50 parts Complete When Ben Tennyson discovers the Omni-Driver-a mysterious Spiral-tech relic that doesn't just transform him into aliens but fuses their memories and identities with his own-he becomes Kamen Rider Omni.
But this isn't a fight to save the world.
It's a fight to stay himself.
Because across the multiverse, other Bens have fallen.
Twisted Bens. Forgotten Bens. Broken Bens.
And one... who chose to stop being Ben at all.
Now, they're hunting him. Challenging him. Testing whether he can stay whole while wielding the impossible power of the Omni-Driver. Each alien he becomes adds to the Spiral-layering thoughts, instincts, fears not his own. Each battle chips away at who Ben is beneath the mask.
As the Spiral tightens, old allies return.
Ben 23, now Kamen Rider Nova, reckless but burning bright.
Ben 10K, the hardened future warrior, now Kamen Rider Sentinel, armored in discipline and loss.
And Gwen 10, reborn as Kamen Rider Wyrd, a mystic fusion of spell and steel.
Together, they stand beside Ben... and against him, when they must.
Because even united, they all know the truth Ben won't admit:
The Omni-Driver is consuming him.
Every alien form brings him closer to unraveling.
And if he loses himself completely...
There won't just be no Ben left.
There'll be no one left to stop what he becomes.
