Bacterion is a boss in Mushroom Kingdom Fusion. The Mushroom Kingdom Coalition will find Bacterion in World 9, Edge of Beyond.


Bacterion appeared in Gradius III for the arcade and SNES, serving as its final boss. Contrary to the other foes in that game, Bacterion was weak with easy to dodge attacks, leading to it being taken down quite easily.


Bacterion was originally planned to be a world boss, but was demoted to a regular boss when World 6 was modified from its original SHMUPs plan.
