Sgt. Agony, assigned to report on League spending to Congress, is shocked by the league's wasteful expenditures, and his report results in the League's defunding.

Black Saturn stops his arch-nemesis Groaner and while in jail, Saturn is shocked to find that Groaner has been ejected from the Injustice Club, as Groaner was his only nemesis to have earned membership, but is even more shocked that Groaner hates the other League of Freedom members more than him, and doesn't consider Saturn an arch-nemesis.

Rex scolds Saturn as he has spent the most money, though it turns out Groaner had stolen Saturn's credit card for his own purposes. Saturn is happy that their rivalry played a role in the situation, Finally Brad suggests simply falsifying the records to regain funding, although Sgt. Agony convinces Congress to cut the budget, promising to end the League of Freedom.

Notes: Basically an extended version of the Übermansion pilot with all the footage reused along with new filmed footage.

Rex is saddened to learn that his ally Omega Ted died. After learning Ted was murdered, he suspects an enemy from their past: Frau Mantis. Rex and American Ranger go to Omega Ted's H.Q in Antarctica. After realizing he hasn't spoken to Ted in over 40 years, Rex admits he has been a bad friend and Ranger gets angry at Rex as he thinks Rex didn't try enough to find him when he was stuck in the Time Tunnel, instead delegating the effort to Omega Ted.

Meanwhile according to Omega Ted's will, the League gets custody of his Omega Pets consisting of Buster Nut the Squirrel, Chet the Bulldog, and Ganky the Pony. At first, the League is overjoyed at the news. However, the relationship takes a turn for the worse as Ganky abuses Brad, Buster Nut controls Cooch, and Chet annoys Jewbot. Black Saturn gets jealous that he doesn't have a super pet so he get his own pet called Murder Pig.

Rex and Ranger discover that the Omega Pets killed Ted and inform the League. The pets reveal they want revenge on the League for keeping them in Antarctica because Rex made Omega Ted go there to find American Ranger. The Omega Pets were defeated by the League and the Murder Pig where Ganky was killed by Brad.

While waiting for his medicine prescription, Rex flashes back to when he left Subtopia and arrived on the surface of Earth. Rex throws out his back while fighting the intergalactic villain Blazar. A clip of the abortive battle goes viral and leads to speculation that Rex is too old to lead the League. Jewbot tries to help Rex craft a younger image. Rex decides to debut his younger look and attitude on a talk show, but things go south when he insults Blazar and accidentally puts the host in a coma.

American Ranger constantly brings up the subject of whether Rex should retire after the incident, but other members keep changing the subject, with Black Saturn particularly obsessed with who ate his burrito but eventually the League decides to have a secret election and place the ballots in a folder. After finding the folder, Rex decides to return to his home of Subtopia and never come back. Blazar finds out Rex insulted him on television and attacks the League.

Rex opens the folder and finds out no one wants him to leave, so he comes back and stops Blazar by pretending to surrender but then detonating a bomb he had installed on Blazar's space bike and then beating him up with a pipe. That incident also goes viral and makes people forget about the previous battle.

Rex finds out Ranger's sidekick Kid Victory has become Secretary of Defense, so Rex suggests that Ranger invite him to dinner to convince him to raise their budget. Things go horribly wrong as the league is late with the groceries, and American Ranger is appalled to learn Kid Victory is gay and ends their friendship. He starts to send an advertisement for a new sidekick online. American Ranger apologizes and he and Victory renew their friendship.

While grocery shopping, Black Saturn finds an old enemy, Bugula. however, Bugula has reformed and gotten custody of his child back on the condition that he constantly wears a leg collar that detects blood alcohol. Saturn tries to apprehend Bugula, putting multiple innocent bystanders in danger in the process by accidentally hitting them with blowgun darts full of tranquilizer. Eventually Bugula decides to prevent further injuries to noncombatants by surrendering. Bugula jabs a tranquilizer dart into his own leg, triggering the leg collar since it turns out Saturn's darts contain 40 percent alcohol by volume. Bugula is arrested and loses custody of his child.

Brad's dealer Lucini Mancozo and his partner Tonio shows up at SuperMansion wanting to talk to Brad. Identifying Lucini Mancozo as one of the FBI's most wanted, Kid Victory suspects that the League of Freedom is associated with the Mafia which Titanium Rex stated that the League of Freedom are upstanding law-abiding superheroes. SuperMansion is then raided by the authorities who got a tip that someone on SuperMansion grounds was trolling young boys which American Ranger admits to as the FBI finds the dummy. When Black Saturn, Brad, Cooch, and Jewbot return, they find that dinner was made because Lucini's cousin Angelo makes the best gabagool while Kid Victory has cleared things up with the FBI. As Rex vows not to send the four of them shopping again, Cooch reveals that they are banned from the grocery store. Lucini and Tonio are later taken away by the authorities. Kid Victory agrees to improve the budget, but reveals to Rex secretly that the deal is contingent on Rex ending his affair with American Ranger's wife Gloria.

A School PSA reveals Cooch is illiterate and Sgt. Agony tells the League of Freedom she needs at least a high school diploma or higher to stay in the League of Freedom. The League of Freedom helps her prepare for her GED test, but Cooch has trouble studying. Jewbot discovers Cooch has ADD and suggests Adderall, so she obtains some from Brad and is doing well until the day of the test when Jewbot gets rid of the drugs thinking they are birth control pills, she panics and moves back to her owner.

When helping Cooch with history, American Ranger is shocked to find out what happened to America the years during his freezing and goes to Detroit where he is saddened to learn that the America he knew is gone. He gets introduced to marijuana by a man named Reggie and becomes addicted. Through him, American Ranger meets a Native American named Hawkfeather and inadvertently summons a beast who attacks him, driving him back to SuperMansion.

Cooch comes back and takes the test which she passes. Since she didn't sign the test, Sgt. Agony uses this reason to remove Cooch from the League of Freedom. Just then, the beast attacks the mansion and Cooch saves the day. Hawkfeather reveals himself as a professor at New Mexico State University and awards Cooch an honorary degree, allowing her to stay in the League of Freedom.

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.

Because he has no male genitals, Jewbot decides to become a female with help from Cooch and Lex. Jewbot is now Bernice and when they go clubbing the girls get jealous of the attention she attracts. When Cooch reveals that this was exactly the same jealousy she felt when Lex joined the League, the two bond.

After being dumped (and poisoned) by Blood Moon, Black Saturn tries to find a new girlfriend fails miserably. Eventually, he gets desperate enough to ask his old foe and long-term League of Freedom prisoner Groaner for help. After several more failed attempts even with Groaner's prompting, he again runs into Blood Moon who is accompanied by her new boyfriend Carbonaut, a recent graduate of the Muscle Ream Academy (which forms the "B" story of the episode). The encounter is an utter disaster, and Black Saturn gets so drunk he takes home a "girl" after all..."Bernice."

Titanium Rex, Brad, and American Ranger start training at Muscle Ream when they get a coupon, which turns out to be a trap by Johnny Rabdo to defeat the League and become a member of the Injustice Club, but Rabdo is defeated by Black Saturn when Bernice breaks up with him and Black Saturn takes out his anger on Rabdo. Bernice becomes Jewbot again because being a woman is hard and Cooch hates Lex again because she is the new girl once more.

The League of Freedom defeat the plot of Rat-A-Pult and Quiplash. Optocorp stops providing Brad his Super Serum, having found a new recruit named Chad who is taking a new serum that makes him stronger than Brad because of Chad's higher chemical tolerance. Brad, Cooch, Saturn and Groaner break in and steal the remaining serum so Brad gets his strength back.

Rex hosts game night, but turns out to be a sore loser, so the League tries to avoid game night and even replaces themselves with holograms. Eventually Rex decides he has had enough and goes to bed.

Lex becomes sympathetic towards Saturn when Saturn reveals he wants his parents' love and how he hates his younger brother Dudley because his parents love him because, in his words, his parents say his brother wants to become a "real adult." Lex and Saturn start dating.

Rex wants to cancel a cable subscription from CableVerse, but when he calls, an employee named Rajish refuses to accept his request. Rex finds the branch office and discovers all the employees pretend to be Rajish. Rex finds Saturn working there. His father Cliff owns the cable company, so Saturn agrees to cancel it to spite his parents. While his parents are still impressed with his relationship with Black Saturn, he secretly photo-cashes the check before ripping it as he was also able to get rocket shoes for Lex.

Jewbot spends the day with Dudley. Jewbot sees Dudley as a boy who does not get love from his parents and Saturn. However, Jewbot finds out Dudley has a secret life as a drug dealer. They are kidnapped by Russians who also kidnapped Dudley's nanny, but Jewbot saves them with help from Cooch and Brad.

In the final scene, Dudley gets into the tub with his nanny as he rips the head off the Black Saturn action figure.

The League of Freedom goes on vacation in the woods and Lex tells her father to tell the truth to American Ranger about his affair with Gloria. While fishing, Ranger tells Rex how difficult it is to be married to Gloria now that she is an old woman and that he wants to live his life. Rex tells the truth and Ranger is angry that Rex not only had an affair with his wife but continued even after he was found out, so they end their friendship.

Lex wants to have sex with Black Saturn who brought his family butler Bunsen along, but he refuses because he is scared of being caught by Rex and what he may do.

Rex wants the League to be careful of Dr. Devizo who intends to break out of SuperMansion's prison on the anniversary of his incarceration. Dr. Devizo and Rex talk in the cell and Dr. Devizo reveals that he was a member of the League, but became evil after finding out Rex had had an affair with his wife. After realizing Ranger, now in the same situation, could also turn to evil, Rex leaves to find him and Devizo hatches his escape.

Ranger, taking a cue from the movie Hall Pass, seeks to have a one night stand to get revenge on his wife for having the affair with Rex. Ranger finds a girl but when they reach her apartment Rex arrives with Gloria. Rex and Gloria apologize and acknowledges that Ranger is trying hard to maintain his marriage to Gloria and she says she understands if he wants to end it, but they reconcile and Gloria agrees to try. Devizo almost escapes because of the other League members' incompetence, but is finally brought to heel by Lex, whom Rex had earlier forbidden to participate. The event garners headlines for Lex.

Billionaire Ivan Whiff starts his own superhero league and offers Lex the chance to be the first full member. Lex, who feels stifled by her father and stuck interning for the League of Freedom, accepts the offer after considerable thought, but finds out that this was a plan by Agony and Whiff to use Lex's popularity to make Team Whiff popular so they won't need the League of Freedom, so Lex stays with her father. Jewbot becomes a doctor for the League of Freedom despite his unpopular bedside manner. In a twist ending, Jewbot reviews Lex's medical analysis and finds insect DNA on her as Lex beheads Jewbot.

She teams up with Dr. Devizo where she releases him and the villains Blue Menace, Groaner, Buster Nut, Chet, Blazar, Bugula, Robo-Dino, Johnny Rabdo, Rat-A-Pult, and Quiplash from SuperMansion's prison. Lex reveals that her mother is Frau Mantis and wants revenge on Rex for letting her mother die in the fall. Much to the shock of Rex and Saturn, Lex has the ability to change gender thanks to inheriting her mother's mantis DNA; Saturn faints in response. Dr. Devizo plans to launch nuclear missiles with the codes that Lex stole from Ivan Whiff and puts the League in their own prison. They escape and fight the villains where Groaner released Black Saturn since it would be difficult for him to find another worthy superhero for him to fight as Chet is accidentally evolved. Titanium Rex blinds Lex, Black Saturn devolves Blazar to a monkey, American Ranger rescue Gloria from Blue Menace, and the League of Freedom stops Dr. Devizo. Brad sacrifices himself to destroy the mainframe by burrowing into the underground lava to save the world, but the mansion is destroyed in the process and the League mourn for him while the villains get away. Even Sgt. Agony mourns him as he admits Brad was the only League of Freedom member he liked. Three months later, the mansion is getting rebuilt and a statue of Brad is dedicated to him.

The League is still in turmoil after Dr. Devizo destroyed the SuperMansion and released all of the villains into Storm City as the League of Freedom tries to apprehend Groaner and Buster Nut who have been sent out to gather food for their fellow villains. While American Ranger helps Cooch get over the death of Brad, Titanium Rex and Jewbot must stop a mysterious internet cult led by the Third Eye from leaking sensitive League of Freedom information. Meanwhile, Black Saturn looks for a replacement for Groaner which doesn't go well. When Titanium Rex gets onto the Internet with Jewbot's help, he confronts the Third Eye and discovers that it is the virtual reality form of Dr. Devizo who has brought Lex into the virtual reality.

During this time, he comes across his boss Ol' Pappy having problems when a logging mogul named Marcus Rector buys up half the valley. Now Titanium Rex must find a way to help Ol' Pappy against Marcus Rector and his sons Elton Rector and Billy Joel Rector. Meanwhile, the other League of Freedom members haven't been seen by Sgt. Agony for months and Robobot during his work as a data entry worker at the Seismology Institute works to find them upon detecting other Subtopian activities.

Afterwards, the League of Freedom finds the Injustice Club's hideout and persuades them to help against the upcoming Subtopian invasion. When asked for the Anti-Magno Rod that was stolen from SuperMansion, Lex goes to obtain it only to find that Dr. Devizo had swiped it much to her anger.

Rex is welcomed by everyone except her daughter Lex Lightning, who still resents him. Devizo enters and opens the suitcase with the Anti-Magno Rod and declares himself in charge of the truce. Rex reveals that Subtopian technology is powered by Magno, which becomes Anti-Magno upon being depleted of its energy, becoming lethal to Subtopians. Rex and Devizo come up with a plan to invade the Subtopian controlled military base for the atmospheric dispersal device needed to spread the Anti-Magno's energies.

After Dr. Devizo attaches the adapter to the atmospheric dispersal device, Rex flies it high above Storm City. Dr. Devizo arranges for Rex to "die a hero" by detonating the device when he isn't out of range. As the Subtopians retreat, Lex flies into the cloud and catches Rex. Dr. Devizo then carries Titanium Rex's body, taking credit for thwarting the invasion and saving Titanium Rex's life. As a result, Dr. Devizo is pardoned for all of his crimes. Portia gets back together with Ringler and they take their leave much to the dismay of American Ranger and Sgt. Agony and the disappointment of Black Saturn. As Rex is recuperating, he agrees to testify at Lex's eventual criminal trial and offers her a place in the League. Lex states that Lex Lighting "retired" and is now calling herself Titanium Lex. Sgt. Agony then appears on TV stating how villains are misunderstood people and states that he has hired Dr. Devizo to help him oversee the future conduct of the League of Freedom.
