The ShodaiShisa's name comes from shodai (初代?), meaning first generation, and Shisa, which comes from King Caesar's Japanese name, Kingu Shisa (キングシーサー?).
ShodaiShisa's snout is dinosaur-like, with several teeth visible when it is open. Its eyes are red, (bearing pupils in promotional images) and its ears are bent similar to a dog's. Its upper half is covered in fur and has a kind of gold look to it, and its lower half has fur only on its legs and tail. The suit's skin is brick-like, and its claws are long.
