When the entire population of Moonbase Bishop goes missing, it appears that Sh'Okanabo has jump started his plan to take over Earth. The Turtles stage an assault on the base, only to find a bigger, badder Sh'Okanabo, with an army of Kanabo Drones hiding on the dark side of the moon. Adding to the chaos, Darius continues to ruin the lives of the Turtles with his evil 'Dark Turtles' as he tries to take over Cody's company.
