My One Piece Dinosaurs Are Overpowered

Shipwrecked and stranded, Ezaki Ze woke up in the cutthroat world of One Piece, a powerless civilian destined to be swallowed by the merciless sea. In a world where admirals shake islands and emperors command fleets, his survival seemed impossible. Then, the Dinosaur Summoning System activated. His first free summon wasn't a pet, it was a predator: a terrifying Hunting Dragon, its power rivaling a Navy Captain! When a bloodthirsty pirate crew landed, sneering at his weakness, Ezaki Ze simply gave the order. The ensuing massacre left a crimson tide, instantly turning him from prey to apex. But one dinosaur wouldn't be enough. To forge his legend and claim the bounties of the Grand Line, Ezaki Ze needed to summon more prehistoric leviathans, strengthen them into world-shaking behemoths, and prove that in a world of Devil Fruits, true power came from claws, fangs, and scales. The era of dinosaurs had returned, and he was their master.
