Rise of the Stay Abyss Overlord

Betrayed by his brother Zane who steals the prized SSS-class mecha core to chase hero glory, Xavier Grant is exiled in disgrace. He defiantly selects the mocked F-class mecha, finding sanctuary in the Wasteland with three fellow outcasts. Together, they unlock the underestimated mecha's true potential, forging an unstoppable team from the ashes of rejection. As a catastrophic threat unleashed by the stolen core ravages the Capitol, Zane's ambition crumbles and the family that scorned Xavier faces ruin. From the deepest abyss, the true overlord rises to save the very world that cast him out.
