Plasmarine

is the OoA: of OoA:, the seventh OoA: in.

Characteristics
OoA: is a jellyfish-like creature that is battled in an underwater room, where OoA: is unable to attack using his OoA:. OoA: is susceptible to the OoA: and will alternate between its blue form and its red form each time OoA: uses the item on it. OoA:'s method of attack is to swim quickly to OoA:'s location, stopping briefly to either shoot an electric ball toward him, or try to electrocute him on the spot. The electric ball produced is always the same color as the OoA:'s present form; OoA: must use the OoA: to both displace the OoA: and switch its color, so that it gets hit by its own attack. As OoA: takes damage, it will begin to fire more electric balls in succession. After taking enough damage, it will be defeated, leaving behind a OoA: and opening the door to the OoA:.
