Earth (1987 TV series)

Earth, in the 2017 Nickelodeon crossover also refered to as Earth 7, is the 1987– 1996 animated series representation of Earth.

In the first 5 episodes, Shredder tried to conquer Earth with his army of Foot Soldiers and his mobile fortress the Technodrome. In the last of the five episodes the Turtles trap the Technodrome in Dimension X, along with Shredder, Krang, the Foot Clan and Bebop and Rocksteady inside. Since then Shredder, with Krang's help, tried in many episodes to get his Foot Soldiers and the Technodrome out of Dimension X to finally conquer Earth, but the Turtles always foils their plans. In many episodes, Shredder tried to conquer Earth by other ways, but these plans are also foiled by the Turtles.

In the episode The Fifth Turtle, the Earth is one of the celestial bodies in the conjunction where Krang uses Capsidium crystals to re-power the Technodrome.

During the last two seasons, when Shredder and Krang were trapped in Dimension X for good, extraterrestrial warlord Lord Dregg tried to conquer Earth by manipulating the people, letting them believe that he is an hero who came to save them. The Turtles unmasked him and trapped him in Dimension X.

However, Shredder, Krang and Dregg were not the only ones, many villains tried to conquer Earth or parts of it, but luckily the Turtles always stops them at the end.
