Emperor Dazan emerges as the central antagonist who annihilated planet Apolon and executed its ruler, King Takeshi, father of the series’ protagonist. Commanding the formidable Dazaan Army, he launches a ruthless campaign to dominate Earth, deploying mechanical beasts and advanced forces to eradicate opposition. His brutal invasion of Apolon aimed to plunder the planet’s resources, chiefly the Energy Heart—a potent power source intrinsically linked to Apolon’s royal bloodline.

Through relentless assaults orchestrated by loyal subordinates and monstrous biomechanical entities, Dazan strives to obliterate Takeshi and the defenders piloting the guardian robot Dai Apolon. His military might combines cybernetically augmented soldiers, covert assassins, and hybrid creatures engineered for devastation. The conflict culminates in a final confrontation on Dazan’s homeworld, where Takeshi challenges the emperor directly in a decisive clash.

Dazan’s origins and personal motivations remain shrouded, his character defined singularly by his hunger for conquest and tyrannical rule. Unwavering in his antagonism, he undergoes no redemption, embodying pure despotism. His eventual defeat dismantles the Dazaan Empire’s grip, liberating both Apolon and Earth from his oppressive reign. The character’s presence is exclusively confined to the main series narrative.
