Mechaturtle (also erroneously spelled as Mecaturtle in the manual and Mekaturtle in Nintendo Power) is the third boss of the first Teenage Mutant Ninja Turtles console/PC game. It is fought on a rooftop, where Master Splinter is being held captive. The Mechaturtle's initial appearance is that of a blue-green, purple, or blue skinned Teenage Mutant Ninja Turtle with a tan or green headband and joint pads. It wields a sword similar to Leonardo's, although it does not do actual damage, presumably due to incomplete programming. Upon this form's defeat, it reveals its true appearance; a vaguely turtle-esque automaton that fights with a blade, gun, and missiles. Destroying this form defeats it once and for all, and effectively, Splinter is freed.
Behind the scenes
Mechaturtle's flesh is blue and his headband and joint pads are green, in the PC version.
Mechaturtle's flesh is purple and his headband and joint pads are green, in the Amiga version.
In the Atari ST version he starts out in his robot form.
His first form is often confused for Slash, while his second is confused for Metalhead
Although unconfirmed, it is possible that the "Fake Brother" seen as a mirror match in the SNES version of Tournament Fighters (which has a different palette from the Turtles' 1P and 2P colors) may actually be Mechaturtle.
