The Shredder is back, and he's got some new dastardly plans. Meanwhile, the Turtles run into a lone Triceraton, who is stuck on Earth and has become delusional breathing Earth's atmosphere...
This episode provides examples of
- Chekhov's Gunman: Zog, who was only seen briefly in "Secret Origins Part 1", returns
- Genre Savvy: The Shredder realizes that Hun's plan to fool the Turtles into believing the Splinter-bot is the real Splinter will not work
- Laser-Guided Tykebomb: the Shredder's Splinter-bot
- Moral Dissonance: The Turtles find a Triceraton that was accidentally teleported back to Earth with them, a soldier named Zog. Since he can't breathe oxygen, he's delirious, and thinks that the Turtles and Splinter are commanding Triceraton officers. They save his life, but he's still delusional, and they wind up taking him on a mission to fight the Shredder. The fact that they knowingly and willingly manipulate a delusional alien by masking as his commanding officers, dragging him into a fight which is not his, and if he were aware of who they were would consider them enemies and want to kill them is never addressed.
