On the cybernetically advanced planet of Cyborgia, the Cyberones thrived under the divine guidance of their creator, the Beast God. As his era drew to a close, the Beast God foretold the birth of three siblings from his lineage who would carry his legacy and protect Cyborgia in the future. A millennium later, this prophecy came to pass when Queen Miyako, wife of King Horizaki, gave birth to Max, Yukazo, and Romaya within the grand halls of their palace. But the joy of their birth was overshadowed by the threat of Zex, a powerful and malevolent villain who sought to annihilate Cyborgia. With Zex's destructive force looming and the planet's fate hanging by a thread, King Horizaki made the heart-wrenching decision to send his children to Earth, ensuring their survival and the continuation of the Beast God's legacy. As Cyborgia was obliterated in a mere five minutes, the three siblings found themselves alone on Earth, unaware of their true heritage or the dark force that destroyed their home. Now, they must uncover their origins, harness their latent powers, and prepare for the inevitable clash with Zex, all while adapting to a new world that is unaware of the cosmic battle that lies ahead. Legacy of the Beast God is a gripping tale of destiny, survival, and the enduring power of a divine lineage, as three siblings embark on a journey to fulfill their prophesied roles and avenge their lost world.
