Mako Shark

From publisher blurb: "I Shall Rule the World beneath the Waves!" A disgraced Olympic swimmer who was turned into a monster by the fiendish Doctor Jeste, Mako Shark (PL 11) has abandoned the surface world to focus on conquering Atlantis, though he has yet to ever defeat it's rule, King Ravas. Mako Shark deigns to work with the Overlords because their leader, Haupman Klaue, promises that the group's victory will lead to Mako Shark's own aquatic ascension.
