ThunderCats (1985)

S1E43 The Rock Giant

Mumm-Ra brings forth the Rock Giant, a colossal creature of stone that looms over the TCats like a mountain. Once it awakens, Mumm-Ra commands it to obliterate Cats Lair. The TCats make an attempt to vanquish the giant using the Thundertank, but ultimately, they succeed in defeating the beast with the aid of the Sword.
