Leonardo, Raphael, and Michelangelo fought them only to be defeated since they didn’t have Donatello. However their plan was thwarted, when Donatello was able to convince the Triceratons that he was ruler of the Earth and the animatronic dinosaurs from the Natural History Museum were his minions. He also used Shredder’s powerful Micro Blaster to convince the Triceratons that he and his brothers were far superior to the Triceratons powers and abilities causing them to leave Earth.
