Forx loves destruction, but he is very clumsy. The Weldos are known for building and repairing, but Forx sometimes lets his enthusiasm for destruction get the better of him. Forx aims at the bad but sometimes hits the good, too, only allowing his onlookers to check the damage after he rolls to a stop.
Forx and his tribe made their debut in The Quest For The Lost Mixamajig. After King Nixel was defeated and his core was ripped out, Forx and the other Weldos appeared. Forx assisted in building Mixopolis and may have survived the Nixel Invasion afterward.
