Synopsis
After dying in his previous life thanks to the ever-unpredictable Truck-kun, a jaded software developer is reincarnated into a familiar yet fantastical world—as none other than Ben Tennyson himself. But this isn't the Ben you remember. Awakening memories of his past life after a childhood accident at age three, Ben begins walking a very different path. He's not just human—he's a hybrid of Uxorite and human DNA, unlocking immense psychic potential that rivals the likes of Saiki K or Mob. Trained from a young age to control his power, Ben is more focused, sharper, and stronger than ever. At 14, he receives the Chaquetrix—a powerful new device unlike the Omnitrix. Instead of transforming into aliens, it summons female hybrids of alien species combined with Ben’s own DNA. Each “waifu” is powerful, independent, and fully sentient, forming real bonds with Ben while standing as equals, not tools. This AU reimagines familiar faces and conflicts: Gwen and Ben share only a grandfather, avoiding the cousin cliché. Kevin and Albedo may be gender-swapped, giving new twists to their dynamics. No betrayal. No NTR. Just high-stakes action, earned romance, and meaningful connections. Harem elements exist, but grounded in character development and mutual respect. With the Chaquetrix in hand, his psychic powers awakened, and a galaxy of choices ahead, Ben sets out to rewrite destiny—not just for himself, but for everyone.

Chapter 1 - Info

It's a Ben 10 story about Chaquetrix, inspired by TrixTheAlien, a Spanish comic writer who reignited the Ben 10 fandom with his work.

The core concept of Chaquetrix is that instead of Ben transforming into aliens, the watch is designed to summon aliens with hybrid DNA, containing both the user's and the alien species' DNA.

For example, a female Pyronite would have half of her DNA from Ben (human) and the other half from her original species (Pyronite).

So, coming to my story—it's about an orphan (yes, a cliché plot) who was working as a software developer. He gets killed by none other than the almighty Truck-kun and is reincarnated as a baby Ben Tennyson. However, he only regains memories of his past life after an accident at the age of three.

Here's what you can expect from my story:

1.It's definitely a harem.

Yep, we're going all in on that.

2.Ben and Gwen only share the same grandfather—

Not the grandmothers. You know what I mean… hehe 😉

3.Ben is a half-Uxorite, half-human hybrid.

Why not an Anodite? Because that's cliché. I wanted Ben to have different, unique powers.

4.Ben becomes a full-blown psychic due to his Uxorite heritage.

Think Saiki K or Mob levels of psychic power. He starts training from a young age to gain full control over his abilities.

5.After gaining the Chaquetrix, Ben unlocks a new power:

He can use all the abilities of his summoned "waifus" (i.e., like Ben 10K, who could use alien powers without transforming).

6.Ben and Gwen will be 14 when the story begins.

The Chaquetrix arc kicks off when they're both 14, so the canon starts later than the original (which began at age 10).

7. What should I do with Kevin and Albedo?

I'm still deciding whether to keep them male, or give them a gender-swap twist for this AU. 🤔

A female Kevin could bring a fresh dynamic to the group—imagine a tough, battle-hardened girl with Kevin's original powers and attitude, slowly warming up to Ben (or not).

A female Albedo opens the door for a powerful rival-turned-harem member arc, or maybe even a twisted "dark reflection" of Ben's path, with emotional or romantic tension.

Of course, I could keep them both male, stick closer to canon personalities, and still explore epic rivalry, redemption, or even bromance arcs.

So what do you guys think?

Male Kevin and Albedo?

Female Kevin? Female Albedo? Both?

Or even some multiverse mix with alternate versions?

8.Should I let Charmcaster (aka Hope) be a good girl and end up with Ben… or not?I'm torn on this one. Should I give her a redemption arc and make her part of the harem, or keep her as a chaotic, morally gray character? Let me know what you think!

9.There will be absolutely no NTR or betrayal nonsense in this story.

None of that backstabbing, trust-breaking drama you see in those betrayal fanfics on Wattpad—I utterly despise those abominations. This story is about growth, loyalty, and building strong relationships, not tearing them down.

10.About the romance and intimacy:

Yes, there will be lemon scenes in the story—but only after the first major battle against Vilgax. I want to build real connections and character growth first, so the romance and intimacy feel earned, not rushed.

11. About the Alien Waifus:

Yes, the alien waifus will be attracted to Ben—but let me make this clear:They are not just tools, Pokémon, or human shields.

Each one will have her own free will, personality, and goals. They're not just there to fight for Ben—they'll fight with him, grow with him, and have meaningful roles in the story.

They'll be partners, not property. Expect actual character development, banter, drama, and emotional depth—not just eye candy or battle summons.
