Leo

Leo is a fern green colored anthropomorphic mutant turtle ninja warrior. His eyes have cobalt blue irises with black pupils, but like his brothers when they are shown fighting or being stealthy, they disappear, leaving his eyes white. He wears a blue bandana mask where the tails length range between Donnie and Mikey's. Leo is the most skilled fighter. His height ranges between Raph and Donnie's. His ninja gear includes diagonal straps, brown knee pads and elbow pads, and beige rolled bandages wrapped around his wrists, ankles and fingers. Like the intro states he is the leader and makes the commands which sometimes bothers his brothers especially Raph. Leo is the most serious and disciplined out of all the turtles and is of course their leader. He has a lot of responsibility on his hands, which can sometimes overwhelm him.

Raph

Raphael's wears a red mask and weapon of choice is his twin sai. His most defining character trait is his bad temper and bouts of rage, which he usually takes it out on Mikey. He's also been known to fight with Leo and Donnie, due to their occasional feud (Raph's sibling rivalry, jealousy that Leo is the team leader while Donnie is the team' scientist, mechanism and inventor). Raphael sports a chip in the bottom of his shell that resulted from an accident as a baby. Raphael is rebellious, stubborn, strong willed and hotheaded, Raph loves fighting and does not care particularly if he is injured (thus his rather beat-up shell and mask). Raphael is extremely sarcastic and likes to make fun of his brothers, often coming up with very smart-mouthed remarks. Although Michelangelo is considered the funniest of the team, Raphael is the most sarcastic. He is also the most relentless of the turtles, his relentless ferocity makes him a deadly fighter.

Mikey

Mikey is a yellow-green skinned anthropomorphic mutant turtle, displayed to sport a relatively round, yet somewhat sculpted build. Similar to that of his brothers, Mikey has a very toned physique. Albeit, he is a tad more rounder than his brothers. He is seen clad in his trademark orange bandana mask (which in contrast, have relatively shorter bandana tails than his brothers). Mikey features three big freckles on each his cheeks, followed by prominently large and round baby blue eyes. Mikey wears brown elbow and knee pads atop each his limbs; followed by matching brown bandages residing on his ankle and forearms, followed by a pair of white bandages on his three-fingered knuckles. Tied over his waistline is a light brown belt, which has a pair of holsters wear he can place his duo nunchakus at. Mikey is the youngest of all the turtles, making him the least mature. He is also very social, and wants the outside world (humans) to accept him and his brothers. He is also impulsive, because of a severe case of ADD.

April

April is a petite, slim, pretty and fair-skinned teenager with freckles on her face, ocean-blue eyes with long and thin eyelashes, and shoulder-length fiery ginger hair kept in a low ponytail with right-sided curved bangs. For attire, April wears both a yellow headband and a short-sleeve yellow sports shirt with the shirt having multiple white stripes and the number "5" printed on the front, which is also colored white and it is worn over a dark grey shirt. She wore dark grey leggings under blue denim short-shorts with a noticeable patch on the right back pocket of her shorts April is a smart, strange, and stubborn teenage tomboy with an indie rock vibe. April is also feisty and determined and quite resourceful. She is fiercely loyal to her mutant friends. She is also somewhat reckless too despite her intelligence. She cares about her family.
