Andro Melos

Formed by the Space Devil (宇宙の悪魔 Uchū no Akuma) siblings Juda, Mold and Gina, their main goal was to conquer the galaxy. The army based themselves on Planet Gua, which they get their name from. Eventually, the group went defunct after the Andro Warriors defeated their leader and combatants.

Ultraman X

Followed by Juda Spectre's failed attempt after Yapool revived him, his siblings, Mold and Gina followed his path of being revived as Spectres, contemplating to reform the Gua Army to avenge Juda's death. The army has been reformed and Gina went to the Ultra Flare Timeline to investigate the world and experiments the Dark Thunder Energy while Mold tried to attack Ultraman Victory, the man whom responsible for Juda's death. Reuniting with Gina in the World Where The Ultra Flare Occurred, he brought Sho, Victory's host as their captive but he escaped with Arisa Sugita, whom accidentally kidnapped alongside Victory as they called for Xio's help.

Mold and Gina then planned to harvest the Dark Thunder Energy on themselves and the Gua Army combatants. Summoning the other Gua Army via a space distortion, they fought the Army's resistances, UPG, Xio and Ultramen X and Victory. But as Mold were hoping the Gua Army's arrival, it turned out that Ultraman Ginga had wiped out the entire army and used the distortion as a gateway to join his comrades.

As more members were killed, Mold combined with his siblings into Gua Spectre and tried to use the Spark Dolls in Xio's custody until it was halted by the Ultraman. After Gua Spectre's destruction, the army was disbanded once more. The Shining Sky, and the Land Beneath It
