|This article is about a/an kaijin in Kamen Rider Black.|
Alongside the Bat Mutant, Gorgom used Silkworm Mutant to capture people and items for its "The End of Mankind" project in Gorgom Studios. It fought Kamen Rider Black alongside High Priestess Bishium. When lured outside, Silkworm Mutant faked its death only to trap Kamen Rider Black in a silk cocoon. Kamen Rider Black got free and killed the Silkworm Mutant with his Rider Kick.
It can bind anyone or anything with the silk threads it shoots from its mouth.
