Beginning

As the event of one day, when Ben Tennyson and his group discovered the Maltruant aimed to design his own universe using a modified Annihilarrgh.

"You are too late, Ben. The machine's sequence cannot be stopped or canceled," Maltruant gloated, poking Ben.

"Rook, handle Maltruant. In the fifth dimension, his time powers won't work. I'll stop the device," Ben commanded.

"Okay, Ben," Rook agreed and charged in to confront Maltruant.

Ben then transformed into Chromastone. Unfortunately, he couldn't breach the protective barrier around the Annihilarrgh.

"Skurd, do something," Ben commanded.

"As your wish, Ben," Skurd modified his arm into an Alien X arm. With the combined powers of Alien X and Chromastone, Ben pierced the barrier, causing the Annihilarrgh to drop through a hatch, ready to destroy his universe.

In the emptiness before time, the Annihilarrgh fell endlessly until it opened up, forming a black hole. Chromastone reverted back to Ben, and the black hole shrank, releasing a red explosion of energy right in front of Ben and Skurd.

"No, Ben!" Rook shouted from the ship, horrified at the apparent demise of Ben.

"Hahaha! See, I have destroyed your Universe and created a new one in my image. Now I am the ruler of the new Universe. I am the king!" Maltruant roared with laughter.

However, Maltruant's laughter was abruptly cut short when he observed energy rising out of the void and back into the ship, much to his horror.

The pulsing energy was being harnessed by Ben, who cycled through nearly all of his alien transformations, containing the energy before ultimately transforming into Feedback.

"Now, Maltruant, take back your energy!" Feedback shouted, redirecting the Big Bang energy of the Annihilarrgh toward Maltruant. This caused the rogue Chronosapien to implode into bits and pieces.

"Wow, oh my god, Ben, you are really amazing. You even survived the Big Bang. How are you able to do it?" Rook expressed his amazement.

"It's all thanks to the Omnitrix. It seems my intuition and timing help me transform into the right alien, which aids in stopping the Big Bang," Ben explained.

"Congratulations, Ben Tennyson. Your efforts have saved the Universe once more. Why don't you watch how the Universe will be created with us?" The impressed Contumelia invited the two to observe, remarking, "It might be the most interesting one yet."

"This is the most amazing thing anyone could ever see!" Ben gasped, witnessing the creation of the universe.

"MOST AMAZING IS NOT A WORD. It was so exciting that not a single word was made to describe the event," Rook exclaimed in shock.

Ben and Rook stood in awe of the experience as Contumelia revealed several chambers filled with Slime-Biots.

"These are the Slime-Biots, similar to Skurd. They are the most important species in all of creation, carrying samples of DNA and spreading them across the created universes to seed life. That's why I want Skurd to join us on this mission," Contumelia explained the purpose of Skurd and his ancestors.

"Ben, I want to stay with my ancestors to seed life. So, goodbye, Ben," Skurd shared a heartfelt farewell with Ben before willingly detaching himself.

"Goodbye, Skurd. Go live your life to the fullest," Ben and Rook reciprocate the sentiment with heartfelt goodbyes.

Suddenly, Professor Paradox made his appearance. "You've done good work, Ben. You haven't let me down. However, the Annihilarrgh blast has disrupted the fabric of space and time across many Universes, which we need to repair," he explained the need for additional work despite saving the Universe.

Paradox invited Ben and Rook to help him repair the time and space fabric across the multiverse before sending them back home.

Back in Bellwood, Ben, now feeling a sense of boredom after witnessing the creation of a universe, found his present state of peace dull.

"Rook, what are your thoughts about exploring other universes?" Ben inquired.

"I appreciate it, Ben, but we still need to capture some villains," Rook politely declined.

"Since you don't want to, I need to ask someone else. Who should I ask?" Ben pondered, realizing his current single status. Julie, Ester, and Kai had all broken up with him, leaving him feeling lonely.

And he can't even do anything about it. The same breakup situation happened with everyone. They all send the message "Ben, we need to talk."

And when he goes with them, they are the only explanation as to why they are breaking up with him. Different people give different reasons. Julie's reason was, "You know, you have not any time left for romance, all the time fighting aliens, no movie, no travel, and we are just 18, so I am sorry, but I am not able to continue this relationship."

"Ben, since destiny has decided, you will marry Kai, so I can't come between both of you," Ester broke up with him by saying this. Ben wants to explain that don't believe in the game show of Charles Zenith but she runs away before he explains.

And about Kai, although she agreed that she became his wife, in the present she is still searching for the ancient artifacts.

"Well, whatever, since I have already fucked them, and taken their virginity, so now no matter who is married to me," Ben forget about them, and he decided to call Gwen on his cellphone.

"Hello, Gwen, why not travel to other universes together?" he suggested.

"No, Ben. I'm with Kevin now, and I'm busy preparing for the wedding," Gwen declined.

"What's so busy? Just leave Kevin, and we can explore many new universes," Ben persisted.

"Ben, are you an idiot? I'm pregnant, so I can't skip the wedding. And you shouldn't leave before the wedding either," Gwen scolded him.

"Okay, okay, I understand. I'll be there for the wedding," Ben agreed, canceling his plan to explore other universes and he became busy in preparation for the wedding and present for Gwen.

Meanwhile, renowned for his time and multiverse travels, Professor Paradox had ventured into countless dimensions, unraveling the mysteries of the cosmos.

Venturing into a new unknown Multiverse, he is now exploring after the energy of Annihilarrgh broke the time and space fabric. Though Professor Paradox, with Ben's help, repaired it, he noted coordinates with a different energy signature than the Omnitrix Multiverse.

"Marvel Multiverse, so this is its name," Professor Paradox discovered. Going outside the Marvel Multiverse, he found every Marvel Universe linked with a branch.

Filled with awe, he exclaimed, "Wow, the whole Universe is just a leaf in this branch, and this branch is the single Multiverse."

He then realized that the Omnitrix Multiverse is also just a single branch, a detail he had never noticed before, leaving him amazed.

Moving back, if it were anyone else, they would need more time to bypass the Multiverse, but being Professor Paradox, time followed him; he did not follow time. He discovered many branches, forming a mythical Universal Tree by mixing together.

It was a truly amazing sight—nearly hundreds of branches on the Universal Tree, signifying hundreds of Multiverses. In one branch, there were 3000 Universes, meaning at least 300,000 Universes were part of the Universal Tree.

In awe of this new world filled with extraordinary heroes and villains, Paradox couldn't resist adding the location to his Time-Space Map. Recognizing this as a significant breakthrough, his excitement was palpable.

Intrigued by his latest discovery, Paradox reached out to Ben Tennyson 10000, considering him the ideal person to travel with.

Initially approaching Ben 10000, who was married to Gwen, to explain the information about the Universal Tree, Professor Paradox faced a polite decline as Ben 10000 always followed Gwen's orders in this Universe.

Next, Professor Paradox approached Ultimate Ben, who was married to Julie Yamamoto. However, Ultimate Ben declined the invitation, citing Julie's pregnancy.

Undeterred, Professor Paradox sought out Biomnitrix Ben, who was busy training his son Ken Tennyson and daughter Gwendolyn Tennyson, so of course he also declined it.

Frustrated by the unavailability of all the Ben, Professor Paradox concluded, "It looks like I need to go to Ben to explain my theory. If I can't explain it, I won't be able to sleep." So, he decided to visit Ben.

Meanwhile, Ben was also busy in the preparation of Gwen and Kevin's wedding. But suddenly he was interrupted by Professor Paradox.

"Calm down, Professor, Calm Down, I am already here, you can say what you want to say."

"Ben, you won't believe what I've just stumbled upon, it was the most amazing discovery I had ever discovered," Paradox began, describing the Marvel Universe and the vast multiverse beyond. "It's like nothing I've ever seen before, Ben, and it's all part of the Universal Tree. We must explore it further."

Curious and intrigued, Ben asked, "Professor Paradox, what is the Marvel Multiverse? What is the Universal Tree?"

With a smile, Professor Paradox created a hologram of a magnificent tree before them, its branches stretching out into infinity. Focusing on one particular branch, he then pointed to a single leaf.

"Ben, assume this leaf is our own universe," Paradox explained. "This is where you met Grandpa Max with the Omnitrix, one universe where Gwen wields the Omnitrix, and another without any Omnitrix at all—the one where Ultimate Ben resides." He gestured toward different leaves on the same branch.

"Now, assume this branch is the Marvel Universe," Paradox continued, pointing to a different branch. "In this branch, we have never ventured. It's a completely unknown universe filled with its own unique characters and stories. We've yet to discover what it holds."

Paradox then directed Ben's attention back to the massive tree. "Now, assume this tree is the Universal Tree. It holds at least 100 branches, each representing different multiverses, just like Marvel and our own. And the intriguing part, Ben, is that there are 3000 Universes in a single Multiverse, so there will be 300,000 Universes left to explore."

"I understand, Professor. I will contact you after Gwen and Kevin's marriage. Because I am also bored in this Universe, Villains have ended, girls have left me alone. Then, why not enjoy the journey across the Marvel Multiverse." Ben accepted the invitation, but first, he needed to wait until Gwen and Kevin's wedding was over.

After absorbing the concept of the multiverse from Professor Paradox, Ben returned home with a newfound sense of the vastness of existence. While his family was busy preparing for Gwen and Kevin's wedding, he has now started to visit his all love interest no matter if it was his ex or not.

Since he was plan to going on the long journey of the Marvel Multiverse, he wanted to fucked all of them for the memory. While he also met with his daughter Aria Tennyson who was born with Charmcaster. And his son Mark Tennyson who was born with Elena Valadis.

While the Tennyson family was preparing for Gwen and Kevin's wedding in one universe of the Omnitrix Multiverse.
