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.
