The duo helped subdue the Turtles to be placed in Karai's traps during "The Fourfold Trap", also suffering a brutal defeat at the hands of Splinter when he came looking for his sons. In "Annihilation: Earth" Pt. 2, when the Triceratons came to Earth with the intention of destroying it, the two helped battle the aliens until Shredder doomed them all by killing Splinter. Terrified, the two embraced each other as they were sucked into the black hole generated by the Triceratons, making them among the first casualties of the destruction of the Earth. However, thanks to Professor Zayton Honeycutt reversing time back six months to before the events of "Annihilation: Earth", the duo were revived, and thanks to the Turtles of the future, the Black Hole Generator is stopped, before being destroyed, along with the Triceraton Mother Ship, by the Fugitoid in a kamikaze attack. Shredder is beaten by Splinter, and the duo are forced to flee Manhattan with the rest of Shredder's crew.
