The ShodaiEbira's name comes from shodai (初代?), meaning first generation, and Ebira, which comes from Ebirah's Japanese name, Ebira (エビラ?).
The ShodaiEbira suit is a fairly simple one. The suit is fat and unsegmented, its left claw is more massive than the right one, it has crustacean whiskers, eyes on stalks, and about six legs. It also has big eyebrows and spikes on its back, as well as fairly long scythe-like pointy crest, and seems to have a mouth like Mothra's, one that is flipped on its side.
