The Great Leader of Destron is the leader of the criminal organization Destron and the second incarnation of the original Great Leader. He remained hidden for most of the series before being revealed to be a living skeleton with a beating heart, calling himself the God of Death. He is the main antagonist of Kamen Rider V3.
He initially led directly, ut later he let one of his generals lead for him. His monsters are typically a combination of a manmade object and an animal.
In the last few episodes, he appeared in person for brief periods of time, but he wore a robe with a hood which hid all of his features. In the final episode, he confronts and fights Kamen Rider V3. V3 cracks his skull open, revealing a tape player with a recorded message from the Great Leader, hinting that the skeleton encountered was just a decoy for the real Great Leader.
