Hack

Hundredth Dan Hack (百段ハック) is a fishman fighter who joined as a gladiator at the Corrida Colosseum to compete for the Mera Mera no Mi.

Appearance
Hack is a fishman, with spotted skin, scales under his eyelids, sharp teeth, and gills on the sides of his neck. The fishman has a muscular stature, with long flowing hair and a moustache.

Similar to Kuroobi, he wears an open gi with a black belt.

Personality
Hack seems to be a calm and proud person, and follows a dream where a path of friendship may be formed by fighting. For that reason, he will continue fighting.

Jinbe
He is a dear friend of Jinbe, and also shares the same dream - to have a friendship between humans and fishmen. However, the way differs between the two, as Hack stated that he wants it "by fists".

Abilities and Powers
As a fishman, he is at least ten times stronger than an average human, and twice that in the water. However, as he is taking part in the Corrida Colosseum fights, a location in the New World, as well as from the demonstration of a high-level Fishman Karate attack, it's implied that Hack's much stronger than that.

He was able to stop an assault from a large gladiator, by grabbing his opponent's spiked club, and then the man commented that he was unable to move.

Fishman Karate
Hack practices Fishman Karate to fight his opponents with great strength.

Past
At an unknown time in the past, he became friends with Jinbe.

Dressrosa Arc
Hack entered the Corrida Colosseum to compete for the Mera Mera no Mi. For the battle royale, he was placed in Block B. After Block B started, one of the fighters taunted Hack for being a fishman, calling him a freak. Hack then defeated his opponent with Fishman Karate, stunning his shocked adversary and flipping him into the ground.

After showing off his skills, he gained popularity from the crowd and they cheered him on. He attempted to take out Bartolomeo, who was peeing on the side of the ring. Bartolomeo stopped Hack's attack by creating some sort of invisible wall, which blocked Hack's fist and injured it. Hack is then brutally defeated by Bartolomeo.
