Synopsis

Mumm-Ra roused the Rock Giant from its slumber—an age-old beast of stone that appeared to the ThunderCats as a towering mountain. Upon awakening, Mumm-Ra directed the colossal being towards Cats' Lair, intending its destruction. The ThunderCats attempted to repel the giant with the Thundertank, and ultimately, through the power of the Sword, managed to bring it down.
