Subtitle: Amphibian Type Beast (アンフィビアタイプビースト Anfibia Taipuu Bīsuto?)
Frogos and Arakunia were Space Beasts sent by Dark Mephisto as subjects to test the Night Raiders in action, specifically Mizorogi (who had joined the Night Raiders). Frogos was spotted in a Parking Facility where it attacked the Night Raiders with its fireballs. However, the monster was no match for the Night Raiders' weapons and was quickly killed by their gunfire.
- Frogos was made by combining the head of the Bokurag costume (from Ultraman Gaia) and the body of the Tablis costume (from Ultraman Cosmos.)
- Frogos's suit would later be used to create the monster Kaiprose.
Ultra Galaxy Mega Monster BattleFrogos briefly reappeared in episode 7 of the series, Ultra Galaxy Mega Monster Battle.
- In this series due to the more staggering sizes of the other monsters, Frogos's size is boosted to 40 meters rather than his original 10 meters. As a result of his size boost, this incarnation of Frogos is known as "Frogos (B)" which means Frogos (Big).
