Regiwani

Regiwani is the leader of all the summoned crocodiles. He is a massive, alligator-like creature, and amphibious. While, unlike other large summons of the crocodiles, he does not have specialized techniques, he has a huge amount of brute strength, to the point where he could likely pick up Gamabunta without much trouble. He also has the ability to let loose great amounts of earth and molten rock, devastating his enemies, and is impervious to most attacks.

He has been summoned only once in the series, and it is said by Rutiwani that he does not like it at all. However, when shown what he considers a good reason for his summoning, he fights loyally for whoever summoned him. Utakata summoned him when Shinpite was overpowering both him and Odayaka. His abilities managed to nearly defeat Shinpite, but Utakata was captured in the end.
