Tepeto was a bio weapon created by the Alien Tepeto. The Tepeto seijin called out to their monster when the Ultra Garrison attacked the base. While Dan Moroboshi was stuck in chains he became Ultraseven! Tepeto and Ultraseven began to fight in the water. During the fight, Tepeto pretended to beg for mercy multiple times, each time causing Ultraseven to let his guard down; Tepeto would then blast him with his water cannon, or trip him and swim away. Before he could get very far, Ultraseven shot the vile alien beast with the Emeruim Beam, then he split Tepeto into two with the Eye Slugger.
- Like the Alien Tepeto, the kaiju Tepeto resembles the kappa of Japanese mythology.
- In the middle-to-late 1990s, footage of Tepeto was used for the TNT, TBS and Cartoon Network show Cartoon Planet. Tepeto footage was used to depict an alien in the recurring sketch entitled 'Messages from Outer Space' that would feature other Ultraseven Kaiju broadcasting to Space Ghost, Zorak and Brak on Cartoon Planet. In his featured message, he was called Gar Jr.; son of Gar and Zelba Fitzgerald of the Sixth Moon of Planet Granth. His friend Zippy (really Ultraseven) is said to be wearing a cheap Ultraseven dress up costume.
- Tepeto has a modified Ebirah roar which would later be reused for Takkong.
- Both Tepeto and its masters were named after the katakana for Peter of the 12 apostles.
