One Piece: I, Godzilla!

In the Great Pirate Era, heroes rise in droves. The Four Emperors, Seven Warlords of the Sea, Revolutionary Army—these seemingly powerful forces are nothing more than jumping clowns to Imu, who sits upon the throne commanding the Marines, World Government, Five Elders, and God's Knights. Except for Joy Boy who appeared eight hundred years ago. I, Imu, fear no one! ...... "You're right, but this is Godzilla, the titan behemoth 108.2 meters tall, tail 167.75 meters long, weighing 90,000 tons. Super strong perception, powerful body, extreme temperature resistance, and even amphibious on land and sea. Absorbs nuclear energy to grow, atomic breath pierces straight through the Earth's core. Activate Red Lotus form and AAAAAHHHHHHH!!!*
