A Jolt from the Past

A Jolt from the Past is the third episode of Ben 10: Omniverse.

Plot
The episode opens in the past, at the night of the grand opening of Mr. Smoothy. A Megawhatt appears and starts destroying things. 11 year old Ben Tennyson as Stinkfly then comes in and attempts to fight the Megawhatt, but it escapes outside. After Stinkfly reverts back into Ben, he grabs a Mr. Smoothy cup and traps the Megawhatt in it. Thinking that he has won, the Megawhatt escapes the cup and absorbs some electricity in order to multiply, prompting Ben to complain that he doesn't have any electrical aliens.

Ben suddenly remembers that he has Feedback and transforms into him to order take all the power from the Megawhatts, with them all falling asleep. Feedback says that he is in such a great mood, and claims nothing can get him down now. Grandpa Max and Gwen arrive in the Rust Bucket and wrap them up in some of Ben's rubber blankets. Max comments that it's a good thing Ben still needs them, prompting Feedback to tell Gwen to not even think about it.

Skipping to the present, 16 year old Ben arrives late with a smoothie in Max's hangar, while Ben tries to make an excuse about being late. Max sees through Ben's excuses and informs him that he's not working on his own time table anymore. Ben and Rook Blonko take Rook's Proto-TRUK. While at first Ben is disappointed, Rook soon reveals the truck's ability to turn into a small ship.

While on patrol, Rook gets the feeling that Ben is mad at him. Ben corrects him, saying that he's simply bored. Lately, he's been more of a tour guide for Rook than a super hero. Rook, however, is excited about working with Ben, eager to learn if he stacks up to the legends about him. Rook knows that not all of the stories about Ben are true, believing for example that Alien X is just a myth created by Ben's fanbase on the Extranet.

While on patrol, the pair interrupts various alien incidents, and most of them turn out to be misunderstandings on Ben and Rook's part. The few that were actual crimes, the criminals who were committing them were too scared of Ben to continue. The pair eventually spot a human, named Corvo, who is using what looks like an alien tech cell phone that is connected to a back-pack mounted power source. When they confront the criminal, he drives away in his jeep.

Ben tries to transform into Big Chill to chase after the criminal, but transforms Heatblast instead, while Rook pursues Corvo from the roof tops. Catching up with the criminal through flying by projecting fire through his fists, Heatblast suffers an embarrassing and painful landing when the Omnitrix times out, causing him to transform back into normal just above the ground. Questioning the criminal about the alien tech he's carrying, the pair soon discover that both the cell phone and the jeep are powered by Nosedeenians.

Rook and Ben give chase to the small aliens leaving behind the criminal, with Rook in his Proto-TRUK and Ben on foot attempting to transforms into XLR8 but instead transforms into Clockwork. Realizing that he's keeping pace with the pair of Megawhatts in the form of the slow alien, Ben soon realizes that they want him to follow them. Arriving at a dockside warehouse, Ben and Rook soon discover that dozens of Nosedeenians have been taken prisoner.

A pair of armored criminals capture the escaped Nosedeenians and then Ben and Rook. Corvo arrives with Fistrick, the gang's boss, who reveals that he illegally steals, reverse engineers, mass-produces, and sells to the highest bidder alien tech powered by the Megawhatts. After Ben and Rook escape the gang's trap, Ben transforms into Bloxx and battles a few gang members. After the Omnitrix times out and Bloxx transforms back into normal, Ben attempts to transform into Four Arms to fight the group but instead transforms into Gravattack, yet another new alien Ben doesn't know how to use.

To make matters worse, the ringleader reveals an exo-skeletal mecha-suit powered by Nosedeenians. The fight is soon taken outside where Gravattack discovers that he has gravity powers and his own orbit. Rook devises a plan in which Gravattack holds the ringleader still while Rook uses a well-aimed shot to free the Megawhatt prisoners and is successful. The ringleader uses the last of his power to fire a multitude of missiles at Gravattack.

Gravattack uses his powers to redirect the missiles at the ringleader and defeats him. Max comes in with Plumber back up and arrests the gang. Max also reveals that the Nosedeenians have volunteered to power Undertown. With the issue resolved, Rook suggests they go get smoothies but Ben suggests chili fries instead. The pair then fly away, getting into another argument about Alien X.
