"This is not a chapter this is the opening and ending of volume two and one Since I forgot to show it to you." Said Sparta.

Volume 1 Opening

BGM - Ben 10: Ultimate Alien - Opening Theme (2010-2012)

The opening starts with a green hourglass appearing on a black background until a silhouette of a person comes running towards the screen. The silhouette revealed to be Ben Tennyson as he activated his Ultimatrix. The next scene goes from left to right as it shows every alien Ben had unlocked (Original Series Aliens) prior to "Ben 10,000 Returns", along with the Andromeda Aliens, and new never before seen aliens (Omniverse Aliens).

"Omniverse aliens?" Asked Ben confused.

"Aliens from an alternate timeline such as Pesky Dust, gutrot and so on." Said Sparta.

The background shows clips from Alien Force and Ultimate Alien episodes along with unseen scenes. The scene then shifts from the alien background to the camera zooming out of the Ultimatrix symbol, showing Ben Tennyson raising his left arm with the Ultimatrix exposed. It also shows his alien counterparts behind him. The camera continues zooming outward until the title card appears:

Ben 10: Ultimate Alien

BGM Ends

However, the title card suddenly disappears as the scene changes to a different universe, more specifically the World of Remnant. The scene shows the continents, and islands: Sanus, Anima, Solitas, The unidentified Dragon-shaped continent, Menagerie, and the island of Vytal. The three continents: Sanus, Anima, and Solitas each then represent the location of the four respective kingdoms; Vale, Mistral, Atlas, and Vacuo.

The title card for Ben 10: Ultimate Alien reappears with a large black X to the right of the title card, Next, another title card appears in four big letters next to the large black X with each of their respective colors; Red, White, Black, and Yellow. The title card is revealed RWBY.

"And Number one team in the Tournament." Said Ruby.

The scene then changes to where the creators of both shows and the channels that broadcast both series are seen that reads:

Cartoon Network

In Association with Rooster Teeth Productions, LLC.

Presents...

The two title cards with the large black X: Ben 10: Ultimate Alien X RWBY with the large black X separating them, reappear again, as somehow emerald green light and the four colors of Red, White/Cyan Blue, Black/Violet, and Yellow are merging together as the two title cards are fusing into one.

BGM - "This will be the Day" (feat. Casey Lee Williams) by Jeff Williams - RWBY Volume 1 Opening.

"I love the lyrics to this." Said Ruby.

The scene then changes to Team RWBY in front of Beacon Academy along with their friends, Team JNPR, and their two professors, the Headmaster Ozpin and Professor Glynda Goodwitch. Ozpin is observing his students along with Glynda from the main entrance at Beacon. Meanwhile, Professor Paradox is seen from a cliff as he smiles while putting on his goggles, teleporting out of site. In Bellwood, Ben Tennyson, however, transforms into Jetray as he flew towards the dimensional space-time rift that takes him to the universe of Team RWBY. Professor Ozpin then receives a notification on his scroll, Qrow Branwen, as the message reads "Oz, you'll not believe what I've just witness...",

"I've seen it two many times watching this and I still don't believe it." said the dusty old Crow.

the message contains a video of Ben 10 as Four Arms taking down an Alpha Beowolf and it's pack in a forest. Ozpin then responded to Qrow's message, "Excellent, find this boy and bring him to me his power could be useful against the Queen and her pawns." After sending the response, Ozpin smiles as he took a sip of his hot cocoa while sitting in his chair. His second-in-command, Glynda Goodwitch, is too curious and baffled as she was watching the video of Ben 10 as Four Arms decimating the Alpha Beowolf and it's pack, while the next scene transitions to the villains of the RWBY universe: Roman Torchwick, as he shows Cinder, a video of Ben as Heatblast while as the scene ends.

"She must get that Watch." Said Salem thinking of ways to have Cinder try and get close.

The last scene then shows the two title cards finish fusing into one combined crossover logo. The logo is RWBY, but next to the colon is the evolved Ultimatrix symbol as it is placed there as the words Ultimate Alien is placed under RWBY and the green hourglass symbol, with both creators underneath.

Volume 1 Ending

The ending shows Ben Tennyson flying to the City of Vale as Big Chill, the citizens taking out their scrolls and snapping some photos of Big Chill, talking amongst each other of him and the strange green hourglass symbol on his chest. The next scene shows a certain evil woman in a crimson dress along with her two disciples: Emerald Sustrai and Mercury Black, along with Roman's partner Neapolitan

"That's the girl from the Train." Said Yang.

"And Ben's future Yandera Stacker." Said Sparta.

as the four them were in their warehouse hideout in the docks right near the City of Vale. Cinder was smiling malevolently, observing the Ultimatrix symbol on each of the aliens Ben transformed into, her eyes began to glow brightly with half of the Fall Maiden's power she took from Amber. The scene then shifts to images of Ben's friends and family: One image is his parents, Carl and Sandra Tennyson, the next image has the Plumbers and his Grandpa Max, the third image shows his cousin, Gwen Tennyson, Kevin E. Levin, Julie Yamamoto, Azmuth, Eunice, Cooper, and Rex Salazar. Finally, the last image shows Team RWBY, Team JNPR, Team CFVY, Sun Wukong, Penny Polendina, Glynda Goodwitch and Ozpin.

"Fusing? But a Galvan Metamorph Can only fussed with…" Began Max before everyone looked at Penny who look extremely uncomfortable.

"Looks like the cat is out know Penny sorry it had to be revealed like this." Said Ruby.

"Wait you told A civilian." Said James not happy.

"She found out by accident." Explain penny.

giving her the Upgrade Suit, becoming Upgrade Penny, which was similar to Upgrade fusing with Rex Salazar back in "Ben 10 / Generator Rex: Heroes United."

Volume 2 Opening

BGM - Orange - Revolution (Generator Rex theme song)

"I'm glad I have a theme song." Said Rex.

"What is it with you and theme songs?" Asked Holiday.

"Every hero has a theme song." Said Rex like it's obvious.

The opening starts with a shot of the City of Vale, as Ben Tennyson and Rex Salazar were flying together as Upgrade Rex. The two Heroes United then noticed on their right a Bullhead, with their friends and family, Ruby Rose, Yang Xiao Long, in it along with Kirby and Kara on the Warp Star, Ship shapeshifting into a glider for Zwei to fly on, Gwen and Verdona in their Anodite Forms waving at them and flying alongside them as Kevin flew in the Rust Bucket 3.

"Never thought I see a dog fly." Said Glynda.

Rex waves at them along with Upgrade poking out of his shoulder with his head waving at them before speeding away as the Warp Star, Bullhead, and Rust Bucket 3 tries to catch up with them as they head towards Mountain Glenn.

The scene then shifts to Team JNPR, Team CFVY, Ozpin, Glynda, and Amber watching them from Beacon, as everyone wanting to go meet them at the Main Avenue.

The next scene shows the Alpha Nanite glaring at the two Heroes United as the sentient 6 year old microscopic machine tried to get Rex, trying to steal the Omega-1 Nanite that will supply him with the unlimited amount of Nanites to make himself a body and transform into his Ultimate Form: Alpha-Omega. However, Ben and Rex managed to scare him away with their combined powers as Upgrade Rex.

"And this time hopefully do more than imprison him." Said Cesar.

The next scene shows Salem smiling evilly as she sees Nightmare showing her his strongest monsters ever to destroy Kirby and Kara. His four strongest monsters: Masher, Masher 2.0, WolfWrath, and of course his strongest monster, Heavy Lobster, as he reaches his giant hand towards Salem as the Grimm Master professionally and formally shakes it as they're about to conquer not only the World of Remnant, but also the Multiverse that also includes Ben and Rex's Universes as well as any other alternate universes.

"Just as fate has decided." Said Salem.

The next scene shows a flashback of Ben and Rex teaming up for the first time along with White Knight fighting the Alpha Nanite who stabilized himself with the Nanite Population at the Bug Jar in Rex's Universe. After the stabilized Alpha Nanite holds Rex hostage in his left hand, he held his right hand out as a Nanite tentacle latch itself on Ben as Diamondhead on the Ultimatrix, hacking the most powerful Level 20 Alien watch as it went haywire and shut down.

"You did not tell me it hacked the Ultimatrix." Said Azmuth.

"You did not ask." Said Ben.

Later, after Alpha managed to take the Omega-1 Nanite from a weakened Rex Salazar, he transformed into his Ultimate Form: Alpha-Omega: The Beginning and the End of All Things! Ben proposes that he can help Rex beat Alpha-Omega with him transforming into Upgrade, fusing with Rex to form a suit that enhances his 6 Original Nanite Builds with the Galvanic Mechamorph's internal alien technology, beating Alpha-Omega into submission as Rex shot Ben as Cannonbolt out of the Slam Cannon, forcing Alpha-Omega to explode into a red cloud of Nanites as Rex manages to communicate with his "little Nanite brothers" as Caesar arrived, holding a gun to trap Alpha with the help of Rex's Nanite communication to condense Alpha's Nanites into a sphere prison about the size of a baseball with a density of 30 grams per centimeter cube. Ben transformed into Murk Upchuck to transport the trapped Alpha Nanite back into the Null Void as he headed back to his universe before telling Rex that they should do this team up again someday, as the flashback ends.

"That was awesome." Said Summer.

The scene shifts into where Alpha is biding his time, to face his "brother" and of course wanting to copy his friend's alien machine which would temporarily provide him with a suitable host so he can get the Omega-1 Nanite from Rex as he tried to build bodies from some out of Remnant's technology in order to not get bored as Cinder promised him that she will make a body that he can last in without the Omega-1 Nanite.

"So not only can it hack the Ultimatrix but it can also take the forms, this is not good." Said Azmuth.

The ending ends off with Ben and Rex standing in front of Beacon, assembling with their friends and family, Gwen and Kevin as Team 10, Kirby, Kara, Zwei, Ship, Team RWBY, Team JNPR, Team CFVY, Ozpin, Goodwitch, and Amber in front of Beacon, forming the Title Card with Ben, Rex, Ruby, Yang, Kirby, and Kara standing on opposite sides with their signature poses and expressions:
