Stage: stage 3
This boss seems to be some sort of insect or crab. It can be seen moving in the background throughout the third stage of the game, but it cannot be attacked until the boss fight at the end. It first appears inside the building where the rest of the stage takes place. It puts down root-like appendages which attack by swelling and shooting fireballs. After taking some damage, the monster breaks free of the building and flies outside, where the battle continues. Here, it attacks by sending out smaller drones which attack the player with missiles. The monster itself does not attack here, and after the drones are taken out, the monster merely flies around until defeated.
