BIO

Age: 15

R/C: Whatever skin color or race you choose

H/C: Hairstyle or Hair Color of Choice

Pronouns: I'll make it very vague so that every gender can enjoy reading this, though I might make occasional mistakes in writing.

Appearance: (The appearance is mainly optional, but this is my description.)

A young teen with a lean body type, they mainly wear a white sweater, though it is battered and dirty from years of living in the sewers, along with a long white headband that they mainly wear along their neck.
Y/N also mainly wears a large traveling backpack as a way to not only store items but also in an attempt to fit in with the turtles, copying their shells. They wear black sweat pants and open sandals (the ones Naruto wears), and they keep their kunai attached to each side of their legs.

Personality:
On the surface, Y/N isn't seen as much of anything besides being the quietest and most reserved of the siblings, rarely getting involved in anything unless the turtles are doing it, though once you get past their insecurities, Y/N has a good heart, is very caring, and is willing to sacrifice themselves for the greater good, even though this comes at the expense of Ignoring his own needs.

Weapon: Dual Kunai Knifes

Relationships:

Michelangelo: Being the most positive and open-minded of the turtles, he genuinely cares about Y/N and always attempts to connect with them and include them in activities, much to their quiet nature. Unlike his brothers, Mikey doesn't really have any awkward feelings about Y/N, being relatively chill with them.

Leonardo: the oldest and the "leader" of the group, he tries his best to live up to what he views as a mature kid, much to the dismay of his turtle brothers, but he always feels at ease knowing Y/N easily follows his orders, but other than that, they generally have an awkward relationship as Y/N regularly distances himself.

Donatello: He takes on the teasing sibling role when it comes to Y/N, always teasing him whenever they remotely do anything besides being loners, especially when he follows Leo's orders. He teases him, but a lot of the time, he typically ignores him as Y/N doesn't do a lot besides being "Leo's boring servant."

Raphael: He acts the most negative among the turtles when it comes to the human brother; he tends to bully them a lot of the time, and it's unknown to Y/N why he does it, but he simply brushes it off as him trying to be cool.

Splinter: Although reluctant about Y/N, due to understanding that feeling of being rejected by society, he decided to take them in and leave them at someone's doorstep, but after seeing how Y/N and the turtle tots got along so well together, he decided to place his feelings against humans aside and take them in as part of the family.
