One Piece: The One-shot Superhuman

[Navy + Decisive Killing + No Female Protagonist + System + Equality for All] He is Wood Pierce, a man who subverts the world with absolute power.

He gradually grew into the navy's strongest fighter, decisive in killing pirates, and his conscience was only reserved for kind people.

He publicly executed Rayleigh and personally ended the legend of the Roger Pirates.

In the Battle of Marineford, he killed Whitebeard with one blow, shocking the world.

There is no heroine, no emotional ties, only iron blood and killing.

With a casual swing, he unleashed kinetic weapons that were ahead of their time, launching devastating attacks beyond visual range.

With three heads and six arms, he instantly transformed into a ferocious beast in human form, letting the world see what a monster is.

Marijoa was reduced to ruins, and the Celestial Dragons were barely surviving.

Only under his power can the justice of the navy be fully realized and the world truly usher in a new order.

In the end, all the pirates were destroyed.
