Lex.Lex Lightning comes to the mansion and reveals herself as Rex's daughter. Rex tries to bond with her but panics and abandons her at a mountain. Sgt. Agony tries to use this as an excuse to shut down the League of Freedom because Rex is a bad father, so Rex pretends to be good to Lex to improve his reputation. Lex discovers Rex's ruse after their battle with Robo-Dino, who only agreed to a fight if Rex sells him the rights to his name. Lex leaves, but is kidnapped by Robo-Dino to get revenge. Rex and Lex fix their relationship and stop him. The male members instantly develop a crush on Lex, and after finding out she likes bands they form a band called Razordick. Despite their lack of talent, they end up signing a contract with Jewbot's rabbi, and they can't get out unless they find a song that their manager likes. They do release a single, but the song is a critical and commercial failure, while the song their manager refused to allow them to record turns out to be a big hit...for the manager and his new group.
