Ben would've never expected the year to take the turns that it did, he'd assumed that he'd just keep doing what he did best, kicking butt. But after getting caught up in a complicated mess of events and relationships, he realized that maybe school was a lot more eventful than he assumed

One second I was throwing punches at an alien warlord on a sinking warship. The next, reality shattered like cheap glass, swallowing me whole. Now, I'm stuck in a place called New Eridu-a hyper-advanced, neon-drenched city built on the edge of a literal apocalypse. Out there, the rest of the world has been completely eaten by "Hollows," these terrifying, reality-warping localized disasters that mutate anything they touch with a toxic energy called Ether. I don't know the history here. I don't know the factions running the streets, and I definitely don't know how to survive a toxic wasteland. So, to keep a low profile, I'm blending in as a regular neighborhood helper at a retro video store called Random Play. It's a quiet life. The owners are cool, the noodles are great, and nobody asks too many questions. But let's be real. A ten-year-old kid lying low in the final bastion of civilization is one thing. A kid wearing a mysterious, unmapped alien device that can instantly rewrite his DNA into various grim-looking aliens? Yeah. I can't stay hidden forever. Zenless Zone Zero and Ben 10 belong to their respective owners.

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!

Instead, the Omnitrix keeps his human appearance and pushes alien powers into his body. With Chitauri descending from the sky, heroes fighting across Manhattan, and canon events unfolding around him, Adam has only one advantage: he knows what is coming. But in a world like Marvel, knowledge alone is not enough. To stay alive, protect himself, and maybe even change the future. This is the story of a sarcastic outsider thrown into the MCU, where every fight can rewrite destiny and every unlocked alien can change the balance of the world.
