Extroyer has a grey face with white eyes and yellow teeths. Half of his body has his main mode while the other half represents his gorilla mode, which can be mainly noted on his right arm and leg. His gorilla arm is seemingly larger than his normal arm, and his hand is covered with purple crystals. He has 10 points of articulation, and doesn't comes with any accessory.
When his gorilla arm is moved, his face will switch to the face of a mutant gorilla. His gorilla arm also counts with attack action.
- The figure has a very similar appearance to the Mutant Beast Extroyer, which its gimmick consists in turn into a gorilla.
