Katelyn (MyStreet)

Early Life
In "The Decoration Fight," she is revealed to have brothers and came from a poverty-stricken home.

MyStreet Phoenix Drop High
In her sophomore year, she struck Travis with a volleball, leaving the him unconscious.

Katelyn and Jeffory are in an a relationship. The two get along fairly well. Jeffory often annoy Katelyn, but she does not appear to be bothered by it and simply goes along with it.

During final exams, she and Jeffory broke-up for unknown reasons. Later, she and Jeffory agreed to continue as friends.

MyStreet
In MyStreet, she moves into new house with Aphmau and Kawaii~Chan. With the revelation of the guys moving in across from them, she likes to torment Aphmau on the guys whose fallen in love with her. She is seen to have a more agressive side as she was willing to attack Aphmau during their snowball fight, overall she has a short fuse that can explode at any given moment. Katelyn despises Kawaii~Chan's obsession with shipping, and scolds her for it greatly. Although Katelyn is short-tempered and sarcastic, she is apologetic to those she hurt accidentaly.

She finds it hard to apologize for her wrong doings and would rather put behind her. Katelyn is shown to have interest in plays and creative arts in general. During the neighborhood play story arc, she shows Jeffory that she wanted to attend a few college courses and direct plays. Once Jeffory informed Aphmau about their current situation, Katelyn was overjoyed to hear that Aphmau and Zane were producing a play. Rigorously, she wanted the play to go on smoothly, writing the play immediately and accepting the job as a director. After the play had completed, she is delighted at the great response, and plans to create more plays.

Minigames
Katelyn reveals to Aphmau that she is dating Jeffory. Their relationship appears to have been kept a secret for the fact, Katelyn doesn't want her Dad (Eric) to find out.

Appearance
Katelyn has pale skin, sky blue eyes, and pastel blue hair that partially drapes over her right shoulder.

In a lot of her outfits, Katelyn incorporates the colour blue, which appears to be her favourite colour, though she seems to also like the colour white, beige and grey in her outfits, as they are also recurring colours.

Personality
In MyStreet, Katelyn keeps her serious and quiet nature. Although she can get angry at times, she easily mellows her nerves by meditating. She also mocks of others misfortune and mock them in a playful manner. However, if her intentions do hurt people she care about, she will likely keep to herself, isolating her from the problem and would rather forget. Katelyn does possess a stressful nature during moments of hysteria as she can be so distraught that her thoughts may not be clear and become to gullible at any suggestion given.

Her kind nature is expressed by her closed friends, such as Aphmau, Nicole, Kawaii~Chan, Jeffory, and Abby (Jeffory's daughter). Katelyn seems to be fond of Abby as the two are seen to be very close. Abby seems to have taken a liking of Katelyn's mannerism and fighter attitude. She takes her school work seriously, even if it makes her anxious and hysterical. She holds a competitive nature, where she often compete against her friends.

Interests
Katelyn has an evident passion for the theatre, though she tends to be quite secretive and embarrassed by it, and appears to be fan of the play Romeo and Juliet by William Shakespeare, having always wanted to direct it in the theatre. It is also possible that she had read other Shakespearean works, though she has not mentioned it. She has also expressed an interest in singing and screenwriting. Katelyn is also quite athletic, and was the captain of her high school's volleyball team.

She likes One Direction, but is very embarrassed by it and so like to keep her poster of them hidden in the back of her closet. If the posters on her bedroom wall are anything to go by, she is also a fan of the American rock band Linkin Park, and a fan of the television series Once Upon A Time. It also seems that she is a fan of cartoons, since during A-Con 2016 she attends the convention cosplaying as the characters Ruby from Steven Universe and Fiona from Adventure Time. However, she is also very shy about this as well, and she behaves very indifferent about attending the convention until Aphmau tells her that she can do whatever she wants, at which point she runs off into the midst of the convention while giggling and squealing in excitement.
