Driven by their relentless desire to vanquish the Thundercats, the Mutants once more scavenged components from their crashed spaceship. They repurposed the vessel’s engine, transforming it into a formidable device capable of launching colossal fireballs. With this devastating power, the Mutants subjected Third Earth to a reign of fiery terror, until the Thundercats journeyed to Castle Plunn-Darr and obliterated their perilous new weapon.
