RWBY: Heroes United Overview

Hello, and greetings RWBY, Ben 10: Ultimate Alien and Generator Rex Fans out there. If you are seeing this then I should say welcome to the official start of the RWBY: Heroes United series, a crossover between Cartoon Network's Ben 10: Ultimate Alien and Generator Rex by Man of Action and Rooster Teeth's RWBY by the late Monty Oum. This is my first actual fanfic I'll be writing this year. However, since I'm still in High School and writing will take some time, due to schoolwork, but that's okay, I'm looking for a Beta Reader for my help with these stories. I've always wanted to do a Ben 10 crossover with RWBY, because the voice actor, Yuri Lowenthal, voices both 16-year-old Ben Tennyson and Mercury Black. This first story is called RWBY: Heroes United. Ben in this series will take some elements from Ben 10 / Generator Rex: Heroes United, Ultimate Alien itself and Omniverse. Now I know what you're thinking: Why I am using the Ultimatrix in this story?... Well here's the thing, despite Azmuth saying that the Ultimatrix is more complicated to use and the Evolutionary Function or Ultimate Forms are "begging for trouble", but hey I kinda like it despite being less powerful than the prototype and Omniverse Omnitrix.

However, we're going to make some adjustments. The Ultimatrix will still be the same from Ultimate Alien, and will still have the same previous features from the Prototype Omnitrix and Omniverse Omnitrix, along with some new upgrades explained in the first chapter and the rest of the story. Yes, there will be some Omniverse elements, including the Aliens, Life-Form Lock and fail-safe Reviver from the Omniverse Omnitrix, and of course the best part of the classic Ben 10 series, Master Control, not to mentioning of the Sentient Ultimate Forms to avoid the episode "The Ultimate Sacrifice" in the show and the Main Timeline will follow to the alternate Ben 10,000 AKA Ultimate Ben Timeline as seen in "Ben 10,000 Returns" instead of Omniverse. In others words it's an Alternate Timeline, Parallel World or Alternate Universe where Azmuth doesn't take away the Ultimatrix and doesn't give Ben the Omniverse Omnitrix.

Now, I was inspired to write this by some of my favorite authors and their stories. Shout out to KingFrancisX, Swift56, Phoenix Champion, Sai Kunai Blade, Arno Uzumaki, Spirit Soldier, Roth Prime, Bakuganman, blackheart0009, Wolfpackersson09, Shadowlight0982, and finally three authors of Ben 10 crossover series I liked; MegaRDaniels of "Ultimate Ga Kill!", Jade and Q of "RWBBYVerse: Clash of Heroes", Animan10 of "Ben 10 Remnantverse", Enderhunter991 of "Remnant's Shapeshifter", Ultimate10 of "Ultimate Fairy", and finally Bigby the Big Bad Wolf of "Bleach: Ultimate Alien and the remake version.

Now, similar to the author, KingFrancisX, I will make this story like an anime, like he did in United Heroes story because RWBY isn't technically an anime, but hey its anime styled in America not made in Japan, so just live with it. I'll put some openings and endings, and soundtracks via from games or music, to make the story more interesting.

And expect some filler chapters like the bew BlazBlue: Cross Tag Battle where RWBY crosses fate with BlazBlue, Persona 4 Arena, and Under Night In-Birth, but I'm adding Ben 10: Ultimate Alien and Generator Rex to the mix to make it more awesome.

And Ben raising and starting a family will start with 2 aliens, 1 Human, and 1 Hybrid with Yang, Ruby, and Rex as I will reveal to you about along the way.

Also, expect some references from other franchises as they will be considered FICTIONAL in Ben and Rex's Universes and some OC's that I created and borrowed some from franchises.

Anyways, I hope you'll all look forward to this story and probably some future sequels. Now without further or do as Ben 10 always says "It's Hero Time!"

Toy2711: Now Let's get this show on the road!

P.S. if you see Ben 10 / Generator Rex: Heroes United then the Ben 10 Characters and Ben's Aliens will be in Generator Rex Art Style like the Generator Rex's characters especially in Ben's Universe like Rex's, but the Ultimate Aliens and the rest of the Alien Force and Orignal Series Aliens will still retain their appearance of the Ultimate Alien Art Style and the aliens featured in the Heroes United special will be featured in Generator Rex's Art style and Omniverse Aliens will retain their Omniverse art style.
