After re-energizing the present-day Turtles, the Turtles of the past have only 3 hours to get back to their time, or they will all cease to exist. Meanwhile, during the 15 hours it took to re-energize the Turtles, the remainder of Dregg's invasion fleet has been completed and has been unleashed on the city and now the Turtles and Carter have to stop Dregg, Krang, and Shredder.
Lord Dregg teleports Shredder and Krang from Dimension X to the Dreadnaught in order to learn more about the Turtles and Earth's weapons. Meanwhile, after permanently stabilizing his mutation, Carter finally leaves the Turtles and returns to college.
After draining the Turtles' life energy & Krang's intelligence, Dregg plans to fire the Vortex Transporter at the Sun, bringing a piece of the Sun down to Earth. If the people of Earth refuse to surrender, Dregg will cause the Earth to become a second Sun. Meanwhile after learning of the situation, Carter returns, and knowing he can't handle it alone, Carter contacts the turtles' friends Landor and Merrick who brings the turtles' past selves to the present as well as Splinter mentioning to him that despite his mutation being stabilized, there is a chance that Carter can still mutate.
