In the two-part season 3 finale, "Annihilation: Earth!" he briefly teams up with Splinter to stop a black hole machine that was to destroy the Earth. He briefly fought the Triceratons until he followed Splinter, double-crossing and stabbing him in the back, killing him instantly in front of the turtles. They rushed to Splinter while April blew Shredder away with a blast from her mind. Proclaiming that his victory over Splinter is more important to him than even saving the world, Shredder is sucked into the black hole along with his followers and Splinter while the turtles, April and Casey escape Earth's destruction and then in "Beyond the Known Universe", they travel back in time to six months earlier in an effort to prevent this event from happening. In "Earth's Last Stand" these events were revisited, but the arrival of the Turtles from the future resulted in Shredder's attempt to murder Splinter being thwarted. The two engaged briefly in battle with Splinter proving victorious, and the unconscious Shredder was carried away by Tiger Claw.
