The next morning after confronting Nolan about his murdering the Guardians, Debbie wakes up in her bed and doesn't find Nolan next to her. Debbie goes downstairs and sees the hole Nolan punched in the wall, and finds him looking out on the back yard. His blood splattered Omni-Man costume is on the kitchen counter, and she approaches her.

Will drives back with Amber and Mark, and Amber turns the radio up when Mark tries to talk to her.

At her treehouse, Atom Eve uses her powers to make coffee and refreshes herself from her previous day's exertions. She looks up more disasters on her phone, and goes up on the roof to sip coffee and watch the sunrise.

Debbie asks Nolan why he kept his incriminating costume, and he says that he used it to take care of Damien but part of him might have wanted Debbie to find it. Nolan says that he wanted to tell Debbie the truth months ago, and she asks her husband if he was mind-controlled or blackmailed. Nolan says that didn't happen, and Debbie needs to trust him and if she does, their family will be okay. Debbie says that she can't trust him, and knows almost nothing about Nolan.

Nolan insists that he had no choice but to kill the Guardians, and Debbie says that she doesn't trust Nolan and orders him out of her house. When Nolan says that she doesn't mean, Debbie throws his blood-soaked costume at him and repeats her demand. Nolan throws the costume on the floor, says that they'll talk later, and flies through the ceiling.

Debbie calls Mark and gets his voice mail, and tells him to come home. Donald and GAD soldiers appear in Debbie's living room, and Donald tells Debbie that she has to come with them.

Will drops Amber off at her house, and Mark goes after her. He admits that he's been an asshole, but it all stops that day. Amber starts to say that he's Invincible, and Amber slams the door in his face before he can say it. Amber goes to her room and finds the window open, and finds Invincible hovering there. Invincible removes his mask and reveals that he's Mark, and says that's why he's always late. Amber ignores him at first, and finally says that she knows he's a superhero.

Amber tells Mark that they're fighting because he lied to her, and made her feel stupid and unimportant. She tells him to leave because she wants to be alone, and Mark flies away, leaving the Mars rock on her windowsill.

Monster Girl returns to the Guardians HQ, and the group throw her a surprise welcome back party. Rex has filled milk cartons with beer and hands them out, and Samson jokingly teases Rex. Robot tells Monster Girl that he's delighted at her recovery, and Monster Girl points out that Robot was mostly responsible for her recovery. The mechanical man goes into a loop, then apologizes for a "programming error" and says that it will soon be fixed permanently.

A van pulls up to the Maulers' base and drives in. they shoot at the driver, who doesn't respond. They discover that he's a hologram, and Robot comes out of the back. The creature the Maulers have been creating comes out of the van next, still in its cylinder which is suspended in a robot spider carriage. The Maulers realize that it's the real Robot, and that they've been growing Robot a new body.

Robot has them show him the teenage body they've been cloning. The Robot body analyzes it and says that it's perfect, except for the poisonous sacs the Maulers planted in as well as control synapses. The body says that he'll pay them with a GDA control collar as soon as they remove the secret mechanisms they put in the body and do one last upgrade.

When the Maulers demand their payment first, the Robot mechanical body dissolves and the body says that he's alone and helpless. One of the Twins tells the other to do what Robot wants, and the other Twin puts in the upgrade, a neural link.

Will and Mark go to a BurgerMart and Will wonders if Rick will ever be okay. Mark assures his friend that the GDA will help Rick, and Will blames Mark for not helping him right away. Agreeing, Mark apologizes. Mark says that he's quitting being a superhero because he's messed everything up, and should have listened to his father.

Will realizes that Omni-Man is Mark's father, and tells Mark to quit sulking, study, and pull up his grades. However, he jokingly concedes that Mark lost the hottest girlfriend he's ever had and got what he deserved. Will tells Mark that he got dumped weeks ago and just didn't realize it, and Mark says that he needs someone else to talk to and storms off.

At the GDA, Donald takes Debbie to a control room where Cecil is waiting. Debbie tells Cecil that Nolan killed the Guardians, and when Cecil says that he knows, she slaps him. She asks how he could know and not tell her, and Cecil explains that he couldn't risk Nolan finding out that they knew until they figured out why he did it and how to stop him.

Debbie wonders if Cecil means to kill Nolan, and Cecil says that he's not sure they can. Donald nods and leaves, and Cecil tells Debbie that he only knows of one person who might be able to go head-to-head with Omni-Man. Debbie realizes who he's talking about and says that he can't, and Cecil ignore her and asks where Mark is.

Omni-Man flies to a mountaintop and rehearses a speech to Mark about how he had to kill the Guardians. He insists that it was his responsibility to do it, and figures that Mark can understand it when no one else does. Omni-Man stops, wonders what he's doing, and flies off.

Robot's organic body tells the Maulers that he didn't intend to leave his cocoon, but he met someone. The maulers put a rebreather on him and put a copy of his consciousness into the teenage body. They compensate for the original's dense neuron system, which threatens to overload their power source. The machinery blows up from the power overload anyway, but the copy process is completed.

The teenage body gets up and wonders which he is, and the Maulers tell him that they had to make the transfer seamless. The original Robot is still alive, and the original tells the teenage Robot to be happy it was him that survived and to change the world, and experience everything they ever could. The teenager wonders if they both can live, and the original reminds him that the plan was that the original die, and he wants to die. Crying, the teenager removes the rebreather and kills his original body.

The Mauler says that they know the teenager did an act of mercy, and they do it all the time. They demand the schematics, and Robot the teenager gives them a flash drive from his mobile cocoon. He tells them that it's time for them to go back to prison, and they just laugh.

The teenager points out that he's a 30-year-old genius with a neural link they just installed for him. He activates two Robot drones. The Twins defeat them, and Robot converts the van into a giant robot and attacks the Twins with it.

Omni-Man returns home and confirms that Mark and Debbie aren't there. He finds one invisible GDA soldier in his house, and kills him, and three more open fire on Omni-Man, Omni-Man shrugs off their bullets and kills them, A fourth one tries to run, and Omni-Man shoves her through the door and out onto the lawn. She tries to crawl to the surveillance house across the street before dying of her injuries, and Omni-Man smashes and realizes that they've been spying on him and his family.

Donald is there, and says that it was for the Grayson family's protection. Cecil grabs an energy weapon and shoots Omni-Man, and tells the other agents to run. They do so, and Omni-Man grabs Donald's spine and squeezes. Donald says that it's been an honor and triggers a destruct button, and the house blows up.

Cecil and Debbie are watching from the control room, Omni-Man survives the explosion, and Debbie tells Cecil that Omni-Man is going to find Mark, and she doesn't know who Omni-Man is or what he's going to do. Cecil figures that they'd better find Mark first.

Mark flies up and approaches Atom Eve.

Robot tells the Twins that they will come back to prison with him, and one of the twins grabs some equipment while the other one draws the robot's fire. Working together, one of the Twins completes the gun he's making and shoots at Robot, and the robot shields him. The gun runs out of charge, and the Twins runs as the robot shoots at them. Robot gets a call from Cecil on his comm for all Guardians to come to their HQ, because there's an apocalypse-level priority. Meanwhile, the robot shoots at the clones and misses, blowing a hole in the ceiling.

Will is driving home. Omni-Man lands in front of him and demands to know where Mark is. The teenager tells Omni-Man that Amber dumped Mark, and Mark went to find Eve. Omni-Man tells Will to call Mark, and Will says that Mark's phone is broken. When Omni-Man asks where Eve is, Will remembers Mark telling him that Eve is at her treehouse. With that, Omni-Man flies off.

When the Guardians arrive at their HQ, Cecil tells then to sit tight until he calls on them. Rex demands to know what's going on, but Cecil repeats his order and signs off. The Robot drone is inactive, and the Robot teenager comes in and says that he's more alive than other. Robot says that his real name is Rudolph Connors, and Robot was a drone that he controlled remotely. Rex wonders why Rudy looks like him, and Rudy says that his story can wait until the crisis is resolve.

Cecil's people spot Invincible and Atom Eve flying across the countryside, and that Omni-Man is closing in on their location. Cecil figures that they need to buy some time, and tells his people to "bring the hammer down".

Invincible and Atom Eve land at a waterfall and sit, and Invincible tells Atom Eve that Amber dumped him. He doesn't know who he is or who he's supposed to be, and Atom Eve says that she's saved more lives in the last three days then in the last three years as a member of the Teen Team. She figures that she should call her mom.

The GDA fires an orbital laser at Omni-Man, blasting apart the land nearby. Omni-Man is unharmed, flies up at the satellite, and destroys it as it fires at him again. After he notices that his nose is bleeding, Omni-Man destroys a drone transmitting video of him to Cecil. The hero then heads back toward Invincible and Atom Eve, and Cecil tells his people power up the teleporter.

Rudy tells the Guardians what happened, and Rex asks him why he chose to look like him. Monster Girl realizes that Rudy did it for her, and Rudy says that they're prisoners in their own bodies. Rudy offers to help Monster Girl escape her "prison", and says that he adopted Rex's DNA because he noticed that Monster Girl found Rex interesting. Rex is creeped out.

Monster Girl points out all the crimes that Rudy committed to be with her, and says that she needs time to process it. Samson detects Omni-Man destroying the satellite and shows the others.

Atom eve sees the destruction of the satellite, and says that they should check in with Cecil. Mark tells her that they're both done with all that, and she says that she isolated herself to start over. However, Atom Eve insists that doesn't mean she's going to ignore the world when it needs her. Mark tells her that the world was fine before he came along and will be fine without his help, and Atom Eve tells him that he'll feel worse if he just sits there when he could save lives. Disgusted, Atom Eve flies off.

Cecil teleports ahead of Omni-Man and shoots him with a blaster to get his attention. He teleports away when Omni-Man tries to grab him, and asks why Omni-Man killed the Guardians. Omni-Man says that they were weak, and Cecil figures that Omni-Man had a reason for killing them. Cecil continues teleporting away and back when Omni-Man attacks him, and Cecil asks him about Debbie. Omni-Man tells Cecil not to speak her name, and Cecil points out that Omni-Man is the one who hurt her, not him.

Cecil points out that Omni-Man fooled them all for 20 years, and asks if Mark knows that his father is a murderer. He asks what Mark is going to do when he finds out, and Omni-Man points out that Cecil can't stop him. Cecil admits that he can't, and all he's doing is buying them a little more time. Omni-Man tries to grab Cecil at superspeed, and Cecil teleports back to the GDA control room, part of his tie in Omni-Man's hand.

Three pods crash down around Omni-Man, and Reanimen emerge from them and attack Omni-Man. They knock him down and beat him, and he flies up with them still on him. Another drone watches from nearby, transmitting the images to Cecil and Debbie. Cecil tells Debbie that the Reanimen are dead soldiers, serving their county thanks to Sinclair, who is nearby in a neck brace after Invincible hit him.

Omni-Man kills the Reanimen, and a technician tells Cecil that Invincible and Atom Eve are on the move again and will intercept Omni-Man in four minutes. Omni-Man destroys the new drone, and another one takes its place. Sinclair flies into a rage, and Cecil has his soldiers take him away. Cecil then has the "hail Mary'--the kaiju that Omni-Man fought in Tokyo--teleported to Omni-Man.

The Maulers suture Immortal's head back on his body, and then put the control collar that they built from Rudy's collar on the resurrected Immortal.

Omni-Man flies across the wheat fields, and the kaiju teleports in front of him and knocks him down. Realizing that Cecil is listening via the drone, Omni-Man says that he beat the kaiju already. Cecil replied that they've removed its pain center, juiced it up with every drug and enhancement they had, and it's pissed off from its treatment and blames Omni-Man.

Two news helicopters move in on the fight, and the Guardians watch the newscast. Cecil tells the Guardians to stay where they are, and if the kaiju doesn't work then they're the world's last hope against Omni-Man. Rex figures that Omni-Man killed the original Guardians, and looks at the bloodstain Cecil had his people leave on the wall.

The kaiju overwhelms Omni-Man, and a technician tells Cecil that they can't teleport him to Invincible because teleporting the kaiju temporarily overloaded their systems. They call Atom Eve via her phone on Debbie's suggestion.

As the kaiju prepares to swallow Omni-Man, Invincible and Atom Eve arrive and Invincible flies to his father's defense. Meanwhile, Debbie calls Atom Eve, who tells Debbie that she just missed Invincible.

Invincible catches Omni-Man, and says that it's about time they did a team-up. Meanwhile, Cecil tells Atom Eve to do nothing except go to Guardian HQ. The kaiju grabs Invincible, and Debbie tells Cecil to call the kaiju off. Cecil tells Debbie that he can't, because it's the only remaining weapon he has against Omni-Man and he doesn't know if Invincible is with Omni-Man or against him.

The Twins activate Immortal, but he doesn't come to life. One of them pounds on the Immortal's chest. Immortal remembers bits of his long life, including Omni-Man killing him, and awakens, and goes berserk. The Twins are unable to control him with the collar to kill the Guardians, and Immortal flies off.

Invincible and Omni-Man manage to take down the kaiju, and Omni-Man tells his son that Cecil sent the kaiju after him. He tells Invincible that there's a lot he doesn't know, and the kaiju revives, grabs Invincible, and knocks Omni-Man away. Meanwhile, Cecil gets a report that Immortal is approaching the battle site.

Immortal attacks Omni-Man, taking him by surprise. The helicopters broadcast video of the fight across the globe, and Omni-Man recovers, beat off Immortal, and sees the kaiju slamming Invincible into the ground.

Invincible grabs some nearby power lines and electrocutes the kaiju, while Omni-Man drives his fist through Immortal's stomach. Will, Amber, and the Guardians watch the video, and Monster Girl takes Rudy's hand. Immortal dries his thumbs into Omni-Man's eyes, and Omni-Man rips him in half. Invincible stares at his father in shock, and Omni-Man tells him that they need to talk.
