The Tennysons are attacked by a villainous dimension-hopping Omni-alien known only as Alien X. With help from a parallel universe version of Max, they bring multiple alternate Bens and Gwens together to form an alien hero army and combat this threat.
Plot[]
The special opens with Ben and Grandpa Max sitting at a campsite, miserably roasting marshmallows. We learn they are not from our typical dimension, and that in this dimension, Gwen decided to attend summer school instead of accompanying them on their road trip. All of a sudden, a portal opens behind them and a being, who we later learn is called Alien X, arrives and attacks them, prompting Ben to transform into Cannonbolt. Alien X easily overpowers both Cannonbolt and Max; he forcibly removes the Omnitrix from Ben's arm and fuses it to his chest. After he leaves, an alternate Max Tennyson, Maximilian, arrives and repairs the damages, and informs Ben that his Omnitrix is unfortunately gone forever. Maximilian leaves their dimension on his ship, the Rustbucket. He records a captain's log of his recent mission to stop Alien X, expressing frustration as to why he always arrives one step too late. He decides to pull up his map of the Omniverse and find an untouched dimension to get to first before Alien X. After he selects one, "our" dimension, his ship gets attacked by Phase Parasites in the dimensional hyperspace. Maximilian is forced to activate his ship's self-destruct sequence and make his final warp to that dimension.
Meanwhile, in that dimension, Ben is fighting Zombozo as Shock Rock on the roof of the Rustbucket, being driven by a hypnotized Max. As the fight goes on, a tied-up Gwen manages to free herself and she and Max put a stop to Zombozo, much to Ben's annoyance. Once they return to their road trip, Max and Gwen eagerly talk about what stops to see next, while Ben is unenthused. He says he might need a break, which Gwen eventually figures out means that he doesn't want to be a hero with the two of them anymore, and fly solo instead. Ben wishes he could show off his aliens' true potential, and thinks he can't when people are getting in his way trying to help. Their conversation is cut short when Alien X appears in front of the road, flipping the Rustbucket over by simply letting it hit his outstretched hand. As Max and the kids recover, Alien X advances toward them. Ben transforms into Four Arms and tries to fight him, but struggles against Alien X's telekinesis. The Omnitrix times out and recharges immediately, and Ben transforms into Heatblast. Alien X dodges all of Heatblast's fire with teleportation. The watch times out and recharges again, and Ben transforms into Humungousaur, whose attacks Alien X blocks; though he manages to knock him back once. As he is thrown against the Rustbucket and times out, Ben tries stalling. Gwen and Max decide to help Ben, whether he wants it or not, and bait Alien X to the front of the road, where an incoming truck is driving at full speed. It runs into him, though Alien X easily destroys it.
The Tennysons flee to an abandoned factory and catch their breath. Ben argues with Gwen that he was going to defeat Alien X if she and Max had not gotten in his way. All of a sudden, a green portal flashes and out comes Maximilian. Gwen assumes he is from the future, but he corrects it to "alternate dimension". Ben impatiently transforms into Diamondhead, but Maximilian explains to him that they are all part of a larger "Omniverse" that Alien X is storming through, wanting nothing less than the collection of every Omnitrix from every Ben Tennyson. He reveals that he also failed at keeping his own Ben safe from him. We are shown Maximilian's Dimension at the time of Alien X's arrival; his Ben refused to warp, gallantly running off to fight Alien X, later being defeated and killed. Now, Maximillian won't allow himself to fail again, and plans to make a final stand to permanently stop Alien X in our Ben's dimension. He and Diamondhead clash; the latter not wanting to be used as bait; and the former angry that Ben doesn't understand the importance of his safety. Alien X interrupts them and uppercuts Diamondhead to the second floor, where he times out. Maximilian gives Ben an opportunity to run away; Alien X locks him, Max, and Gwen behind a door.
Ben runs away in fear until the Omnitrix recharges, turning into Rath and fighting Alien X outside in a forest; however Alien X's teleportation, telekinesis, and other skills prove to be too powerful and Rath loses hard. Ben times out and Alien X grabs him by his arm. Just as he prepares to take the Omnitrix, Maximilian interrupts and shoots Alien X with a blast from his arm cannon, the feedback accidentally making the Omnitrix detach; dropping Ben out of Alien X's grip, but allowing Alien X to fuse the watch to his chest and leave through a portal. Ben is devastated. Maximilian surmises this dimension's Omnitrix has a failsafe release and tells the Ben to be grateful he still lives. Gwen tries to come up with a plan to get it back, such as finding a dimension where Ben hasn't yet found the Omnitrix, but Max tells them that without his ship, they're stuck. Suddenly, another portal opens and out steps what Maximillian identifies as a Crystalsapien. It introduces itself as Chromastone, before reverting into a teenage version of Ben from a different dimension. He, like Maximilian, has been tracking Alien X through the dimensions and also frustrates over getting to him too late. However, he also has the assistance of an intergalactic law enforcement agency known as the Plumbers (something Max is surprisingly aware of); and that with his portal generator, he has no transportation problems. Maximilian offers to join this Ben (aka Alien Force Ben), and Gwen suggest that since he still has an Omnitrix, they can use him to lure Alien X back to this dimension. Maximillian believes the plan will never work because of Ben being a stubborn brat, which offends Max. Ben breaks up all the arguing when he agrees with Gwen's plan, believing two Bens can stand a chance against Alien X.
While Maximilian searches for another Omnitrix using the portal generator, the others set a trap for Alien X. Ben picks the location: his favorite (though currently abandoned) amusement park Adrenaland. The Tennysons and Chromastone build their trap using attractions throughout the park. After they are done, Gwen pressures Alien Force Ben to tell her about his dimension's version of her. He tells her that she grows taller, loves magic books, and has a crush on Kevin, which disgusts her. When Alien X eventually arrives in search of Alien Force Ben's Omnitrix, Ben transforms into an alien named Big Chill and orders the other Tennysons to activate the trap. However, the trap fails, Big Chill is defeated, and Alien X decides to rethink his prior mercy and take Ben's life. Before he does, Maximilian returns with another Ben from another dimension. This one looks indistinguishable to the other teenage Ben, but has a different watch. Ordering Maximilian to take Ben to safety, he (Ultimate Alien Ben) turns into an alien named Ampfibian, teaming up with Alien Force Ben as Chromastone to take on Alien X. As Gwen and Ben watch, she makes him realize they need to expand their family even more. Ben abruptly takes the portal generator from Maximilian and pulls him through a portal to find more Bens; Gwen understands because the only person who Ben will listen to is himself. Alien X lifts up an entire Ferris wheel and almost flattens the rest of them, but Chromastone stops it and Maximilian and Ben return with reinforcements.
The reinforcements are two new alternate Ben 10s (Original Series Ben and Omniverse Ben), as well as a Gwen 10. They all transform into their own aliens and try to take shots at Alien X, but he manages them all. As Alien Force Ben admits that they are not winning, Alien X lifts up a giant rock and throws it at them, forcing them inside a cave and blocking the entrance. They all sulk over not being able to put a dent in Alien X. Ben realizes that they all have the same problem: they're too hard-headed and try to take on Alien X one at a time. In order to win, they have to synchronize their powers and work together, as a team and as a family. They all put their hands together and yell "It's Hero Time!". Maximilian gives Gwen and Max some weapons to join in the fight, while all the alternate Bens (and Gwen) transform. With a newfound attitude, Team Tennyson busts out of the cave entrance and makes their stand against Alien X. They fight against him, protecting their teammates when in danger and pressuring Alien X to focus on defending against attacks from all directions. Eventually Gwen 10, as Ripjaws, pulls Ben's Omnitrix out of Alien X's chest, and Ben finally takes it back. He turns into Heatblast and teams up with Original Series Ben, also as Heatblast. The team regroups and attacks Alien X, pulling off as many Omnitrixes as they can before he pushes them away. Eventually, he is left with only one Omnitrix left, and he stands off against Ben, as Four Arms. The two run at each other, and Four Arms triumphs in the clash with his "Quadruple-Decker Knuckle Sandwich", finally defeating Alien X.
Alien X laments that he was "so close", to which Ben says he never stood a chance because he was trying to do it all on his own. Alien X then detransforms, revealing he was also an alternate version of Ben this entire time. "Ben X" confesses that he doesn't belong to any of their dimensions, and that after an encounter with his version of Vilgax that got his version of Max and Gwen killed, he decided that his family was wrong in trying to help him. He would have proved that going it alone is the only way to succeed, by travelling across the omniverse to ensure every other Ben feel the same pain that he did. Maximilian then tells him that he could always start over, if he had people willing to accept him as his new family, offering himself. Ben is appalled, but Maximilian explains that while this Ben needs to pay for his crimes, he isn't beyond help, and that the people who love Ben would offer him a second chance, were he in this Ben's shoes. Ben X says he'd rather go back to the Null Void, but Maximilian promises him that after his sentence, they'll both be spending some quality "grandfather/evil-grandson time". Maximilian opens an exit portal and thanks Team Tennyson for reminding him that everyone needs a family. All the alternate Bens and Gwen celebrate saving the omniverse and say goodbye as they exit. After everyone leaves, Max tells Gwen that they should probably give Ben some space, but Ben surprisingly hugs them and tells them to never leave him again, saying he'd rather be with them than ever consider riding solo. Max informs them that that means Team Tennyson is back on the road!

Max: How do you know who I - who we are? Chromastone: Bet you've never been this alien before, huh? (Ben shakes his head no before Chromastone reverts back into human) Alien Force Ben: Don't worry. You'll grow into him. Probably. Ben: Are you, me? (Alien Force Ben nods his head) Gwen: No way! Ben: Obviously way. No let him, I mean me, I mean him, speak!

But at least this Ben survived. You think I'd be use to it all by now but... (Looks at picture of him, Ben, and Gwen on summer vacation 6 years ago) Anyway, this isn't about revenge anymore. Not when there's still Bens to save and Omnitrixes at stake. As for Alien X. Have to figure out why I'm always one step behind him. (Pulls up map of the multiverse). Find a dimension he hasn't hit yet. Get there before he does and wait for him. There. ID coordinates: 27998.3.

Max: True, but clearly he has rugged good looks, cool gear, and naturally charisma. He looks like some sort of a- Gwen: -Future Max. Maximus: Alternate dimension, but close enough. You were always the smart one. Ben: Ugh. (Transforms into Diamondhead) Ugh. I don't have time for this. Maximus: Make time kid. The future of the Omniverse is at stake. Gwen: The Omniverse?

(Everyone looks at Diamondhead) Diamondhead: What? I know things. Maximus: He's a mystery alright. scouring dimensions for one purpose - to collect every Omnitrix he can get his grubby hands on. I tried to keep my Benjamin safe, but I failed him. Diamondhead: Your Benjamin? Gwen: What happened. (Flashback) Maximus: We need to warp, he's too powerful.

Gwen: Ben! Max: Did he hurt you? Ben: My watch! How? Maximus: A failsafe release. Not every dimension's Omnitrix has one. I've seen it before. Be grateful you're still here to miss it. Ben: Grateful, I lost everything! You got to help me get it back. Maximus: No I don't. Thanks to your hard head, Alien X is one step closer to his ultimate goal.

Alien Force Ben: Adrenaland? Ben: It's Awesome! Please tell me you have them in your dimension!? Alien Force Ben: Yea-No. Ben: ....What a terrible terrible world.

The End of Alien X
Continuity[]
The Tennysons acknowledge that the summer is ending, indicating that the events of this special take place several hours after Ben Gen 10.
Gwen alludes to Zombozo's previous attempt at stealing the Rustbucket in Bomzobo Lives while Shock Rock and Zombozo bring up the latter's clown car from Clown College.
In response to the thought of Ben being bored, Gwen says "not again" as a reference to the events of Ben 10: Versus the Universe.
When Max states that Adrenaland is "closed for the season", he expresses relief that no one will get caught in the crossfire of Team Tennyson's fight with Alien X. This statement stems from the fact that pastbattles in Adrenaland parks see civilians being put in danger due to Ben's aliens or enemies, which often result in Team Tennyson being banned from each location.
Allusions[]
The title is a combination of Alien X's name and the word "extinction". Curiously, Original Series Ben says this pun unpromptedly, when Team Tennyson confronts Alien X with reinforcements.
As a tribute to the Classic Continuity, this special features an enormous amount of references to concepts and elements taken from its associated series:
The plot shares similarities to And Then There Were None and And Then There Was Ben, as multiple versions of Ben (including a Gwen 10) are shown working together against an pandimensional villain.
Much like how the first episode of the Original Series takes place in a campsite at night, the beginning of the final episode of the reboot takes place in the same setting.
The idea of an alternate timeline where Ben and Max go on their summer road trip without Gwen is a repurposing of an earlier premise for the Original Series.[pop-up 1][1][pop-up 2]
The running gag of Maxmilian being mistaken for a future version of Max is likely a reference to this.
When Alien Force Ben mentions the Plumbers, Reboot Ben suggests a better name for the organization would be "Alien Force", referencing the name of the seriesAlien Force Ben is meant to represent, as well as Classic Ben's longest-running team that spawned from said series.
Ben is reluctant then later willing to join his team in putting their hands together, which mirrors Classic Kevin during the ending of Ben 10 Returns: Part 2.
In the former case, all the Bens and Gwen 10 shout their signature catchphrase, "It's hero time!", just as Classic Ben also did in during the ending.
When both Ben and Original Series Ben turn into Heatblast, Ben says "Heatblast is a classic", which is a nod to the Original Series, where Heatblast originated.
Original Series Ben says "Smell you later!" before returning to his dimension, a reference to the same line said in Goodbye and Good Riddance.
Many of the extradimensional characters' home dimensions also have elements that mirror events within the Classic Continuity:
Alien Force Ben mentions that his Max "was" a Plumber, mirroring Classic Max's supposed death in Max Out.
Alien Force Ben mentions his Gwen taking interest in both magic books and Kevin, mirroring Classic Gwen's affinity for magic and love for Kevin.
Original Series Heatblast indirectly mentions that his version Gwen operates under the persona "Lucky Girl" and can cast spells, just as Classic Gwen does.
The interdimensional coordinates for the dimension featured in the prologue is "12041.5". This designation is named after "Earth-12041", which is the official reality number for the 2012 Marvel Animated Universe that Man of Action had previously worked on.
In the Latin American Spanish dubbing of the special, Maximilian's Dimension Ben is voiced by Isabel Martiñón (10-year old Ben), even though Ben as a teenager is voiced by Carlos Hernández. AF, UA and OV Dimension Bens do however have the corresponding voice actor.
When Omniverse Ben first activates his Omnitrix, the square faceplate pops up as part of the core instead of sliding upwards to reveal the core.
When Bloxx transformed into a dome, he was multi-colored, however in another scene, his dome was all red.
In the close-up shot during the group transformation, Ultimate Alien Ben's jeans are colored green instead of blue.
When all of the alternate Omnitrix users transform, Ultimate Alien Ben, Original Series Ben, and Gwen 10's Omnitrixes don't pop up.
When Bloxx rolled towards Team Tennyson, for one frame his body was cut off.
After Team Tennyson defeated Alien X, Ripjaw's waist stripe was missing.
When Alien Force Ben congratulates Ben on saving the Omniverse, Ultimate Alien Ben and Alien Force Ben both have the same Omnitrix.
When Dimension 12041.5 Ben detransforms, his Omnitrix is still green.
When Ultimate Alien Ben activates his Ultimatrix first time, the Ultimatrix core does not pop up.
When Alien Force Ben and Ultimate Alien Ben selects aliens, the holograms are faced away from them.
After Original Series Ben says "Smell you later!", Reboot Ben said that he would steal the line. However, Reboot Ben previously said that line to Steam Smythe in Ye Olde Laser Duel.
Strangely, despite entering Maximilian's dimension with nine Omnitrices and managing to kill Ben from that dimension, along with many other alternate Bens, Alien X is seen with only nine Omnitrix symbols when he enters the Dimension 12041.5.

Trivia[]
This is the final episode of the Reboot. A possible new iteration of the franchise is currently in its planning stages.[DR 3]
The purple portals which Alien X opens for dimension traveling are similar to the time portals from Roundabout Part 1 & Part 2 and Ben 10,010.
The blaster on top of the Rustbucket in Ben X's Dimension resembles the blaster on the toy version of Rustbucket released by Playmates Toys in 2017.
The name of this episode was first revealed when Becky Lau revealed a background image from this episode which she worked on.[BL 1]
A multi-dimensional crossover was first hinted by Duncan Rouleau when dropped vague hints on what to expect for Season 5, mentioning appearances by Alien Force Ben, Omniverse Ben, and Gwen 10.[DR 4]
Duncan would eventually drop hints at an explanation as to why Ben Prime did not appear in Crossover Nexus[DR 5] and a possible connection between the two continuities being explored.[DR 6]
Likewise, it was first confirmed at a press release that multiple versions of Ben from past series would appear.[2]
The first footage of the special was revealed on Cartoon Network's YouTube channel on March 22, 2021.[CN 1]
The reason why the alternate Omnitrix users used one or two aliens during the special was due to time constraints and design costs.[DR 7]
Steve Blum was not asked to reprise his role as Original Series Heatblast.[SB 1]
Ana Lúcia Menezes's Dedication
In Brazil, this episode marks the final time Ana Lúcia Menezes and Júlio Chaves, the dub voice actors of Gwen and Max respectively, played their roles. They both unfortunately passed away in 2021.
In the Brazilian version, there is a dedication to Ana Lúcia Menezes in the end of the special. It's possible that there isn't one for Júlio Chaves because editing of this episode was finished before his death.
Duncan initially stated that there were no plans for either Ripjaws, Chromastone, or Ampfibian to appear in the reboot.[DR 8][DR 9][DR 10] The fact that they make appearances in this movie event indicates that these statements were made in order to prevent spoilers.
Heatblast & Cannonbolt are the only aliens to physically appear in the first & last episode of the entire Reboot Continuity.
Originally, Cannonbolt was to be used instead of Rath.
The scene where Ben and Maximilian arrive with the alternate Bens up until Alien X trapping the Tennysons inside of a cave was storyboarded by Sarah Visel.[SV 1] In the storyboards:
Ultimate Alien Ben's Ultimatrix is correctly positioned so that the dial is at his wrist.
Ripjaws is depicted with an Omnitrix symbol on her left pectoral, as was the case with Ripjaws in the Original Series.
Ripjaws lacks her water containers.
The sequence where Big Chill, Ripjaws and Ampfibian attack Alien X is lengthier. Originally, Big Chill dodged Alien X's rays and there was another shot of Ripjaws jumping across floating rocks.
The shot where Bloxx recedes his dome form is noticeable less zoomed-in than the final shot.
When Original Series Heatblast and Ben check in on Big Chill, he is in his cloaked appearance.
When Alien X lifts a large boulder over the Tennysons, Big Chill is visible, whereas the final episode has him obscured by Bloxx's arm.
Notes[]
↑Duncan Rouleau originally stated that the four alternate Bens featured in this special are the same as the Ben Prime from the previous four series.[DR 1] However, he later rescinded that statement, stating that they are from alternate timelines.[DR 2]
