Sydney Sellers is a 15-year-old girl. She has long, chestnut-brown hair and green eyes. Sydney is good-natured and sociable... perhaps too sociable. She always wants to meet new people and tries almost too hard to become friends with them. She enjoys cosplaying, and will always seize an opportunity to dress up in an outlandish costume, whether based on pre-established characters or ones of her own creation. She loves to write stories, particularly in the realm of fantasy, and they always seem to be outlandish and out of control. Sydney is friendly most of the time, a tad socially clueless, and can talk a person's ear off if they let her. All she wants to do in her high school years is make friends and leave her mark. She is easy to befriend, although she is almost always beside her best friend, Alyssa, and her other friends, Ryan and Austin.

Regarding Austin, while the two are friends and will help one another when they need it, they almost always engage in debates and rivalries. Way more than good friends should. Their ideals and beliefs differ vastly from each other, often leading to disagreements of such intensity, that you could swear they would engage in a fistfight. 

Her voice is in the high vocal range. Particularly low or directly in the high range. Her voice sounds youthful and full of energy. She expresses a wide variety of emotions, from extreme happiness to bitter sadness. Her lines involve screaming and yelling, in both positive and negative cases. A few of her lines are long because of her talkative nature and how easily she can release a constant stream of chatter. The voice should sound friendly and energetic, one full of life and vibrancy.
