Synopsis:

Ben, a perfectly average college student, was bored and rewatching Ben 10. After some time, he went to sleep, never expecting his life to change forever.

He wakes up in a strange void with a once-in-a-lifetime opportunity:
He can reincarnate in a world of his choice… or leave it all to a gacha spin.


After some time, choosing the gacha spin, he watches curiously as it stops at Ben 10.

Choosing a character, he spins the wheel again, and the name Ben Tennyson shows up.

Even better?

He’s not alone.

He has a System.

Not just any system—

The Best Assistant System.

•Guides him through missions and choices

•Rewards him with skills, items, and unexpected bonuses

•Unlocks hidden functions through actions, decisions, and interactions

Reborn into the Ben 10 universe—but not as some random background character—he finds himself in a world where some things have changed, characters are different, and things are definitely not supposed to happen like this.

With knowledge of future events, access to powerful aliens, and a system that clearly doesn’t care about balance, he’s ready for everything:

Vilgax? Strong—but not worth mentioning.

Highbreed? Threat level rising.

Multiverse is in trouble again? Yeah… that’s not new.

And then there’s the other problem…

As bonds form and relationships grow in unexpected directions, his journey becomes more than just saving the universe—it becomes a chaotic mix of battles, choices, and consequences that even he can’t fully predict.

In a world of heroes, aliens, and endless possibilities…

He’s the wielder of the Omnitrix. Ben Tennyson.
