In a secluded wasteland on the world of Zi, a youth named Van stumbles upon a derelict complex. Within the ruins, he discovers a translucent shell that ruptures spontaneously, revealing a dinosaur‑shaped automaton dubbed an "Organoid." Van christens the machine Zeke, claiming it as his own, yet a gang of marauders soon pursue him to capture the Organoid. The raiders wield "Zoids," beast‑like mecha used for battle. Van counters the assault by reanimating and merging with a relic Zoid known as the "Shield Liger." Returning to the site with Zeke in tow, Van spots a fresh cocoon. He is thrilled at the prospect of another Organoid, but when the shell cracks, a girl materializes instead. The newcomer remembers only her name, Fiona, and the mission to locate an artifact called "Zoid Eve." Determined to unravel her origins, Fiona joins Van and Zeke on a quest to uncover the true nature of the Zoid Eve. Together, they encounter allies and adversaries alike, face perilous trials, and share moments of levity along the journey. Their odyssey weaves through ruins, landscapes, and whispers of ancient tech hinting at deeper purpose. They forge an unbreakable bond guiding them toward Zi's secrets.
