One Piece Episode 1

Koby is a Marine Captain and a member of the secret special forces unit SWORD. He has pink hair and a cross-shaped scar on his forehead. He began his journey as a timid chore boy forced to work for the pirate Alvida, but he joined the Navy to pursue his dream of becoming an Admiral. He trains constantly under Monkey D. Garp, shedding his cowardly nature to become a confident leader who prioritizes the safety of civilians above all else.

He fights using the Six Powers martial arts style, moving at high speeds to intercept enemies and striking with immense force. He possesses an advanced form of Observation Haki that allows him to hear the "voices" of people across a battlefield, sensing their emotions and presence. His physical strength is sufficient to shatter colossal stone structures with a single punch, a technique he developed by punching the hulls of battleships without using haki.

During the Summit War at Marineford, he stood in front of Admiral Akainu to stop the senseless slaughter of retreating soldiers, buying the seconds needed for the war to end. He later earned the title of "Hero" for his involvement in the Rocky Port Incident. When the Blackbeard Pirates captured him, he escaped his cell on Hachinosu and destroyed a giant stone arm threatening his rescue ship, securing the escape of the other prisoners while Garp stayed behind to cover their retreat.
