Teenage Mutant Ninja Turtles

The Turtles try to use fragments of the Vortex Crystal to stabilise their mutations, but Lord Dregg wants to use the fragments to construct another Vortex Crystal to power his Vortex Transporter.

Raphael, Michelangelo, Donatello and Carter work on restoring Leonardo to his normal self. Plus, Mung steals all the valuable plutonium from a power plant in order for Dregg to build a deadly plutonium ray.

Shredder and Krang are teleported from Dimension X to the Dreadnaught by the dangerous Lord Dregg, in order to learn more about the Turtles and Earth's weapons.

Dregg drains Krang's intelligence and the Turtles' life energy, planning to fire the vortex transporter at the sun. If the people of Earth refuse to surrender, the planet will become a second sun.

The Turtles of the past rush to get back to their own time before they cease to exist. Meanwhile, Dregg unleashes his invasion fleet on the city.

An amoeba-like mobster known as GlobFather takes the protein computer, with plans to use it to hack into Earth's military computers and telecommunications systems.
