The two-stage boss found at the rooftop conclusion of Level 3 in Konami's (published under the Ultra label) original 1989 Teenage Mutant Ninja Turtles Nintendo Entertainment System (NES) video game (it was also released on various computer platforms, and, more recently, as downloadable content on the Nintendo Wii Virtual Console). Both the turtle and robot forms must be defeated, one after another, to save the TMNT's ratnapped master, Splinter, and proceed onwards to Level 4.

In reptile form, Mecaturtle runs and leaps about with great agility, slashing away at its foes with a razor-sharp ninjato sword. Should an adversary prove capable of besting the villain at this stage, Mecaturtle will change into its true shape, that of a deadly combat droid. This form is considerably more dangerous than the pseudo-terrapin and sports numerous attack capabilities: Jet thrusters in Mecaturtle's feet and back allow the mechanical menace to rocket through the air with ease. While airborne, it can lift its head, in a lid-like fashion, to launch homing missiles out of its torso. The robot's forearms can also reconfigure themselves, on the fly, to become either twin cannons or titanium blades.
