Megalon

Megalon is a fictional giant insectoid monster that first appeared in the 1973 Toho film of the same name. The creature is known for its drill-like horn on its head, large beetle-like wings, and powerful claws. Megalon is depicted as an inhabitant of the underwater kingdom of Seatopia, a civilization that emerges from the ocean depths to seek revenge on humanity for atomic testing that has disrupted their environment.

In its debut film, Megalon is allied with the alien Gigan, and together they battle Godzilla and Jet Jaguar. Megalon possesses the ability to fly and can also fire a destructive beam of energy from its horn, which it can also use as a battering ram. Its physical strength is considerable, allowing it to engage in close-quarters combat with other kaiju. Megalon's design is distinct, characterized by its robust exoskeleton and powerful, articulated limbs. It has since made appearances in other Toho productions and has become a recognizable figure within the Godzilla franchise.
