Setti, Pirate Nemesis!

The Summit War raged, the sky filled with cannon fire. A dazzling figure charged through the crowd, lifted the massive Oz, who had carried a country on his back, and slammed him down from above. Before Whitebeard could even join the battle, half of Marineford had sunk beneath the sea. The pirates could only exclaim: “Holy shit, I'm blown away!”

Raising both hands, the red-haired hunk held up his middle fingers:

“Fuck you! Now this is a party!!!”

Want to fight? From 800 meters away, a predator rushes in, lands a basic attack, then unleashes three hits of Knuckle Down. Press the Attack, Electrocute, Conqueror, and Lethal Tempo all proc in a burst, leaving you at one HP in a second.

Want to run? Glacial Augment pins you down, Fleet Footwork closes the gap, Phase Rush lets me circle you three times, then Facebreaker activates Aftershock. I counter with Grasp of the Undying and trigger Dark Harvest!

With limitless growth, one day even a stray Arcane Comet from your Uncle Sett will be enough to kill one of the Five Elders.

What? You ask me about Aery, Unsealed Spellbook, and Omnistone?

I shrug. Aren't those the runes only sissies take?

Sett, Sett! The pirates' natural enemy!

The Four Emperors? What the hell are they? You, the one called Red-Hair, you better remember this! There's only one redhead on the sea, and that's your Uncle Sett! Next time I see you, I'll yank your hair out! I'll show you what a black hand can do!

A brainless power fantasy. If the author's wavelength matches yours, you'll be having a blast. If it doesn't... well, nothing can be done.
