I dont belong here. These words echo in his head like a bell, thrumming repeatedly, like a gong fortelling a horrible omen. Ben Tennyson isn't sure why, or how, but he knows he doesn't belong here. What is here? He isn't even sure why.. all he knows is that it feels like he's living somebody else's life. However, when he is thrust into a world of greek gods and monsters and accused of stealing the Master Bolt of Zeus, his priorities switch to clearing his name. Lucky for him, he has the alien super powers to get the job done.

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.
