One Piece: The Pay-to-Win Colonel, a Rat Rises to Become Pirate King

From the start, you transmigrate into Pirate King as the Marines' most good-for-nothing captain? Your predecessor colluded with Arlong to oppress the people, got beaten up by Nami, and was supposed to deliver bounties to the Straw Hat Pirates? What a joke! Activate the [Cash King System], and you can grow infinitely stronger just by spending money.

A ten-pull unlocks [Six Powers: Iron Body Mastery], smashing Arlong's sawtoothed blade;

Spend money to get [Top-tier Observation Haki], predicting Luffy's Gum-Gum Gatling three hours in advance;

Recharge to VIP10 to unlock [Warship Modification Privileges], turning a shabby patrol boat into an iron fortress that fires laser cannons!

What? Arlong dares to skim the protection money? I'll hit him with a full set of [Fish-Man Karate: Secret Art: Cash Tsunami], slamming all of Arlong Park to the bottom of the sea!

As Fleet Admiral Sengoku watched radar screens crowded with cash-powered fleets covering the East Blue, and Vice Admiral Garp's iron fist sparked against an invincible shield, Captain Nezumi stood atop a Marine cap made of gold, the disdainful smirk of a cash-spending player from his previous life on his lips.

In this world, having money means you can do whatever you want! From a worthless parasite collecting protection money to the "Cash-Powered Sea King" who strikes fear into the Four Emperors, my bounty poster will always have one more zero than anyone else's!
