Cobra helicopter is a personal aircraft piloted by Foot Soldiers in Teenage Mutant Ninja Turtles III: The Manhattan Project. Despite their name, they are not actually helicopters, as they lack propellers.
Two of the Cobras show up at the end of the first half of the second stage, acting as sort of a mini-boss. They hover above the players and fire from a front-mounted machine gun, and occasionally attempt to ram the Turtles as they fire. Unlike their very similar predecessors the Blackhawks, they lack a secondary weapon. After destroying the Cobras, the Turtles head to Baron Von Spleen's Battle Barge for the second half of the stage.
Two Cobras also appear in Krang's spaceship.
Cobras make their return in Teenage Mutant Ninja Turtles: Shredder's Revenge.
