The Fairy, The Demon, The Star, The Vampire, The Time Traveler, The Killer, The Alien Hero. These 7 people are known in one way or another, as heroes of the Earth from which they hail. Each Earth is different. Some hail from a magical world filled with demons, dragons and monsters. Others come from a world constantly changing due to Temporal Threats. Two come from a nearly identical Earths, and one hails from a world where Japan still relies on lords and swords. Ben has no memory of who he is or where he came from. For as long as he could remember he has lived in Sato City Japan, attending Mizuki High School with his friends. However, things change when one of the students in his class, Hanzo, appears in front of him during an apparent 'date' with the school beauty Erice Tsukiyomi. Hanzo kills Ben immediately, only for Ben to awaken the next day in his own bed barely clinging to life as a strange device activates on his wrist. The Radiant Wars have begun. Now Ben has to fight to kill and rediscover his incredible powers, for there can only be one left when the blood and dust settles.

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.) [ Ben Tennyson X Yang Xiao Long X Harem Girls OC Cryptids X Rosario + Vampire Girls except Yukari] [ Rex Salazar X Ruby Rose ] [ Zak Saturday X Blake Belladonna ] Ben 10: Ultimate Alien, Secret Saturdays, and Generator Rex are owned by Man of Action, Jay Stephens, and Cartoon Network.

(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.

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...
