“Damn Godzilla. You're mistaken if you think your powers are a match for Mechagodzilla.''

— Kuronuma (Godzilla vs. Mechagodzilla)

The creation of the Black Hole Planet 3 Aliens, Mechagodzilla was the centerpiece in their planned invasion of Earth. The magnificent machine was released from the crater of Mount Fuji wearing a Godzilla disguise, and made its way to Tokyo after dispatching Anguirus. Once it reached Tokyo, the impostor was attacked by the real Godzilla, who quickly revealed its true colors. Mechagodzilla was damaged in the ensuing fight with Godzilla, but was repaired and sent to destroy King Caesar at Okinawa. Godzilla returned and aided King Caesar, and together they were able to destroy Mechagodzilla.
