ThunderCats Roar (2020)

S1E23 Ratar-O

The ThunderCats have become so adept at taking down the Mutants of Plun-Darr that it feels like a regular occurrence. However, everything shifts with the return of the Mutants' former leader, Ratar-O, who possesses the powerful Sword of Plun-Darr. This spells trouble for our heroes.
