Desperate for a comeback, Titanium Rex books an appearance for the team at a comic convention. In one of several humiliating experiences, he bumps into an old '90s version of The League, obsessed with pogs, roller blades and earning Rex's approval. Meanwhile, Lex is lured on a date.
The League of Freedom is a superhero group that is led by the aging superhero Titanium Rex. From their base called SuperMansion in the fictional city of Storm City, Titanium Rex and his fellow superheroes Black Saturn, American Ranger, Jewbot/Robobot, Cooch, and Brad struggle to keep the team relevant when occasionally visited by the government accountant Sgt. Agony even if it involves fighting an assortment of supervillains like Dr. Devizo as well as Titanium Rex's daughter Lex Lightning.
