Fly Mutant

The Fly Mutant appeared in 1988 TV series called Kamen Rider Black. The Fly Mutant (ハエ怪人 Hae Kaijin) is a fly Gorgom monster.

The Fly Mutant was sent alongside Grand Mutant Baraom to find a psychic who can find the dead spirits in a plot to revive some of the defeated Gorgom Mutants to cause havoc in the city. They find one in a boy named Yuki and they trick him into assisting them. Fly Mutant then merges with Yuki's energies to revive them as Phantom Mutants which causes a strain on Yuki's brother Mokoto. During his fight with the spirits of Silkworm Mutant, Rhinoceros Mutant and Longhorn Beetle Mutant, Kamen Rider Black discovered that Yuki was possessed by Fly Mutant. Yuki got away with the three Phantom Mutants. With help from Mokoto, Kohtaro found Yuki at a railroad station as Fly Mutant uses him to have the Phantom Mutants attack. After Mokoto drives Fly Mutant out of Yuki's body causing the Phantom Mutants to disappear, both of them collapse from the psychic strain they went through. Kohtaro transforms into Kamen Rider Black and fights Fly Mutant. Upon being hit by the acidic substance, Kamen Rider Black summoned Road Sector who tackled Fly Mutant and then used its spray to send the Fly Mutant's own substance back onto himself. Kamen Rider Black then killed Fly Mutant with the Rider Kick.
