Sazer-Gans

Tappei Mikami (三上 辰平  Mikami Tappei? ) is a kind guy who studies and takes care of some  dolphins at an ocean theme park. He likes dolphins a lot. He likes to go surfing. He underwent training with Ryoko until he was fully awakened. The opportunity finally came, and he joined his tribe members, completing the Water Tribe. Tappei is gentle and open-minded, ready when he is needed.

With his Knuckle Riser, Tappei transforms into Sazer-Gans (セイザーギャンズ Seizā Gyanzu? ), the water warrior under the sign of Cancer, with armour shaped after a manta ray in sky blue. Sazer-Gans' main weapon is the Kallinikos (Greek; Great Victor), a double blade halberd. Its finishing attack is called "Taikai Shousetsudan", which shoots a stream of water.
