- "Shadow Moon is strong, he will become a king after defeating Crisis. He has promised me to be ranked as a General. That's why I'm not scared with you guys."
- ―A brainwashed Matbot confronting the Crisis Officers.[src]
A white-haired anteater monster with crab claws for hands. The Crisis Empire used it to dig into a mountain to cause a volcanic eruption until Shadow Moon took control of it. When he encountered Shadow Moon, he was brainwashed by his spell to follow his orders. As soon as Kamen Rider Black RX encountered Matbot, he attacked the other Crisis Empire officers who fought back due to Shadow Moon's brainwashing and he proves to them that Shadow Moon is stronger than Crisis. RX escaped the cave-in and ended up engaging Shadow Moon in battle. Gedorian disciplined Matbot at their base and General Jark told Gedorian to use Matbot to capture two children for revenge on Shadow Moon. After defeating Shadow Moon, RX became Roborider and fought Matbot underground, who then went above ground while Roborider disarmed some bombs. Acrobatter tackled Matbot and Roborider used his Vortech Shooter to blast off his right arm. Roborider then reverted to Kamen Rider Black RX and destroyed Matbot with the Revolcane.
