The Technodrome

The Technodrome is the second lair of the Masters of Evil. It debuted in Pooh's Adventures of TMNT: Turtles Forever under the ownership of the 1987 Shredder and Krang. They brought back the Utrom Shredder for the frozen asteroid and thawed him out. After the final battle at Turtle Prime, Bowser sent the 1987 Shredder, 1987 Krang, and 1987 Bebop and Rocksteady to Dimension X so they can get a new Technodrome, while he gets this one.
