Monoculus is an enemy of the Ninja Turtles. As a flying alien eyeball from the same comic book as Wingnut and Screwloose, he is the supreme ruler of all the floating eyeballs. He was brought to the real world by April's Aeon Crystal, but then it was killed by April O'Neil when she used her psychic powers to kill the alien with her Tessen. Monoculus debuts in Bat in the Belfry.
