First Appearance

Rise Of The Turtles

April O'Neil is a deuteragonist in Teenage Mutant Ninja Turtles. She is portrayed as a best friend of the Turtles and the love interest of Donatello, who first met them when when they saved her from the Kraang, who needed the psychic Kraang-like powers she had gained when she was born for their invasion on Earth. She is very sweet, mature, and brave. Her tessen makes her a very skilled (almost full-on) Kunoichi.

Not Your Average Teenage Girl

Official Description

"Most people think that I'm a regular, shy 16-year-old. My friends and I hang out, play video games and eat Pizza. Totally normal if you think of it that way. Except.... my friends are mutant ninja turtles who live in the sewers and the closest thing I have to a father figure is a gigantic rat. So yeah, maybe not so normal. I also keep a record of strange happenings in town on my laptop. Strange, huh? The closest thing I have to a friend is Donnie. He's been there for me when I'm down and stuff like that. He's a good friend to have, you know? I LOVE my turtle friends. They seem like family to me. And Master Splinter - he's like a father to me. Speaking of which, I need to go train with him now. Bye!"

- April


Born on November 28, 1995 to psychologist Kirby O'Neil and the granddaughter of a farmer who discovered a Kraang Scout Ship buried underneath his farmhouse in North Hampton and re-awakened the Kraang inside before they experimented on him, April O'Neil and her father were living in New York City when she met the Ninja Turtles and became the love interest of Donatello. From then on, her life had changed forever and she soon found out that she had inherited a psychic power from her great-grandfather and mother that was the result of the Kraang's experiments on them, making her a target for the Kraang.


April is a teenage girl. Like many of her incarnations, April is a Red-head.(she has black hair in the Mirage comics, and blonde and brown hair in the movies). Her hair is up in a ponytail and she has a yellow headband. She is lean, her height is around Raph's, she has freckles, and blue eyes. She wears brown wristbands, wears a yellow and white shirt with a 5 on it, she has a black t-shirt under it, showing black sleeves, she wears a black choker, jean-shorts with black leggings under them, she has blue and white socks, and black boots. In "Panic in the Sewers", it was revealed she used to wear glasses and once had braces.


Not your typical teenager, April is more comfortable around the Turtles than around her high-school peers. She always knew she wasn't meant to live a normal life, but now that extra-dimensional creatures bent on world domination have kidnapped her super-intelligent scientist father, things will never be “normal” again. She also shows to be stubborn at times such as The Kraang Conspiracy where she constantly insists on coming into TCRI with the turtles even though it's very dangerous and she's not an experienced kunoichi. Like Raphael, she can be very judgmental (for example - while she was trying to discourage Leo fom meeting wih Karai).


April O'Neil may not fit in at school with her peers, but when it comes to the Turtles, she's all about team green! April is the Turtle's link to the "real world" ever since she was thrown into their lives when The Kraang kidnapped her genius father. Clever and independent, this gal's got guts to spare and a mind of mischief. Get ready, Turtles. Splinter is even teaching her the ways of the Ninja.

Abilities and Skills

Ninjutsu: After Splinter began to train her in the ways of Ninjutsu, she became much faster, stealthier, and became a teenage warrior that is fond of self-defense. She does lack offense power, however, which is demonstrated during her first fight with Karai. However, as she continues to train with Splinter her skills and fighting improve.

Telepathy: She has a rare gift that can help her sense certain aspects of other beings, such as psychic abilities. It was this ability that helped her realize that the Monkey shown in "Monkey Brains" was actually a missing scientist. This ability was later used more often and expanded on in Season 2, where it is revealed that she is actually half human and half Kraang. 

Danger Sense: She can sense upcoming danger and read the minds of the Kraang, though the extent of which she can read them is unclear. Also, when in danger and filled with adrenaline, she can emit what is possibly a telekinetic wave that's powerful enough to immobilize every villainous being in TCRI and The Kraang Conspiracy.

Tracking Telepathy: In The Lonely Mutation of Baxter Stockman, she is shown to have some level of tracking telepathy, as she is successfully able to lead the Turtles and Casey to the location of her dad. It seems as though she is capable of tracking any life force within a 2-mile radius.

Tessen: Her Tessen is the weapon that Splinter willingly gave her, which he wanted to give to Karai back when she was his daughter; Though she has yet to fully master using it, she has shown to properly use it in the battlefield on numerous occasions. She seems to be very competent in tossing it at enemies like a boomerang and making sure that it ends up back in her hands.

Mutagen Immunity: Being half-Kraang mutant she is immune to mutagen and her blood is the only ingredient needed to perfect the Mutagen (although the Kraang found another way) and Retro-Mutagen.
