The Undetectable Air Raider of the TMNT Fleet! Donatello can't help but tinker, even if it means with dangerous technology! Meet the Mutant Copter, the latest in high-flyin', Turtle-ridin' action! Built from the remains of the Nanobot Monster, this triple-rotor-blade high-rider is custom-crafted to cloak and attack behind enemy lines. From its self-repairing armor skin (the source of the nano-technology) to its vacuum propulsion system, this is one cool copter: no radar on Earth can detect its presence, no missile can take it down!
