Megahertz (メガヘルツ,   Megaherutsu?) is a kaiju created by Toho that first appeared in episode 7 of the 1972 tokusatsu kaiju series, Assault! Human titled The Blast Phantom Megahertz Television Station!!.


Megahertz resembles a large moth with strange, ear-like wings. His skin is mostly black, with white ridges running over it which appear to correspond to the positions of certain bones underneath, such as his ribcage and femurs. On his upper legs, Megahertz has a series of red bumps, which may be armor plating or a defense system.
