A Shift in Time

A Shift in Time is the first episode of Ben 10: Chronolegacies.

Plot
In the delta timeline, the Tennysons are in the Omni-Copter flying to the Biggie Box. Ben says that he needs the new Sumo Slammers Maximilien Monger that instant, and that he needs a big old break from fighting Kevin and the Forever Knight the night before. Gwen agrees, chomping into a piece of potato. She says that she has been practicing magic just in case another villain like Zombozo or Steam Smythe plans to hatch another "master plan". Ben tells Gwen that there couldn't possibly be a villain in the world that could stop their team. He believes now that Kevin Levin, the Forever Knight and Vilgax are gone, he can take it easy and round up the rest of the villains. Suddenly, a purple beam almost hits the Omni-Copter. Gwen teases Ben that something happened, much to Ben's grimace. Max sees a flying figure far in front of the Omni-Copter and believes it to be Hex. Ben says so, saying that Hex's color is red, not purple. The clouds clear and the gang sees Eon. Not knowing who he is, Ben decides to fight. Ben transforms into Stinkfly. He flies up to the top of the Copter and tells Eon to get of the ship. Eon doesn't move. Stinkfly fires stink goop at Eon, only for it to get sent into another time. It comes out as shattered stone. Surprised, Stinkfly flies back inside the Copter and transforms back into Ben. Ben tells Max that they needed to shake Eon somehow, and Max puts the Omni-Copter in full power. Surprisingly, Eon catches up. Ben says that enough was enough and transforms into Humungousaur. Eon whsipers under his breath that that was exactly what he needed. Humungousaur charges for Eon, but Eon dodges. Humungousaur finally decides to use his tail. Unfortunately, instead of hitting Eon, he hits the Copter's engines instead. Eon runs up his tail and touches the Omnitrix symbol, momentarily turning it purple. Eon thanks Humungousaur, and before Humungousaur can swat Eon away, he disappears. Humungousaur transforms back into Ben. Gwen yells to Ben to either fix the engine or give them a save landing. Ben thinks about giving them a soft landing. He daydreams about Slapback, thinking that he can catch them if he made enough copies. But, there would be a lot of craters in the road and he'd fall and be crushed. He thinks about Humungousaur catching it, but there would be an even bigger crater. Ben thinks Heatblast rocketing them down safely. But he thinks that Heatblast will conk out before they get to the ground, and even if he didn't, he might turn the road into tar. So he decides to fix the engine. He imagines Greymatter, then scratches it out because he wasn't in the playlist. Then he imagines Upgrade, then scratches it out because he wasn't in the playlist either. So Ben finally transforms into Shock Rock and shocks the engine back to life. It works, much to the surprise of Max, Gwen and Shock Rock. Shock Rock swings back into the Omni Copter and transforms back into Ben. He says that was weird. Gwen yells at him for almost crashing the copter. Max tells her to stop, and that they needed someone to help stop Eon. Max changes course, much to Ben's sadness. He asks Grandpa Max if they could stop at the Biggie Box real quick, and Grandpa Max tells Ben that they didn't have time to stop, and that he could stop there in his free time. Gwen is stuck on "free time", asking Grandpa where they were going. Max says "somewhere", and the Omni-Copter flies off into the distance.

In the original series timeline, Eon is seen stealing the Enoch Battle Bot from an old warehouse. Eon starts to send it into another timeline, but an electric blast stops him. Eon turns to see Ben as Feedback standing there. Feedback taunts Eon, saying that he needed Enoch's Battle Bot to stop him. Eon says that he could wipe Feedback out with his bare hands. Eon shoots a purple beam at Feedback, but Feedback absorbs it. He says it feels different somehow, and Gwen as Lucky Girl calls out that it was temporal energy from the other side of the warehouse. Grandpa Max walks up behind Gwen with a Plumber blaster. Eon finds them and blasts at them. Gwen shields them and Feedback prepares to fire the temporal blast. Unfortunately, Feedback times out right then and there and transforms back into Ben. Gwen tells Grandpa to save Ben, as she could handle Eon. Max ducks behind some containers, and Gwen runs up to fight Eon. Max grabs Ben and tells him that the Omnitrix has never timed out so fast before. Ben looks up and finds Gwen fighting Eon. Max tells Ben to stay there until the watch recharged while he helped Gwen. Grandpa Max fires at Eon. Eon fires back, turning his blaster into dust. The Omnitrix times back in and Ben transforms into Diamondhead. He shields Max in a bombard of diamonds. Diamondhead swings Gwen over to Eon and they defeat him. Eon teleports away and the Enoch Battle Bot does as well. Diamondhead transforms back into Ben. He says that was weird. Gwen agrees with Ben, because that wasn't Eon's style. Max tells both of them that they are right, and that they needed someone to help stop Eon. Max climbs in the Rustbucket, followed by Ben and Gwen. He asks Grandpa Max if they could stop at the Sumo Slammers Store real quick, and Grandpa Max tells Ben that they didn't have time to stop, and that he could stop there in his free time. Gwen is stuck on "free time", asking Grandpa where they were going. Max says "somewhere", and the Rustbucket drives off into the distance.

In the UA timeline, Kevin is driving to the museum with Ben and Gwen, because both the Plumbers and the Ultimatrix picked up a high-powered energy source being taken. Max suspects it to be the Corrodium that the Plumbers were going to see to picking up that night. Ben says that Corrodium is very powerful, and whoever has it could be making big trouble. They arrive at the museum, where they see the Hand of Armageddon leaking purple. They get ready to fight, because they know it's Eon again. However, the artifact stops glowing, much to the team's confusion. Kevin says that Eon may be too scared to face them. He walks over to the Hand of Armageddon and touches it and Eon's soldiers come out of the Hand and surround Ben's Team. Ben transforms into Four Arms to fight Eon's minions, knocking them into each other. Gwen snares them in the back when they come, giving ample time for Kevin to uppercut them. Some minions manage to slip out of the fray when the three aren't watching, but Four Arms sees them. He tells Kevin and Gwen. Gwen tells him to go after them, and Kevin tells Ben not to get all of them killed. Leaving a sarcastic remark, Four Arms reverts to Goop, who slips under the warriors and transforms back into Ben. Eon's minions find the Corrodium and attempt to pack it up. Ben transforms into Swampfire and then Ultimate Swampfire to fight them, but the minions are too fast for Ultimate Swampfire. Ultimate Swampfire seals off the doors and windows using his seed. Unfortunately, much to Ultimate Swampfire's regret, the minions teleport to another time. Ultimate Swampfire transforms back into Swampfire and then back into Ben. Back at the fight, Eon's minions have Kevin and Gwen pinned, but Jetray comes in and finishes them off with his neuroshock beams. The minions disappear back into the hand, followed by an evil chuckle. Gwen asks Ben if he got the Corrodium, but Ben tells Gwen no. Gwen's Plumber badge rings and Grandpa Max answers it. He tells the team to head back to Plumber Base, and then he hangs up. Ben and his team climb in Kevin's car and zoom towards Max's Plumbing.

In the Omniverse timeline, Albedo transforms into Wildvine and traps Rook, Argit, Fistina, and Solid Plugg in his vines to separate tables. Argit calls out to him, but Rook corrects him and says that it's not actually Ben. Negative Wildvine walks over to the center of the floor with a box and transforms back into "Ben", who then removes a pair of green contact lens, a wig, and a jacket and reveals to the other four that he is actually Albedo. Albedo then says that he could not put one on Rook after he has been impersonating Ben for several days. After Albedo opens the box and inserts a red square into his device that changes its color from green to red, he proceeds to explain to his captives how he pulled off tricking them into thinking he was Ben. Albedo adds that the device that he is wearing on his wrist to transform is not an Omnitrix, but just a device that he needs to stabilize his transformations and he states that he needs one final component for his stabilizer device in order to achieve "Ultimate Power", which Inspector 13 (having just entered the room) accurately guesses that the final component is a Polymorphic Crystal. Suddenly outside of the warehouse, Armodrillo uses a drilling attack that breaks down a wall, which also causes Albedo to fall to the ground and let go of the crystal, and transfoms back into Ben in his regular appearance as Albedo gets up from the ground. Ben jokes that the front door was locked so he had to knock first, prompting Albedo to become very angry to see him. Ben and Albedo fight for the Polymorphic Crystal using their aliens (Ben using Four Arms, Eye Guy, Water Hazard, Terraspin and Shocksquatch - Albedo using Humungousaur, Big Chill, Diamondhead, Goop and Spidermonkey). When Albedo is about to steal the Polymorphic Crystal, Eon teleports in and steals it before Albedo can even touch it, much to the surprise of Albedo, Ben, Rook, Argit, Fistina, and Solid Plugg. Albedo quickly transforms into Arctiguana to trap the heroes (and anti-heroes), but Ben transforms Big Chill and freezes him first. Big Chill transforms back into Ben and calls Plumber base to pick up Albedo while he's still cold. Ben says that if Eon is back, it might be time to call on his alternate timelines.

In the prime timeline, Ben as Ball Weevil is fighting Eon alongside Gwen, Kevin and Rook. Jokingly, Eon asks what did he do wrong. They each recall Eon stealing something - Gwen tells him that he stole the Enoch Battle Box, Kevin tells him that he stole the Corrodium, Rook tells him that he stole the Polymorphic Crystal, and Ball Weevil tells him that he stole DNA samples from an alternate version of himself. Eon blasts at Ball Weevil, but misses. Rook leg sweeps him, and Gwen judo punches Eon. She says a magical spell to trap Eon in metal, but Eon teleports away from it, trapping Kevin instead. Rook uses his Proto-Tool to cut the metal while Ball Weevil reverts to Gravattack and pins Eon down, only for him to stop time. Gravattack reverts to Clockwork where he is immune to Eon's time effects. Clockwork fires at Eon, but ends up hitting a furnace that is rigged to explode. Eon touches Ben on the head, giving him a major headache. Ben transforms into Cannonbolt and curls up, while Gwen shields Kevin and Rook. The building explodes and the team is thrown on the grass outside. Ben screams. Back in the previous timelines, the alternate Bens scream. Ben doesn't see anything and then he passes out.

Transcript
Scene 1

(The Rust Copter is seen flying to Biggie Box).

Ben: Grandpa, are we almost there?

Max: Just about, Ben. (turns around to face Ben) What's the rush, kiddo? You just defeated Kevin Levin and the Forever Knight last night.

(A flashback opens, showing Ben as Rath, Kevin as Crystal Fist, and the Forever Knight fighting.)

Rath: Sorry, Knight. You're not gonna get rid of the aliens. They haven't done anything to you, have they? Have they?! Huh, huh? So lemme tell ya something, Knockoff Knight and Knockoff Me, Knighty-Knight!

(Rath knocks Crystal Fist and the Forever Knight into the portal. Kevin times out.)

Kevin: Get off! This was your plan. I can't believe I worked for you.

Forever Knight: Shut up, child.

(Both Kevin and the Forever Knight look to Ben.)

Both: This isn't over, Tennyson! I will find a way back down here and I'll rip you apart with my bare hands! What? No, I will. No, I will. Shut up, doofus! ''I will destroy Ben Tennyson! I WILL DESTROY BEN TENNYSON!''

(The flashback ends with Rath transforming back into Ben and Ben triumphantly smiling in the past and present.)

Gwen: I'm not so sure that's how it went down.

Ben: Well, I guess it was a little awesome. All in a day's work for a hero.

Gwen: Yeah, but next time you might need help. That's why I'm practicing magic to help you fight the next batch of villains, just in case some more come up with another "master plan", like Zombozo or Steam Smythe.

Ben: Gwen, Gwen, Gwen. (tuts) Now that Kevin and Forever Knight are gone, I can take it easy while I round up the other villains and their "master plans".

(Suddenly, a purple beam almost hits the Omni-Copter.)

Gwen: You were saying?

(They see a flying figure far in front of the Omni-Copter.)

Max: Who's that?

Gwen: You were saying, Ben?

''Ben 10! Ben must stop him with the help of all his friends.''

(Ben Prime transforms into Gravattack.)

Max: Who is that? Is that Hex?

Ben: Nah, Hex is red, not purple. And he's not stupid enough to float right in front of our ship.
