Zeo

Zeo is a Japanese wobbegong shark fishman and an officer of the New Fishman Pirates.

Appearance
Zeo is a tall fishman with a strange body, covered in wavy stripes, and "02" tattooed on his chest. Tentacles-like whiskers hang from his face, and unlike other fishmen, Zeo doesn't seem to have ears nor a nose, nor does he have a visible mouth. However, as he is able to speak and listen, it can be assumed he has them. He sports a dorsal fin, and gills on his long neck. His legs are covered by what appears to be some sort of long indument, with a pattern identical to his body's and the New Fishman Pirates' Jolly Roger in correspondence of his right knee. Around his waist is a belt with a round buckle, and his feet seem to be covered by dark boots.

As a teenager, he looked almost identical, with the only differences being the smaller size, the lack of the number tattoo on his chest, the simpler belt around his waist and the pair of loose pants he wore back then.

Personality
Like his colleagues, he believes humans are cowardly creatures. Zeo also despises humans and Otohime's ideals as much as Hordy Jones and the other officers. Zeo appears vicious using threats to force the Fishman Island citizens to comply with the New Fishman Pirates and accept that they can never co-exist peacefully with humans.

Abilities and Powers
As an officer of the New Fishman Pirates, Zeo has command over lower ranking subordinates. He has not yet displayed any fighting ability. However, as a fishman, he is born with the strength ten times that of an average human, and even more underwater; in fact, as an officer of the crew, his strength may be even higher.

Past
While the future officers of the New Fishman Pirates were growing up in the Fishman District, they read about Fisher Tiger's exploits at Mariejois. They cheer the Sun Pirates on thinking that their goal was to destroy humans.

Fishman Island Arc
He was first seen in Noah, along with his captain and fellow officers, commenting on how humans escape so often after Gyro and his crew attempt to flee from the clutches of the New Fishmen Pirates. He is later seen again when Jones and Vander Decken IX formed their alliance. He commented on how they are now invincible on the ocean floor. Later on when the New Fishman Pirates and Decken's men head for the Ryugu Palace, Zeo is seen counting people such as King Neptune and the three princes, possibly trying to figure out how many people would be difficult to defeat.

The New Fishman Pirates split up to go to different places. Zeo goes to the Marine Shopping Mall at the west side of Fishman Island. As the invasion commences, Zeo is seen telling the citizens that coexistence with humans is impossible and forcing them to step on a fumi-e of Queen Otohime.

Trivia
