President Azass holds high command within the Derinja (alternatively Derringer or Gerinya) military, spearheading the initial Earth invasion from an orbital base under the dominion of Grand Deram, the energy-based ruler of their homeworld. He directs planetary assaults using specialized Mecha-Fighters, deploying them as the primary antagonistic force confronting the protagonists in the series' early stages. His tactical command defines this phase of the conflict.

His tenure concludes in Episode 29. Following strategic reassessments by Derinja leadership, Azass is formally replaced by the new commander, Bios. This transition occurs as Albegas destroys Azass's Mecha-Fighter in combat, resulting in his death, which directly paves the way for Bios to assume control of the invasion. Azass's portrayal remains exclusively defined by this military commander role within the primary television series, with no further elaboration in documented supplementary media.
