The Lair  is the home and base of operations for the Teenage Mutant Ninja Turtles in the Turtles' dimension.
Donatello, Leonardo, Michelangelo, Raphael, Casey Jones, and April O'Neil tested the Interspatial Teleportation Unit in Harold's Laboratory by setting the coordinates to the Lair. Due to Harold Lillja's attempt to kill an annoying fly, a switch was accidentally hit. The Turtles, April, and Casey appeared in the Lair briefly. By the time Splinter turned around, they were gone and he assumed the television was left on again. The Turtles, Casey, and April were teleported back to their home dimension and arrived in the Lair. Splinter mistook their return as them finally mastering their stealth skills.
Winston Zeddemore and Leonardo crossed over into a parallel version of the Turtles' Lair. Leonardo thought it felt familiar, but the use of the Remote Portal Access Band attracted a ghost. Rather than lug Traps around, Winston simply atomized it with his Proton Pistol then they jumped to the next dimension.
- On page 2 of Teenage Mutant Ninja Turtles/Ghostbusters Volume 2 Issue #2, Winston and Leonardo teleport into the Turtle Lair from the Teenage Mutant Ninja Turtles 1987 animated series. Leonardo's look is based on that series' design.
