Main characters


Contrary to popular belief, Arnold does not wear a kilt, but instead dons a plaid shirt that hangs out of his blue sweater and a hat that only covers a small part of his football-shaped head.

Arnold (voiced by Toran Caudell in seasons 1–2; Phillip Van Dyke in seasons 2–3; Spencer Klein in seasons 4–5; Alex D. Linz in season 5) is the nine-year-old protagonist and title character of the series. He is a dreamer and an idealist who always tries to see the best in people and do the right thing. Whenever he sees someone in trouble, especially Helga, Arnold goes out of his way to help them out, even if it is not sensible to do so. Arnold often acts as the stable center to those around him, whether he is around his "family" in his paternal grandparents' boarding house, or around his friends at school. He lives in Sunset Arms boarding house with his grandparents, Phil and Getrude.[1]

Arnold has had two major crushes in the series: one with sixth-grader Ruth McDougal (through most of season 1), and one with a classmate named Lila Sawyer (introduced in season 2). However, his most catalytic relationship is with his classmate Helga Pataki. Helga is secretly in love with him, though to keep these feelings secret she bullies Arnold. Arnold seems unaware of this fact for most of the series, other than the occasional hint from Helga and other classmates. Helga's secret was revealed to Arnold during the Hey Arnold! movie, but Arnold gave Helga the opportunity to refute her confession, attributing it to "the heat of the moment".[2] According to series creator Craig Bartlett, had the canceled "Jungle Movie" sequel been animated, Arnold would have returned Helga's feelings with a kiss of his own, with his best friend interrupting the moment. Arnold is friends with most of his fellow fourth-graders, with the best of which being Gerald Johanssen, whose friendship dates as far back as preschool.[3]

Arnold's surname is never revealed on the show and the mystery surrounding his full name became a running gag on the show, by the last name almost being revealed, then someone or something interrupting or otherwise preventing it from being heard.[4][5][6]

Arnold was voiced by Toran Caudell in season one and six episodes in season two. Phillip Van Dyke took over the role for the remainder of season two and all of season three, followed by Spencer Klein in seasons four and most of five, and Alex D. Linz in the fifth season episodes "April Fool's Day" and "The Journal".


Gerald Martin Johanssen (voiced by Jamil Walker Smith) is a nine-year-old boy and Arnold's best friend. He is an athletic and street-smart boy who is portrayed as loyal, though much less responsible than Arnold. Gerald has known Arnold for many years. Besides being Arnold's friend, Gerald also has a good deal of knowledge of many legendary stories in the city, or "urban legends" as he calls them. He apparently gets these myths from a source he has nicknamed "Fuzzy Slippers", mentioned in many episodes as his reliable assistant.

At school, Gerald is the class president, and considers himself very cool, and apparently, so do his friends. When it was revealed that Arnold was on Rhonda's so-called "Cool List", and that Gerald was on her other list known as "The Geek List" (due to a grudge Rhonda had against him over running for class president), many classmates were surprised to find this out ("Cool Party").

His most distinct features are his tall, Kid 'n Play-style hair, and his shirt with the number 33 on it (he also wears 33 on sports uniforms). He has a crush on Phoebe, who shares the same feelings for him.


Helga Pataki, in her signature pink and red dress and pink bow

Helga G. Pataki (voiced by Francesca Smith) is an insecure and cynical girl who puts on a mean, tomboyish front, making her the school bully.[3] She constantly bullies Arnold to hide her true feelings of love for him, which is obsessive to the point where she has made many shrines dedicated to him. She is an extremely gifted student and a talented writer for her age. She occasionally expresses interest in pursuing the latter as a career. Despite this, she is neglected by her parents[3] and often calls them by their first names because she does not think they are worthy of being called "Mom" and "Dad". Her alcoholic mother, Miriam, is usually depressed, forgetful, struggling to stay conscious, and frequently drinking "smoothies" and "coffee." Helga relates very poorly to her. Her father, Bob, a successful pager salesman who suffers from workaholism, rarely notices her existence, favoring her over-achieving, neurotic college-aged sister Olga, who Helga rarely gets along with. Helga does not really see him as her father as he is a horrible one. He never listens to Helga and sometimes hits her. Helga is also known for her catchword, "criminy", which she normally exclaims when stressed.

Helga resents her older sister, Olga.[7] Once in a while Helga will show a very small amount of love for her sister, as in the episode "Olga Gets Engaged", when she intervenes on Olga's behalf, saving her from what would have been a bad marriage,[8] and "Big Sis" when she reveals her jealousy of Olga's relationship with Lila.[9]

Supporting characters

  • Phoebe Heyerdahl (voiced by Anndi McAfee) – The smartest girl in the class. She is Helga's best friend and confidante, though Helga tends to boss her around.[10] Her ethnicity is half-Japanese, but she is from Kentucky. Throughout the series, both she and Gerald have a love interest in one another.
  • Harold Berman (voiced by Justin Shenkarow) – A Jewish American school bully and friend of Arnold.[11] He is 13 years old and overweight and in later episodes it is revealed that Harold has a soft spot.[12] Despite his teasing and bullying tendencies, Harold is often revealed to be rather cowardly and usually cries for his mother whenever he gets scared or upset.[13][14] He is sometimes referred to by the derisive nickname "fat boy."[15] His best friends are Sid and Stinky.
  • Stinky Peterson (voiced by Christopher Walberg) – Stinky is a tall and lanky friend of Arnold's from Arkansas, and he is also one of Harold's best friends. Stinky has a southern accent and a love for lemon pudding. His friendship with Harold had him originally portrayed in the first season as a bully and sidekick of Harold's who wore spiked wristbands, though the former was later de-emphasized and he was reinvented as a more affectionate, mild mannered and romantic character viewed as the class "ladies man", as he is romantically attracted to several female characters. He is shown to make up excellent poems while Phoebe is feeling depressed.[14]
  • Sid (voiced by Sam Gifaldi) – A friend of Arnold and one of Harold's best friends with paranoid tendencies. He is always shown wearing a green baseball cap backwards, a black leather jacket, and white Beatle boots. He often tells urban legends, with or without the assistance of Gerald. Perhaps his most well-known characteristic is that he typically ends up in ridiculous situations, such as becoming severely mysophobic; deciding to devote his life to Arnold after Arnold saves his life, among other things.[16][17]
  • Grandpa Phil (voiced by Dan Castellaneta) – Arnold's cheery, fun-loving grandfather. He is 81 years old, as of the episode "Grandpa's Birthday".[18] Arnold often comes to him for advice.[19] He often tells Arnold stories about his past experiences, although he has a tendency to stretch the truth. Despite responding frivolously to Arnold's problems, he will often provide good wisdom. He is a World War II veteran and claims to have single-handedly won the Battle of the Bulge by tricking a large troupe of Nazi soldiers into eating numerous cans of spoiled CHAM, thereby poisoning them and creating a hole in the enemy line for the American troops to break through. Arnold does not believe his story at first, but it is later proven when Phil shows him a small monument of him hidden in some bushes in a park in Washington D.C.[20] Phil was also a master at Chinese checkers in his youth, which earned him the nickname "Steely Phil".[21] He is very healthy for his age, as well as athletic.[18]
  • Grandma Gertrude (voiced by Tress MacNeille) – Arnold's wacky but wise grandma who is often seen doing outlandish things, including dressing up and acting like fictional and historic figures, such as Calamity Jane.[18] She is called "Pookie" by Grandpa Phil.[18] She has a black belt.[22] She and Phil had a similar relationship that Helga and Arnold have when they were kids (though her antics were a bit more vicious and extreme).[23]
  • Rhonda Wellington Lloyd (voiced by Olivia Hack) – A rich, pompous, self-proclaimed fashion queen and friend of Arnold. She is one of the most popular students attending P.S. 118. Both of her parents are stereotypically preppy.
  • Eugene Horowitz (voiced by Christopher Castile for eight episodes, then Jarrett Lennon, then Benjamin Diskin in 1997–2000) – A somewhat socially inept but optimistic friend of Arnold, the class jinx. Eugene is prone to several forms of misfortune and is often bullied. He believes Arnold is a jinx due to several of his past tragedies having occurred in Arnold's presence.[24]
  • Lila Sawyer (voiced by Ashley Buccille) – A nice girl who came from a fictional farming community she calls "Pleasantville" and who lives with her father.[25] Her mother is never seen or mentioned. She is Arnold's crush. However, she only prefers Arnold as a friend. She had a crush on Arnold's cousin Arnie. She knows that Helga loves Arnold[26] and offered to help Helga become more like her in one episode. She is described by the show's creator as being a foil for Helga and as having a sort of twisted darkness hidden beneath her kind exterior.
  • Robert "Big Bob" Pataki (voiced by Maurice LaMarche) – Olga and Helga's oafish, ambitious entrepreneur father, a successful beeper salesman who owns a beeper store.[27] He has extremely high expectations for Helga and frequently compares her to her older sister Olga. Bob also frequently calls Helga by Olga's name by mistake.[3][28] However, Bob does care for Helga as is evidenced in subtle ways.[28] Bob has difficulty showing his emotions for Helga since she and he always come into conflict with each other. He often mistakenly calls Arnold "Alfred".[29]
  • Miriam Pataki (voiced by [8] She reveals in the episode "Olga Gets Engaged" that she regrets marrying Bob.[8] and she used to be an Olympic class swimmer.[32] However, her sobriety doesn't last long because in episodes following this one, she is back to drinking smoothies. Miriam was a champion bull rider before marrying Bob,[30] and realizes that she is ignoring Helga. Then, she quits and makes Bob return to work.workaholic as a plot point. However, in one episode when Bob injures his back and can't work, Miriam fills in for him. During the episode Miriam sobers up and holds the fort. Miriam also becomes more attentive towards Helga until she becomes a Alcoholics Anonymous, would have included her struggle with alcoholism and joining of The Patakis spin-off, Hey Arnold! The unaired [32][31][30]
  • Olga Pataki (voiced by Nika Futterman) – Helga's intelligent, outgoing, beautiful older sister, who attends Wellington College (fictional, as Wellington College, UK, is actually a secondary school).[7] But in one of the episodes, Helga says that Olga attends Bennington College, which is an existing college located in the U.S. state of Vermont.[3] Olga clearly suffers from perfectionism. She attended P.S. 118 as a child, and is praised by Helga's current teachers for her achievement. Bob and Miriam consider Olga to be perfect, which bothers Helga.[7] There are times where her parents will confuse Helga for Olga.[3][28] Fortunately, Olga does give Helga more attention than their parents much of the time and has good intentions. However, Helga does not receive Olga's attention or intentions very well and often tries to push Olga away and keep her distance. Olga has a tendency to view life through rose colored glasses and appears not to notice Helga's avoidance tactics. Therefore, either Olga likes to avoid conflict since she rarely acknowledges her family's problems, is oblivious, or is in denial. It is revealed in the episode "Helga on the Couch" that Olga through the years has reacted to her family's problems by being a perfectionist and keeping quiet about the situations at hand.[3] She later reveals to Helga that she is envious of her, as unlike Olga, their parents never heaped unrealistic expectations onto her, comparing herself to a "wind-up toy" that performs for their parents.

They returned to the city after Arnold's birth, but were called back for 'a final mission' when a friend informed them that the Green Eyes were in trouble: they failed to return, leaving their son presumably orphaned.

Apparently Brainy has not told anybody else about Helga's crush on Arnold.

  • Ludwig (voiced by Phillip Van Dyke) – A bully who was Wolfgang's rival and is later Wolfgang's friend.[59] His name is likely a reference to Ludwig Van Beethoven, a famous classical composer, as a counterpoint to Wolfgang who shares his first name with classical composer Wolfgang Amadeus Mozart.
