Marineford in Sharingan, Uchiha Admiral

"I'm planting a divine tree in the One Piece world!" "Marine Admiral!" "The Celestial Dragons' lifelong nemesis!" "Sharingan + Ice Release + Devil Fruit: any good?" "Ancient Zoan - Snow White Wolf!" "The Navy's peak of handsomeness in 800 years!"
With the aim of hunting down the Celestial Dragons, he used a dual identity to rise through the ranks of the Marine Headquarters, becoming the youngest admiral in history!
Borsalino: Compared to that brat, we're ashamed to be called monsters.
Sakazuki: I felt this guy's burning sense of justice!
Kuzan: Compared to that, my fighting style seems incredibly crude.
Sengoku: He will be the future of the navy! A pillar of the navy! (Most importantly, his face boosted his recruitment stats significantly.)
Garp: I have a feeling... this guy will unleash a storm of a great era, just like Roger!
……
Ten years later, the Marineford War.
When the Sharingan's gaze fell upon Marineford, the Divine Tree stretched from the depths of the ocean abyss to the Red Line.
Allen spoke softly.
"The winners don't care what the world is like, they only care about how they make it..."
"And I am the victor!"
"Ruthless and decisive", "Scorching and merciless", "No female lead"
