When Star gets sent to earth she finds herself with the Tennyson family and makes friends with Ben Tennyson and share some wild adventures. Disclaimer: This is a fanfiction, of course I dont own Ben 10 or star vs the forced of evil,

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...

As a spin-off to Ben 10: Justice Incarnate, Ben is sent to the world of Earth's Mightiest Heroes! With political and cosmic danger on the rise, it's up to Ben and the Marvel heroes to set things straight. (Tying up loose plot holes. Connecting various other Marvel shows. Cover image from Promsien. Not a suicidal Ben introduction! Original opening!)

Academy City. A large city in Japan that is comprised completely of research centers, colleges, high schools, middle schools, and elementary schools. 81 percent of it's population is comprised of students while 60 percent of students are super powered psychics created through Academy City's power development program called Espers. Mikoto Misaka is the third strongest Esper out of that 2.1 billion that dwell in Academy City, being also a prestigious student at the most high class all girl's school in the entire world. Naturally, having such high powers, she has faced many weird phenomenon within the city known for the weird and scientifically advanced. However.. her knowledge about the universe is challenged when she meets a particularly weak esper named Ben Tennyson, whose been living on the streets because he couldn't afford the dorm. And as Mikoto will soon discover.. Ben's true powers.. completely unrelated to his esper ones... are quite out of this world...literally.. ( Also known as とある科学のオムニトリックス Toaru Kagaku no Omunitorikkusu.)

After a battle in outer space gone wrong Ben finds himself back on earth, or so he thought at first but this os a very different earth then the one he left behind, first major difference instad of aliens everywhere there are dragons, and it is not the 21 century because he finds himself surrounded by vikings. what will he do? how will he get back home? (a/n the story takes place right after the end of ben 10 omniverse and right before hiccup decides to destroy the dragon eyes in race to the edge ) full disclaimer i do not own any of the characters just the story.

After the aftermath of his last great battle- he had finally gotten rid of Vilgax, his greatest ever enemy for good, but at what cost? Since that day, Ben 10, the infamous defender of Earth had gone under the radar. He didn't fight aliens anymore, he didn't use the Omnitrix anymore. There was no joy left for him- not after everything that happened. There was nothing. Even after 4 years away from Earth, he found himself wondering- What left? What could life offer him now as he returned home?

What happens when the Ben 10 team fall through a portal during their fight with Vilgax and end up in another world with the Justice League and the Young Justice. But what if the Justice League mistook our hero's for villains? This is the best summary I could come up with, sorry it's not that good. The characters do not belong to me. Ben 10 team belongs to Team Man of Action and the Justice League/ Young Justice belong to Brandon Vietti/ DC

Ben tennyson, saviour of the universe billions of times, stopped the universe from getting destroyed, and stabbed Vilgax with a sword carried by an old man who died. Many more things have occurred for the 16 years old boy, but that's for another time. The universe is now at peace....kind of, there are still bad guys wanting the usual 'take-over-the-world' things and such. Though, with all that's happened to him, being flung into another universe different from his for a second time, is something he won't be getting used to anytime soon.

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.
