Ben 10/Generator Rex: Heros United in My Hero Academia

Prologue - Ben 10/Generator Rex: Heroes United in My Hero Academia.

[Ben and Rex stand together side by side.]

Ben: Hello everyone, you probably know me. My name is Benjamin Kirby Tennyson and at the age of 10 I became the owner of the most powerful device in my universe, which has helped me save my entire universe more than once. The device was intended to be used to understand other species and bring peace to the universe, but there were those who saw it as an opportunity to take over the universe. I, with his power, made my universe a better place. However, this won't be a classic Ben 10 story.....

Rex: If you know Ben, you probably know me too.... My name is Rex Salazar and I am an EVO, but not like other known EVOs. As a reminder, EVO is a living organism whose nanites have been activated. Nanites, on the other hand, are microscopic machines that were created in my universe by a group of scientists during the Nanite Project. Five years ago, in the moment of an explosion, nanites entered the atmosphere and spread throughout my world. Since then, nanites have been found in every living being (Except for the White Knight, of course) and are related to their molecular structure. At least that's how it was in my universe....

Ben: You're probably asking yourself, "What's going on here?" True?

Rex: But the answer to this is a bit long.

Ben: So sit back and listen to what we have to say.

Rex: When me and Ben first met, we had a tough fight. Ben: Of course I won....

Rex: *ironically* Would you like what?

Ben: Well, after we came to a truce and sorted everything out...

Rex: Me and Ben had to fight a new and very dangerous EVO called Alpha. Alpha is a sentient nanite created by my older brother Caesar. Caesar created it during the Nanite Project, whose main purpose was to control other nanites. When it was discovered that he was trying to control living beings, he was sent to another dimension, which turned out to be Nothingness.

Ben: For the record, Nothingness is an interdimensional prison for space thugs. Alpha broke free and accidentally dragged me with him to Rex's dimension....

Rex: Me and Ben defeated Alpha in badass style.

Ben: Because we are the best at what we do.

Rex: Well... But there was an accident that turned our lives upside down....

Ben: Exactly, we were sent to a dimension where 80% of the population has super powers called Quirk....

Rex: How did this happen? I'm asking myself this question too.....

Ben: Long story short, we were sent here and now we have to get by, but I'm not too worried about it.

Rex: Me too, because I have someone with me who supports me and I don't feel lonely here.....

Ben: .....but in the end.....

Rex: ....you can't predict everything.

Ben: This is the story of how we became.....

Rex: ......the best heroic duo of all time.

Rex/Ben: PLUS ULTRA!!!

[The action takes place at the end of Generator Rex/Ben 10: Heroes United. When Ben was about to enter the portal as Upchuck with the trapped Alpha in his stomach, Alpha suddenly emerged from Upchuck's stomach and merged with the Dimensional Disruptor. After merging with the Dimensional Disruptor, Alpha caused an overload that damaged himself and transferred Ben, Rex and himself to a new world unknown to them. And basically to transfer their reflections......]
