In a dark twist on the beloved Ben 10 universe, Ben Tennyson discovers the ominous Carnitrix, a cursed type of Omnitrix created by the malevolent Azmuth and Vilgax. This terrifying watch unleashes horrific transformations, forcing Ben to confront his inner demons while he unwittingly becomes an instrument of chaos and destruction. As he grapples with the trauma of losing loved ones, including Max and Gwen, Ben finds himself unable to escape the watch's control. However, a coalition of alternate versions of Ben Tennyson from across the multiverse comes together to save their friend and restore balance. Will they succeed in freeing Ben from the Carnitrix's dark grip, or will the shadows of the past haunt him forever?

(I don't own Ben 10, DC Comics or anything else related to them in the crossover. All Arts belong to the original creators) The story of Ben Tennyson was the same as his prime version, until the fight with Vilgax. After the final fight in secret of the Omnitrix, instead of returning to earth with Gwen, Ben decides to stay with Tetrax and Azmuth in space, to master the Omnitrix and kick butts across the Universe for fun... so watch out because it's Hero Time!

We all know the classic story of Izuku Midoriya. A quirkless boy who dreams of being a hero like his idol All Might and upon receiving his power from All Might and becoming the 9th wielder of One For All and defeats Tomura Shigaraki, saving the entire world from his wrath. But this story however deviates from that destiny. Instead, this is the tale of of a different torch, one that stems from the world beyond. A torch that carries hundreds upon thousands upon millions of Alien DNA samples from across the universe, a watch; The Omnitrix. Ever curious to see what would've became of Izuku Midoriya had he inherited the Omnitrix instead of One For All? The path he would've been sent down instead of All Might's successor? To face the legendary Ben 10'000's enemies and inherit his legacy instead? Well, with this story; I hope to answer all of those questions! I hope you'll enjoy this story as much as I do! And for those wondering, yes; this is unfortunately a reupload of my original first story due to my first account getting banned. But don't worry, I won't give up! I'll just keep on writing like I always have before with a smile on my face! It's time to Go Beyond, PLUS ULTRA!

Every Ben Tennyson throughout space and time has had his fate intertwined with that of the Omnitrix, except for one. After fighting alongside his alternate counterparts to defeat Vilgax, Ben decided he'd fight alongside his grandfather by joining the Plumbers Academy. The only question is, where did the Omnitrix of that universe go? In a universe where Ben 10 was a mere media franchise, Izuku Midoriya, a 16-year-old Japanese video game otaku, had a dream to become a superhero. However, he knew that extraterrestrial life was impossible, so he studied to become an astronaut. After an accident, Izuku, his childhood friend Katsuki Bakugo, and his rugby teammate Eijiro Kirishima ended up at the far end of the universe in a cold shuttle. With Eijiro's chivalry, Katsuki's short temper, and Izuku's knowledge as an otaku, they worked tirelessly to survive and return home. During their journey, they met allies, gained abilities, and even... an OMNITRIX!!!???
