Nimen Doggler (ニメンドグラー Nimendogurā 36?): A monster sent after twin sisters named Eriko and Mariko, who possess a power that catches Igam's interest. The monster is turned into a pair of masks that are placed on the sisters' faces to keep them apart. Their destructive power is manifested in the form of explosive teleportation. With Ial's pendant, Eriko and Mariko are freed from the masks and they re-form into this monster. After being blasted by the Jet Cannon, this monster was destroyed by Great Five.
