Helga Pataki

Helga could be classified as a tomboy, as evidenced by her interest in playing contact sports alongside her male classmates and disregard/dislike for stereotypical female behavior, although this is countered by her fondness of the color pink and otherwise girly clothing choices. She can also be cynical, deceitful, violent, tough and bossy, bullying her classmates with an iron fist, and often taking advantage of her best friend, Phoebe, making her a bit of a selfish brat. She also tends to reply sarcastically to express her annoyance and usually mocks her classmates by calling them nicknames.

However, Helga also has a much softer side, which becomes apparent when she is alone and involved in her schoolwork. She is very emotional, poetic, sometimes caring, and as such, able to comprehend a spectrum of emotions such as love, passion, ambition, affection, concern and care on the one hand and hate, jealousy, frustration, annoyance and spite on the other. She was also portrayed as a villain on occasions while in some of the series. This emotional extremity is a running joke throughout the series.

Although Helga is seen as a "tough girl" by her classmates, she is frequently the first to go into hysterics in times of crisis. Harold is similar to Helga in this regard.

She has also been known to be somewhat materialistic.

Appearance: Helga is an 18 year old girl with long blonde hair like her mother, her fathers unibrow, nose and ears. She wears pink clothes, mostly either a pink shirt, hoodie, sweater, t shirt, tank top, pants, etc. With jeans either ripped or shortened, as well as white shoes. And occasionally wears her large pink bow she's always had since she was younger.

Hillwood is the city where Arnold lives, and where most events of the show ("Hey Arnold!") take place. It is located in Washington state, as revealed and evidenced throughout other the show in many episodes. The city's name is never said aloud in the series, though it can be seen written in several locales throughout various episodes.

Real-life inspirations Washington State "Welcome to Washington State" sign, at the end of the episode "Road Trip". This adds credence to the notion that Hillwood is located in the state of Washington.

According to an interview with Craig Bartlett, Hillwood is an amalgam of large Northern cities in the United States, including Seattle, Washington (his hometown), Portland, Oregon (where he went to art school), and Brooklyn, New York City, New York (the bridge, the brownstones, and the subway). New York City was also seen in two episodes of the show ("Married" in Helga's dream and "Rich Guy" in a photograph), presumably as a separate city from Hillwood in-universe..
