Nicole "Nikki" Julliane Maxwell is the protagonist and narrator of Dork Diaries series. She is Brianna Maxwell's older sister. She labels herself as a "dork" and goes to Westchester Country Day on a scholarship, because her father is the school's exterminator. One of her biggest fears is that someone will find out that she attends Westchester Country Day on her dad's bug extermination scholarship. Nikki's best friends at school are Chloe Garcia and Zoey Franklin and is the love interest of Brandon Roberts. Her enemies are Mackenzie Hollister and Jessica Hunter.
She is just an Bloo wannabe: acts like a villain instead of a hero and only cares about herself-herself, her diary, and her dorkiness and thinks she is better than anyone else when she's not.
She is very ungrateful and disrespectful towards her parents; she calls them "brain dead" just because they don't want to buy her a new phone and her dad is an exterminator.
She also bullies her younger sister Brianna just because she is not as "perfect" as her, calls her a brat (when she’s just a cheerful little girl) and even wishes her to be dead!
Sometimes she only cares about what she looks like or how popular she is. All she ever thinks about is being better than anyone else or being someone she is not. All the problems she has either revolve around being "single" or stereotypical "girly girl" problems like not having nice enough clothes, or dealing with mean girls like Mackenzie.
She overuses￼ certain words like "OMG", "dork" and "SQUEE" which can get really annoying to the extent.
She wastes her time drooling and obsessing over her crush Brandon, which gets extremely weird and disturbing.
She gets little-to-no character development and characterization throughout the series as she remains the same.
She acts like her life is a great big problem and doesn't appreciate the love her family give her.
There are kids out there with no food, water, parents, education, who are abused to the point of suicide, who are poor, who wear old outgrown clothes, who are homeless, etc. Yes, she may be bullied by MacKenzie, but she has friends who care for her, loving parents, a loving sister, food on the table, nice clothes, and a roof over her head.
Her personality is way too similar to Greg Heffley from Diary of a Wimpy Kid. However, she isn't like him trying to gain clout by doing things that are stupid like breaking Rowley's arm for instance and trying to get anyone's attention to it.
In some of the comic strips located at the back of the cover, She's being rude to MacKenzie even though MacKenzie didn't do much of anything to her.
Her anime-esque character design is somewhat pretty.
She still loves her family and friends despite her selfish attitude.
There are times when Nikki is nice and supportive towards her friends and family.
Nikki is a pretty good artist compared to MacKenzie in Tales from a NOT-SO-Dorky Dream Queen.
She is right about Brianna being a pest sometimes, though this is because she is little.
Sometimes, she stands up for herself when MacKenzie does something cruel to her.
Compared to other characters, she actually cares the most about her schoolwork.
