While American Ranger helps Cooch get over the League's recent loss of a member, Titanium Rex and Jewbot must stop a mysterious internet cult from leaking sensitive League information.

Titanium Rex tries to restore The League of Freedom's tarnished public image by traveling to Champston University in the hopes of wooing an old, beloved friend to join the League. While visiting the college, Black Saturn shows Jewbot the ins and outs of fraternity life, and the other members of The League have their own college experience.

The league's newest member, Portia Jones, unveils her first plan for restoring the public opinion of the superheroes: a League of Freedom-themed pizza restaurant and arcade. Rex and the League try to make the best of the embarrassing new venture, and Jewbot has an existential crisis after learning about his disappointing origins.

J.K. Simmons visits the SuperMansion to shadow Titanium Rex in the hopes of portraying him in a League of Freedom movie. Meanwhile, the villains in Storm City regroup to form the all-new Injustice Club, but things get uncomfortable when they move in to a new lair and start to question their leadership.

A Black Saturn from 30 years in the future comes to present time Storm City to stop an event that will trigger a global apocalypse: Zenith and American Ranger having sex. While the older Black Saturn helps The League stop Zenith's goddess mating ritual, present-day Black Saturn is sent to the hellish and dangerous landscape of the future.

A giant alien lifeform, Asteros, comes to earth looking for his Herald, Blazar, but when he finds out that Black Saturn devolved Blazar into a baby monkey, he vows to destroy the earth. With the help of NASA, The League of Freedom must travel into space to save the world from Asteros's violent planet destroying machine.

Black Saturn has gone solo after leaving the League of Freedom and his first case to crack is a string of kidnappings: all women who used to model for famed 70s fashion photographer Mel Gurman. While Saturn tries to track down Gurman, Titanium Rex's old secret identity comes back to haunt him.

After years of searching, Rex's older brother, Titanium Dax, becomes the second Subtopian ever to find his way to the earth's surface. He and his rock monster slave, Liplor, are thrilled to find that Rex is alive and well, but their reunion is soured when Dax threatens to reveal a dangerous secret about Rex's origins.

To protect The League of Freedom, Titanium Rex has gone into hiding, working as a lumberjack far from civilization. While Rex tries to cope with his new identity as a regular, powerless man, Robobot attempts to get a downtrodden League of Freedom back together to take on a massive threat that he's uncovered.

The Subtopian army has come to the earth's surface, and their enslavement of the human race has begun. The League of Freedom must join forces with the villains of The Injustice Club in order to stand a chance against the Subtopian invasion, but Rex, Lex, and Dr. Devizo cannot set aside their differences.
