April O'Neil (2012 TV series)

April O'Neil is an ally to the Teenage Mutant Ninja Turtles.

History
April met the Turtles when she and her father (Kirby O'Neil) were attacked by the Kraang. She was afraid of the mutants at first, but started to trust them thanks to Donatello. They group was unable to fight effectively as a team, however, and the Kraang succeeded in kidnapping April and her father. While she was trapped in their hideout, April tried to trick the Kraang into letting her escape, but her plan failed. Later the Turtles came to her rescue. Eventually they succeeded in saving April, but the Kraang got away with her father. Later the Turtles met April at her aunt's apartment, where she would now be staying. April was safe, but upset over the loss of her father and determined to find him. The Turtles promised to help her get him back.

Since then April has become good friends with the Turtles and cooperated with the them on various missions. In Turtle Temper she gave them information about the Kraang's plans to break into a lab. In New Friend, Old Enemy she showed Michelangelo how to use the Internet to make friends online. In Metalhead, she played a very active role by infiltrating a Kraang hideout and learning their plans to put mutagen in the city's water supply. She was also able to defeat one of their guards on her own and escape to inform the Turtles of the enemy plans.

As of Monkey Brains, April has begun training with Splinter in the ways of the ninja. While she is not on the level of the Turtles in terms of fighting skills, she has shown improvement in matters of stealth and spying.

Personality
April is a smart, strange sixteen year-old girl with an indie rock vibe. The fact that April feels more comfortable with four mutant reptiles than with her high-school peers should tell you a lot. She is also feisty, determined and resourceful. She is also fiercely loyal to her mutant friends, as seen in Panic in the Sewers. When the turtles were ready to give up, April volunteered to find out Shredder's plot.

Relationships
While she is friends with all the Turtles, April seems to have the closest friendship with Donatello. He has a crush on her, and while she doesn't seem to notice it, Donnie's brothers do and enjoy teasing him about it.

While April's relationship with her father has not yet been explored very deeply, her determination to rescue him shows that she cares for him very much. Her only other known relative is her aunt, whom she is currently living with.

It's possible that she may start dating Casey Jones once he's official introduced into the series.

Even though her main friends are mutant turtles, she does have some human friends. One of them is Irma. Not much is known about her yet, but we know that she has at least one human friend.

Appearance
April appears as a young-looking 16 year old. She has orange hair that appears to be tied up on a small ponytail and curved bangs that go to the right. She also has a yellow headband. April wears a elbow-length black shirt with a yellow and white sport shirt with the number "5" over it, blue denim shorts, black leggings, brown bandages/bracelets arond her wrists, white high socks with two blue tripes on them, and black low-heeled boots. Though you may not notice it, April has a clip on her right back pocket of her shorts. The clip is colored gold and has a little ball with a heart. There also appears to be keys that we are guessing to be house keys. April is very slim and has blue eyes with one eyelash. Donnie finds all of these features "attractive", leading to his crush on her.

Trivia

 * April is now 16 years old. The reason for this is that Nickelodeon thought it would be odd for an adult woman to be hanging out with teenagers (the Turtles).
 * The number five on April's shirt may be a reference to her role as "The Fifth Turtle".
 * April is currently living in the same building as an antique store called "Second Time About". This is likely a reference to some of her previous incarnations working in an antique store with a similar name, "Second Time Around".
 * So far April has appeared in every episode of the new series except for three: "Turtle Temper", "I Think His Name is Baxter Stockman", and "It Came From The Depths".
