Return to Thundera Part II

Snarfer's radio picks up strange signals from the direction of the Churning Rocks, and Mumm-Ra answers them by raising Grune the Destroyer out of his tomb. Grune's mace encases Cheetara where she stands, and without the Sword of Omens, as Lion-O says plainly, the ThunderCats are nothing. A filthy black cloud on the horizon turns out to be the Flying Furnace and its owner Charr, who has ideas of her own about who the prisoners belong to.
