Super Fénix begins as an infant entrusted to Rojin Hood by Super Zeus, who departs to confront Super Devil. Hood raises him until Mashou Nero murders Hood, triggering the infant’s first transformation via Cyber Up to obliterate Nero. This act sparks his vengeful crusade against demonic forces.

His mission centers on halting the demon king’s resurrection by hunting eight fragments of an ancient litograph. He allies with humans wielding divine powers, journeying across terrestrial, angelic, and demonic realms. During clashes, he achieves powered-up evolutions like Head Rokoko.

Later, he emerges as a legendary hero’s heir, his powers awakening amid invasions that drive him to lead assaults against demonic entities menacing multiple dimensions. His arc fulfills a destiny of cosmic warfare and protection, with relentless battles forging his role as a pivotal warrior in the angel-demon conflict.
