Arrested Development is the sixteenth episode of Ben 10: Omniverse.
The episode starts the robots from Dimension 12 are attacking Bellwood. Humungousaur and Rook arrive and fight them, but a small child arrives and taunts Humungousaur. Humungousaur brushes him off and the child demands his attention, but Humungouaur ignores him. The child makes the robots stop, which finally causes Humungousaur and Rook to notice him. The child tells Humungousaur and Rook to acknowledge him as their nemesis and destroyer, then activates the robots again.
Humungouaur grabs the child and tells him to call the robots off, but the child flies away on a jetpack and the robots slice a building in half. Humungousaur leaps onto a robot, but he is knocked off by another. a robotic female named Mazuma arrives and joins the kid. The child flies into the battle and aims his De-Ager Ray at Humungousaur, but the two robots accidentally destroy each other and knock the child out of the sky. Afterwards, Humungousaur transforms back into Ben and he and Rook demand answers from the child. The child introduces himself to Ben and Rook as Billy Billions, an old classmate of Ben's. Billy reminisces about always coming in second to Ben and flashback appears to a classroom where a teacher is searching for one of her students, who are raising their hands, to call on and she selects younger Ben instead of past Billy, who was raising his hand. Ben does not know the answer to the answer and continues to lounge in his chair with the other students watching him, which prompts present Billy to say that he was smarter than Ben as past Billy becomes angry. Another flashback appears to a gymnasium wherein the students are beginning to play a game of dodgeball. A female student was selecting the students to be on her team and Ben had activated the Omnitrix and was selecting an alien form to transform into. Ben is then selected by the female student to be her team and he is comforted by her to the other section of the gymnasium while Billy is placed on a group of younger students, which prompts present Billy to state that he was more richer than him as past Billy to angry kick a dodgeball that ricochets and hits him instead. Ben does not remember any of this, but Billy states that Ben will remember a particular event. One night, Ben pursues an unknown villain and corners him in an alley way. Ben transforms into Diamondhead and he holds the unknown villain by the collar. Meanwhile Billy decided to get even and send Ben to Dimension 12 and, while inside of a helicopter, fired off a Dimension 12 portal ray at him, but the ray reflected off Diamondhead's back and hit Billy and his helicopter, sending him to become trapped in Dimension 12 instead. Ben and Rook find his story hilarious and Billy explains that Dimension 12 is a timeless place where all life had been destroyed by the robots. He was there for 5 years and was unable to age, but he became smarter. Billy built a watch that allowed him to control the robots and returned back into Earth. Billy is shocked to hear that Ben is now world-famous and grabs his De-Ager Ray and zaps Ben and Rook with it, which causes them age five years younger.
Ben notices that Rook now has a tail and Rook tells him that the tail falls off at puberty. Ben commands Billy to change them back, but Billy refuses and calls more robots. Ben and Rook run as Ben tries to activate the Omnitrix, but it doesn't recognize his DNA. Ben gets it to activate through telling it that he's afraid of peacocks and transforms into Ball Weevil. Ball Weevil creates a ball and rolls away from the robots, which causes them to chase him, while Rook tries to attack Billy, but he is stopped by Mazuma. Mazuma and Rook fight and Ball Weevil kicks his ball at the robots, exploding it and knocking them into the water. Mazuma knocks Rook away and Ball Weevil catches him on his ball before transforming back into Ben. Mazuma and Billy have left and Ben and Rook try to take the TRUK back into the Plumber's base, but Rook cannot reach the gas, so they take a bus instead. At the base, Max tells Ben that Blukic and Driba are working on a cure. Blukic and Driba are trying to cure Rook and after failing, they admit that they have no idea what to do. Max says that they need to get Billy's gun. At Billions Tower, Billy and Mazuma watch the robots working on a machine. Billy intends to trap Ben in Dimension 12 and then take revenge on all of Bellwood. Billy tries to make the robots work faster, but he accidentally breaks the watch. No longer under his control, the robots turn on him and they open a portal and more robots emerge. Mazuma grabs Billy and they flee the tower.
Ben and Rook arrive at the tower when Billy and Mazuma almost fall on top of them. Billy tells Ben to leave, but Ben grabs him and Mazuma grabs Ben. Rook aims his Proto-Tool at Mazuma. Billy says that Mazuma will release him if Ben releases him. They do so, and Ben figures out that the robots have rebelled. They head up to the robots. Billy wants to see the Proto-Tool, and Ben says that Billy keeps trying to prove that he is the best, but he can't do anything original. Ben and Billy start to fight, but Rook stops them. Ben tells Billy to fix them, but Billy says that they stop the robots first. Ben tries to transform into Shocksquatch, but he transforms into Bloxx instead. The robots hear them and attack. Bloxx leaps at the robots and attacks them. Mazuma tells Billy to not let Ben steal the spotlight, then deactivates. Billy runs into the battle. While Bloxx fights the robots, Billy grabs the De-Ager Ray. A robot attacks him, but Rook saves him. Bloxx saves Rook and Billy fom a robot and Billy sees the Proto-Tool on the ground and grabs it. He cannot figure it out, so he tosses it on the floor and it activates a laser blast which causes the portal to suck the robots and everything else into Dimension 12. Billy almost gets sucked in, but Bloxx grabs him and Rook closes the portal. Rook takes the age gun, and Billy says that he saved the Earth, which pleases him. Bloxx transforms back into Ben. Outside, Ben is 16 years old again and he is interviewed as the Plumbers arrest Billy for unleashing an alien invasion.
