Ben 10: Reincarnated to have an alien waifuu harem

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.
