Terina is a red-bellied piranha mermaid and the navigator of the One-Eyed Pirates.


Terina is a curvaceous mermaid above average height. She has wavy red hair that covers her left eye and reaches down to her waist, dark green eyes, and slightly tanned skin. She wears red lipstick and nail polish, as well as magenta eyeshadow. Her back carries the Hoof of the Rising Dragon. Being a piranha, her mouth is full of sharp, triangular teeth. She has a beauty mark to the right of her lower lip. Her tail, which has split in two since she passed the age of 30, is ventrally red and dorsally grey. Her measurements are B108-W60-H90 (B 42.52"-W 23.62"-H 35.43"), making her breasts a J-cup in Japan.

She is commonly seen wearing a black Crimin shirt and blue short shorts. She wears jewelry from her late mother; earrings, a pearl necklace, a bracelet on both wrists (the right is accompanied by a New World Log Pose) and rings on each finger. 

When she was a child, she wore her hair in pigtails. As a teenager, she wore her hair in a ponytail.


Contrary to most mermaids, Terina is hot-blooded and somewhat simple-minded. After briefly being enslaved as a child (mermaids under the age of 30 are the most valuable for slavery), she strove to live her life as a free spirit, never to be held in captivity again. Unlike most former slaves, she makes no attempt to obscure her slave mark, believing that it only holds as much power as she lets it. Despite her resistance to authority, she is willing to listen to her current captain Genesis D. Lantis, whose goals put him at odds with the World Government, and more importantly, the World Nobles.

She generally has little in the way of modesty or manners, often being criticized for this by Edda. She also displays signs of bisexuality. She enjoys eating sweet foods, as well as drinking and partying, displaying a quite hedonistic attitude.

In the past, she was more mild-mannered, but became more aggressive after escaping from slavery. However, she found a friend in Gore.
