Chemies/Malgams

They were stolen away from the Alchemys Union by Fuga, who was forced to release them into the world after entrusting the Chemies' safety to Houtaro. Chemies who end up being exposed to malice-consumed humans are merged with that human to become a single corrupt humanoid monster called a Malgam (マルガム), with Gotchard extracting the Chemy from its host while purifying them. However, a human host with goodwill can merge with a Chemy into a purified version of their Malgam form anytime, even when their eponymous Ride Chemy Card is used by a Kamen Rider. If a Malgam merges with other Chemies, the host evolves their Malgam form into a hybrid Mixtus (ミクスタス) form that transforms the absorbed Chemy into a weapon-like state. With the exception of X Wizard, Zukyumpire, and Nijigon, all Chemies are incapable of human speech.
