At the Same Time, They Traveled Through Time, But the Villain Scientist

We've traveled through time, and we're still in the same world.

Bad news, abilities can't be shared.

Good news, most of the people we traveled through are well-known figures, and they're all scientists with incredible research and development capabilities.

But why are most of them villains?

(Naruto's Orochimaru, Ultraman Masaki Keigo, Under One Person's Avatar, Marvel's Harry Osborn, Kamen Rider Dai Shocker, EVA, Robosuit, Infinite Terror, Stone Age, The Three-Body Problem, The Wandering Earth, Gundam...)

In short, it's a story about these tech-savvy characters traveling through time together, and a group of scientists using cutting-edge technology to change the world.
