|This article is about a/an kaijin in Kamen Rider Black RX.|
A slithering blob-like monster with tentacles for arms, able to spray his slime on them with the slime morphing into a clone. Dogmalogma uses his power to create clones of Shigeru, his friends and Reiko as part of Maribaron's plan to use Kohtaro's trust against him. But once he becomes RX, his Kingstone causes the clones to dissolve before he battles Dogmalogma. When the monster attempts to engulf his hostages, RX stops Dogmalogma and kills him with the Revolcane.
