too many targets.
Phase 2
Phase 2 features all the same attacks as phase 1 but with a new one as well.
Laser Sweep: The boss shoots a laser toward one side of the arena, then slowly sweeps across the arena until stopping while underneath the boss. To dodge this attack, when you see the laser aiming toward the side of the arena, move to the other side while dodging the small germs.
Quad-Shot: The boss shoots four germ projectiles downwards. Try to position yourself between them, if one seems like it's on course to hit you, just parry it to avoid damage.
