Gamor acts as second-in-command to Colonel Eldomain in the Afressian military, displaying consistent overconfidence and dishonorable conduct. He targets the young Hiroshi Umino, assaulting him twice and repeatedly attempting to kill the unarmed boy—including drawing a weapon during confrontations.

In the Afressian-orchestrated Daibaran hostage crisis, Gamor participates in capturing civilians to lure Emeraldas. When hostages escape, he pursues their vessel and fires upon it, critically injuring Hiroshi’s employer. His antagonism culminates in a final confrontation where, enraged by Emeraldas’ victory over Queen Baraluda, he fires indiscriminately in a crowded control room. This reckless action accidentally wounds the Afressian mechanoid Ruda before Hiroshi retrieves a weapon and kills Gamor.
