The Thundercats go on the offensive taking down Mumm-Ra's lizard army piece by piece. Lion-O appeals to the soldiers to turn against their overlord, but Mumm-Ra won't see his army crushed so easily. He tasks Slithe with recruiting two new and vicious Generals - Addicus and Kaynar - to retaliate against the cats. Meanwhile, the Robear Berbils make Panthro a new set of robotic arms and soop up the Thundertank.
