Teenage Mutant Ninja Turtles apperances
In the 1987 TV series episode Return of the Technodrome, the Ninja Turtles and April O'Neil arrive to the region in an attempt to stop Shredder, Krang, Bebop and Rocksteady from taking over the Niagara Falls hydroelectric power station and open a portal wide enough for the Technodrome to slip through.
Upon arriving, Bebop fires his raygun at the Turtle Blimp, hitting the balloon. The glider crashes into the Niagara River. Using the remote control, the Ninja Turtles and April O'Neil manage to catch the balloon ropes and swing back to land, while the glider unmanned falls into the Niagara Falls.
Later in the same episode, the Nnja Turtles head into the power station and shut down the river's waterflow, temporary closing te portal down. However, Krang uses reserve energy to reopen the portal and bring the Technodrome from the unnamed rocky Dimension X world to Earth.
