In the world of My Hero Academia, where humans all started developing abilities beyond the norm of humanity, having powers is everything, and the dream job of every person's wildest imaginations become real.. Super Heroes. Ben Tennyson however, is quirkless, one of the few 'normal' humans to still exist, possessing no super powers to speak of. That all changes however, when a certain device falls from the sky...

During Beacon's Initiation, Jaune stumbles upon a watch that grants him power beyond his dreams while throwing his life into chaos. Now Jaune, Ruby, and their friends must try to survive the insanity of the Omnitrix and the pressures of Remnant. (Eventual Lancaster and other pairings later on)

You'd think that in a world filled with Super Heroes, aliens would be a normal thing. Heck the romanticized version of heroes from old comics has always been that of alien heroes falling to Earth as babies. But not in this Quirk Based Society. Ben Tennyson, aspiring hero student at UA Hero Academy and wielder of one of the most powerful devices in the Galaxy, The Omnitrix, now has to deal with the fact that the nature of his power isn't a secret anymore. His adopted family plagued by reporters, he can't even go on a proper date with Kyoka Jiro. And with tensions on trusting UA's public relations already at a low point thanks to the USJ events and the League of Villains, Not to mention the secret organization known as the Plumbers revealing their hand, things are set to come crumbling down on the Hero in Training. But Ben's got several things on his side. His classmates, his girl friend, All Might, a bunch of super powered alien forms, and witty sarcasm.

Ben 10, wielder of the Ultimatrix, has gone on some crazy adventures including traveling to a parallel universe (Generator Rex). But this one has got to be his craziest one yet. Ben Tennyson has landed yet in another universe, the mysterious World of Remnant, a place that is inhabited by Humans, Faunus, and the Creatures of Grimm. Along the way he'll learn to work together with Team RWBY and JNPR, while saving Remnant from falling to darkness by the mysterious Salem with the help of his new team, Team 10 with his friends Rex Salazar from his previous adventure and Zak Saturday the Cryptid Hero. However, he would learn about his special Destiny that would tie his fate to the entire Multiverse while starting his own Family... A Big Family with a lot of girls... Along with their crazy and Wild adventures. (MAJOR AU where Omniverse didn't happen and Julie Yamamoto is going to be sharing him with Yang and Harem.)

(Please note I will have the Cryptids from Secret Saturdays and Rosario + Vampire Yokais coexist in the SS/B10 world as Cryptids.) (Reminder: I will NOT tolerate Flame Comments. I am trying real hard to not make this boring. The BlazBlue Cross Tag Battle Chapter with RWBY is Canon. And for Smash Bros. Ultimate, like Kirby, I have very good reasons that this will NOT be complicated. Thank You.) P.S. The Ben being an Anodite, I've made it so for the Plot he would be involved with Zak's Past Life as Kur.

It's time to go to SPAAAAACE!!! After getting through his Provisional License Exams, Ben is having a hard time deciding between the Hero Agencies he wants to choose for his first assignment as a Side Kick. With offers from Ryukyu, Endeavor and Mirko Agency, Ben is not short of choices in spite of half the world's hatred of him due to Will Harangue's bad press, but Ben is still having a hard time finding the ideal boss he can learn from. However, he will have plenty of time to decide before that happens, as he and Class 1A are going on a fieldtrip.. and it is the fieldtrip to exceed ALL fieldtrips, as they're going to SPACE. In his first major stint as a UA Teacher, Tetrax takes the entire class and a few teachers on an all expenses paid trip across the Universe to learn from and visit various Super Heroes from other planets, and the final stop? The remains of Tetrax's old homeworld, in the hope that Chromastone, the only Crystalsapien left in existence, can revive it to its former glory. However, the trip isn't all that easy, for there's somebody else besides Vilgax pursuing the Omnitrix, and as he leads the League of Villains into the vast void of space, he won't hesitate to use any means at his disposal to wrench the Omnitrix from Ben's cold dying hands.
