Frogos (フログロス Furogurosu) is a frog-like Space Beast in Ultraman Nexus.

Subtitle: Amphibian Type Beast (アンフィビアタイプビースト Anfibia Taipuu Bīsuto)


Ultraman Nexus

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, as seen in Ultra Galaxy

Frogos briefly reappeared in episode 7 of the series, Ultra Galaxy Mega Monster Battle.

Frogos was the first monster revived by Bullton to attack the ZAP SPACY. However, Rei summoned Litra to protect the crew and Frogos was quickly destroyed by Litra's fireballs.


  • 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).

Mega Monster Battle: Ultra Galaxy Legends The Movie

Frogos (B) reappeared in the movie Mega Monster Battle: Ultra Galaxy Legends The Movie as one of Ultraman Belial's 100 Monster Army. He was first seen in a shot of the Monster Graveyard as a spirit along with Fire Golza, Hoe, King Pandon, and Zoa Muruchi. He then teamed up Mukadender, Lunaticks, Roberuga II, Alien Valky, Jasyuline, Angross, Gromite, Cherubim, and Birdon to take down Ultraman Mebius. He was killed by Ultraman Mebius's Mebium Blade during the final battle.


  • Two Frogos and two Angross appear in Belial's army.
  • It is unknown whether or not that Frogos is part of Beryudora. The same goes for Banpira and Alien Reflect.
