|This article belongs to an alternate timeline or dimension within the Reboot Continuity|
When KO finds himself trapped in a mysterious place, he encounters other Cartoon Network Heroes, and they band together to escape.
In a destroyed city, two shadowed heroes are being attacked by a villain named Strike. Fed up by their hiding, he summons K.O. to fight instead. Just as he's about to destroy him, one of the shadowed heroes saves him, revealing herself to be Garnet. The other shadowed hero is Ben 10, and they run. Strike sends his blaster after them. After brief introductions, the blaster engages them. Ben turns into Four Arms and pushes it back.
The blaster retaliates by blasting off his Omnitrix, preventing him from turning back. Garnet also loses her glasses, which enabled her to focus her future vision. The three escape and manage to temporarily bring down the blaster.
Escaping into a abandoned building, they find numerous other heroes frozen in stone with red X's on them. They do find one hero named Raven, who managed to survive Strike's attack due to a protection spell. She explains that the city they're in used to be a bustling utopia for all sorts of heroes until Strike showed up to destroy all of them, stealing their powers. He then began summoning heroes to destroy from other dimensions.
Raven has also lost most of her powers, only able to levitate. The four decide to attack Strike's lair head on, even forming their team name: O.K. Ben Let's Go Universe.
Using Raven's levitation and Garnet and K.O's punches, the quartet evade traps and monsters sent by Strike and make it to his lair. The blaster shows up once more and corners them. Strike arrives and begins powering up. K.O. uses this opportunity to grab the blaster, figuring that its appearance as a pen would indicate it could create as well as destroy. K.O. restores his new friend's powers and they engage Strike. He sends X energy blasts down that Garnet deflects with rapid fire gauntlet strikes and future vision and Raven uses a blast of dark energy.
When Ben tries to change, he only changes into the various heroes he saw before. K.O. explains that when he used the pen to restore the Omnitrix, the powers that Strike has stolen came with it. K.O. then uses a power fist to launch Ben at the stunned Strike.
Ben then transforms into many heroes as he delivers a devastating final hit, destroying Strike. Garnet reprograms the blaster, and the city, as well as all the heroes, are restored by it. Raven opens portals to their home dimensions, and she and Ben both depart. Before Garnet leaves, she uses the blaster to create a POW card of herself for K.O. and leaves for her dimension. K.O. returns to his home and wakes up in Gar's Bodega. Initially believing he was dreaming, he then discovers the Garnet POW card, realizing that recent events were true.

- In the Crystal Gems' cameo, Amethyst's outfit is colored with the colors of her second regeneration instead of her third.
- Pearl's star is also colored incorrectly in the same shot.
- When Ben hits the Omnitrix, the dial doesn't pop up.
- When K.O. and Garnet fight off Strike's fish, Garnet's fist is colored incorrectly.
- This episode is canon with the Ben 10 reboot,[DR 1] taking place after the events of Omni-Copped from Ben's perspective, as evident by the Omnitrix's Season 3 design.
- This episode marks the third time the Omnitrix is removed from Ben, as this previously happened in Ben Again and Again and Innervasion Part 3: Strange Bedfellows.
- This episode marks the first time Ben transforms from one form to another by pressing the Omnitrix while transformed.
- The current CN logo is used in the title card of the episode but instead of saying Cartoon Network, it now says Crossover Nexus.
- The special is a tribute to the history of Cartoon Network with many Easter eggs.
- The setting for the crossover is CN City, which was featured in a series of bumpers from 2004 to 2007, which has been abandoned since 2007. Therefore, it looks like an abandoned city. The theme from that era can be heard when Strike's blaster undoes the damage Strike himself caused.
- Much like in A New Dawn, Ben goes through a rapid selection of many transformations before choosing one in time to vanquish the main villain. The only difference is that instead of his usual alien forms, Ben switches between a main character from nearly every Cartoon Network original series. Assumingly, the anthem for Cartoon Network Originals, otherwise known as the theme song for Cartoon Cartoons, can be heard during the rapid transformation sequence.
- The themes for NEW NEW NEW NEW and Fridays can also be heard at various points during the episode.
- Logos for Cartoon Cartoons, Fridays, Tickle U, Har Har Tharsdays and Yes! can be seen at various point during the episode, mostly as graffiti.
- When Ben introduces himself to Garnet and K.O., the baseline and guitar rift from the original theme song is heard.
- The soundtrack that is used when Strike summons K.O. is called Welcome To The Nexus. However, in a Twitter promo, the soundtrack that was used is the same music that was used in The More Things Change: Part 1, when Khyber and Zed make their debuts.[CN 1]
- When Ben first introduced himself, he posed similar to how he did in one of the reboot's promotional posters.
- When K.O. first heard Raven's voice, thinking it was Ben's, Four Arms says, "Dude, did that honestly sound like my voice to you". This is an inside joke, as both Ben and Raven are voiced by Tara Strong.
- The team name K.O. comes up with "OK Ben Let's Go Universe", is an amalgam of the names of main character's respective shows.
- Strike's blaster apparently resembling a pen could be a meta gag on how most modern cartoons are drawn digitally, especially how it's able to erase and create anything.
- Ben's form-changing special attack in the end of the special is the "Cartoon Network Punch Time Explosion", which is named after the video game of the same name.[IJQ 2]
- Raven was about to enter a portal that had the original 2003 Teen Titans logo before she changed it to the Teen Titans Go! version.
- In the storyboards, Ben's portal had the 2005 Ben 10 logo with him saying "I can't wait to see my cousin Gwen, whom I love". This is an ironic reference to how in the original series, Ben and Gwen would rarely get along, unlike the reboot.
- The Omnitrix's activation noise that is used in the special is a pitch shifted version of the original prototype, pre recalibrated, Omnitrix activation noise.
- Crossover Nexus was announced at San Diego Comic Con 2018.
- Despite chronologically taking place after Omni-Copped,[DR 1] this episode aired before the release of Innervasion in the U.S.
- In the first teaser trailer, Ben appeared to have the Omnitrix from Season 1.
- This crossover directly connects the reboot back to the Classic Continuity of the Ben 10 franchise, as Rex Salazar from the Generator Rex series and Ben 10-Generator Rex: Heroes United appears as a statue in this episode.
- When asked why Ben Tennyson from the Classic Continuity did not appear in Crossover Nexus, Duncan Rouleau replied to wait, saying that an answer would be coming soon.[DR 2]
- The run time for this special was originally meant to be 22 minutes, therefore the whole idea had to be reworked.
- This is the second crossover not to be dubbed in Hindi after Heroes United.
- The various forms Ben turns into near the end of this episode can only be accessed in the Nexus Realm,[DR 3] meaning he is unable to use them in his home dimension.
- In the final episode of OK K.O.!: Let's Be Heroes, Thank You for Watching the Show, it is shown that Strike has returned to life after his demise, and is also shown fighting Zak Saturday, Randall P. McDuff, and Sunny Bridges. Those cameos were included because no one from The Secret Saturdays, Party Wagon, or Class of 3000 appeared in this episode.
- During the later run of the original series, Ben 10 previously had skits with Beast Boy.
- When asked if Ben 10: Omniverse would have a crossover with Teen Titans Go!, Matt Wayne denied any plans at the time.[MW 1]
- However, he did agree that he thought a crossover would work well and that executive Sam Register likely thought the same.[MW 2]
