ThunderCats (1985)

S2E11 Catfight

Mumm-Ra activates the Beacon of Ravage Island, turning the Thundercats into his obedient servants. Under the beacon's influence, Lion-O, Panthro, Cheetara, and Pumyra are swiftly seized by the Mutants. Snarf races to the tower to gather the remaining allies for assistance, but soon, Ben-Gali succumbs to the beacon's control as well. It falls to Lynx-O, Snarf, and Snarfer to rescue their fellow Thundercats from this enslavement.
