Warchimedes

Janera's scientific and strategic advisor, and Dungele's older brother. He coordinates the building and selection of the Magma Beasts that are sent to fight Combattler V. After the death of Dungele, he pilots a Magma Beast into battle, attacking Combattler V and giving Janera the opportunity to destroy the Nanbara Connection. When he is defeated, his brain is transferred into a robot body, which he then self-destructs to kill Janera. His name, pronounced "Warukimedesu" in Japanese, rather than being partly based on the English word "war," may be better regarded as a portmanteau formed from "waru" (meaning "evil") and "Arukimedesu" (Archimedes), thus epitomising the classic sci-fi concept of a great but evil scientist.
