Dawn Harper (Nicky, Ricky, Dicky & Dawn, seasons 3 and 4)

Background
Dawn Abigail Harper is one of the Harper quadruplets and the titular main protagonist of the Nickelodeon series, Nicky, Ricky, Dicky & Dawn. She's the only girl in the quads, leading to circumstances such as fighting with her brothers. She was the first quad born (by 4 seconds), making her the oldest. She believes she's the most mature do to her four-seconds-longer lifespan and the leader quad. She's also somewhat of a lone wolf in the Quad group as she is the only girl and tends to be on her own in fights or arguments with them, being much more independent because of this. Dawn is portrayed by Lizzy Greene.

While she used to be a sort of snarky but mostly kindhearted and funny girl, once season three came around things fell apart.

Why She's Not So Mature Herself

 * 1) She was very badly flanderized in seasons 3 and 4, where she became egotistical, rude, bossy, vengeful, and judgmental, getting worse and worse every episode.
 * 2) She was at her absolute worst in the episodes Ye Olde Hand Holde and Tween Wolf, being irritatingly sexist and arrogant.
 * 3) She tends to not care about anything that happens to anyone around her until it starts negatively affecting her as well. To be fair, while her brothers can act the same way, she does this a lot more frequently.
 * 4) She gets mad at her brothers when they do things that were clearly accidents, and sometimes they were even trying to help her succeed in things.
 * 5) She always assumes she's the leader of her siblings. In fact, she once had flashback to inside her mother's womb somehow, where she imagined herself as the leader, and in her flashback she even imagined Ricky saying he wasn't smart, implying she thinks he's dumb. Now, while siblings say things like this to each other from time to time, Dawn actually believes it as a fact.
 * 6) One time, she abandoned her brothers and actually said she would rather be in another family. Now, while she was very angry, that's still an really mean thing to say to your own brothers.
 * 7) When she wasn't invited to hang out with a girl named Simone, she was completely in denial, and even though it was supposed to be a joke, it was flat out not funny at all.
 * 8) She never does the right thing when she and her brothers are in a sticky situation, always wanting to take the "easy" way out. One time she even slapped her brothers when they wanted to do the right thing.

Redeeming Qualities

 * 1) She has a few funny moments here and there.
 * 2) She has shown a few times that she genuinely cares about her brothers, although those are very few and far between.
 * 3) She is usually a pretty good friend to Mae.
 * 4) In the end, she usually makes up with the people she wronged.
 * 5) She's often the one who knocks some sense into her brothers when they freak out.
 * 6) With the exception of one episode, she is usually supportive of Mae and Miles' relationship.
 * 7) Nicky, Ricky, Dicky, and Dawn would not be the same without her.
