Characters

The Stortmans

• Arnold Phillip Shortman (voiced by Toran Caudell in season 1 and two episodes in season 2, Phillip Van Dyke in seasons 2 and 3, Spencer Klein in seasons 4 and 5, and Alex D. Linz in two episodes in season 5) - The main protagonist and title character of the series. 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 tends to day dream from time to time. He lives in a boarding house with his grandparents. His last name was revealed to be "Shortman," a name that his grandpa frequently calls him throughout the series. The fate of his parents remains a mystery. He is often seen as the voice of reason in any dispute that comes up, whether it involve his friends or the boarders.

• Grandpa "Steely" Phil Shortman (voiced by Dan Castellaneta) - Arnold's fun-loving, wise-cracking grandfather. He is 81 years-old, as of the episode "Grandpa's Birthday". Arnold often comes to him for advice, to where he often tells Arnold stories about his past experiences, although he's had the tendency to stretch the truth. He is a World War II veteran, in which he 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 didn't believe his story at first, but it was later proven when Phil showed him a small monument of him hidden in some bushes in a park in Washington D.C. Phil was also a master at Chinese checkers, which earned him the nickname "Steely Phil". He is very athletic and can bench press up to 210 pounds.

• Grandma Gertie Shortman (voiced by Tress MacNeille) - Arnold's wacky but wise grandma who is often seen doing outlandish things. She is called "Pookie" by Grandpa Phil. She has a black belt. She and Phil had a similar relationship that Helga and Arnold have when they were kids (though her antics were a bit more vicious).

• Arnie - Arnold's strange look-alike cousin who lives in the countryside. He likes to collect lint, count things, and read the ingredients on the back of food containers. He is Lila's crush, but he loves Helga. He is often seen as strange, gross, dull or stupid by those around him.
• Miles Shortman - Arnold's father.
• Stella Shortman - Arnold's mother.
• Aunt Mitzi (voiced by Phyllis Diller) - Arnold's great aunt, Phil's twin sister and childhood rival.
• Grandpa's father - He often seen in Grandpa's flashbacks to the 1920s.
• Grandpa's grandfather - He was seen in another one of Grandpa's flashbacks. He remembered doing chores one winter while his friends were ice skating only to be hit with a snowball by his grandfather who gave him permission to stop his chores and play.

The Sunset Arms boarders and their families

• Oskar Kokoshka (voiced by Steve Viksten) - A lazy, self-centered con artist, presumably an immigrant from an Eastern European country (in one episode he is referred to as being Czechoslovakian), that remains unemployed through most of the series until becoming a paperboy. He is hated by pretty much everybody in the boarding house, especially Ernie Potts. His voice resembles that of comedian Yakov Smirnoff and he occasionally utters Smirnoff's catchphrases such as "What a country!" He shares his name with an Austrian artist.

• Suzie Kokoshka (voiced by Mary Scheer) - Oskar's caring wife, who puts up with all of her husband's antics and laziness.
  • Nancy and Baby Oskar - Suzie's sister and nephew (Nancy never resided in Sunset Arms). They lamented that they named the baby Oskar before knowing Suzie's husband, Oskar's actual character.

• Ernie Potts (voiced by [[Dom Irrera) - A short-statured and hot-headed demolitionist who has a Napoleon complex.

• Mr. Hyunh (voiced by Baoan Coleman) - He is last name is pronounced "win." He is an immigrant from Vietnam, working in a Mexican restaurant. Despite having a heavy Vietnamese accent when speaking, it is revealed that he is very talented in singing country music with the singing voice provided by country singer, Randy Travis.
  • Mai Hyunh, Mr. Hyunh's long lost daughter (never resided in Sunset Arms). She only appeared in the Christmas episode. It was revealed in the episode that she had been given to American troops during Fall of Saigon.

• Mr. Smith - A mysterious person who is extremely secretive (to the point of communicating only through security cameras) and never speaks or shows himself to the rest of the boarders (appears in the first season only). His two floor apartment is said to have it's own shower and a two-way high-tech dumbwaiter which carries his meals. Outside of the door to his apartment is a keyboard where different codes are entered in order to either access the rent money safe or drop of one of Mr. Smith's dry-cleaned suits on a rack. Whenever Mr. Smith leaves the boarding house, he is only seen in a bowler hat and trenchcoat that hides his face.

• Lana Vail - She only appeared in the first season only; but seen as an extra in later seasons.

• Mr. Purdy (voiced by Joseph Purdy) - He only appeared in the first season only.

Arnold's classmates and their families

• Helga Geraldine Pataki (voiced by [[Francesca Smith) - Helgais nine years old and in fourth grade. She is secretly in love with her classmate Arnold because he's the first person to give her attention and be nice to her. In one episode, Helga revealed to Lila that she loves Arnold so that she could get the role of Juliet in the school play and kiss Arnold. Later in the series, Helga admits to being in love with Arnold to the school psychologist, Dr. Bliss. However, it is implied that her best friend Phoebe is aware or suspects that Helga loves Arnold as in when she uses the code word "ice cream" during conversations. During her spare time she likes to devote her time to writing poems (mostly about Arnold) and collecting Arnold's used gum so that she can add it to her shrine of him which is a work in progress. She is neglected by her parents and calls them by their first names because she doesn't think they're worthy of being called "mom" and "dad." On rare occasions she does call them mom or dad. She resents her overachieving, perfectionistic older sister, Olga. 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 and "Big Sis" when she reveals her jealousy of Olga's relationship with Lila. Probably because of her dysfunctional homelife, Helga is an insecure person and puts on a mean, and/or tomboyish front, making her the school bully.
  • Robert "Big Bob" Pataki (voiced by Maurice LaMarche) - Helga's ambitious entrepreneur father, a successful beeper salesman who owns a beeper store. He has extremely high expectations for Helga and frequently compares her to her older sister Olga. However, Bob does care for Helga and it is evidenced in subtle ways. In the Halloween episode when Helga and her classmates dress up as aliens and things take a turn for the worse when the people in there city think they're real aliens, Helga's friends run to the water tower that they made to look like a UFO. Meanwhile Bob and his friends go to the water tower and throw a grenade at the water tower thinking it's a UFO. Bob sees the "aliens" and gets a hold of Helga unbeknownst to him and shakes her. All the while she keeps saying "Dad! It's me, Helga!" Once the water leaks from the explosion and rinses away the facial paint, Bob realizes it really was Helga and not some alien trying to play a mind game. He says "I almost hurt my own kid! I'm a monster!" And gives her a hug as well as a piggy back ride down the hill. The episode where it is very evident that Bob does care for Helga is near the end of the episode "Quantity Time." Bob has difficulty showing his emotions for Helga since she and he always come into conflict with each other and clash. He often mistakenly calls Arnold "Alfred".
  • Miriam Pataki (voiced by Kath Soucie) - Helga's inattentive mother. There are implications that Miriam suffers from alcoholism, as she often drinks "smoothies", forgets things, speaks in a slow, tired voice, has had her driver's license revoked, has to do community service and sleeps a lot (often in inappropriate places). 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. She also becomes more attentive towards Helga until she gets carried away with the job and realizes that she is ignoring Helga. Then, she quits and makes Bob return to work. However, her sobriety doesn't last long because in episodes following this one, she is back to drinking smoothies. But the viewer learns in a Mother's Day episode that Miriam was a champion bull rider and an olympic swimmer before marrying Bob.
  • Olga Pataki (voiced by Nika Futterman) - Helga's intelligent, outgoing, beautiful sister, who attends the fictional Wellington College (or in another episode, Bennington College) and suffers from perfectionism. Bob and Miriam consider Olga to be perfect, which bothers Helga. There are times where her parents will confuse Helga for Olga. 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 nor does she react to Helga's short temper when it is directed towards her. Therefore, either Olga likes to avoid conflict since she rarely acknowledges her family's problems, is oblivious, or 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. This is evidenced in a flashback when Helga, as a toddler, interrupts Olga who is playing a tune on the grand piano. She tries to remind her parents that she has to go to preschool but is told by Bob, "Not now! Why don't you go play or something." However, she is ignored entirely by Miriam and Olga during the whole scene as well as by Bob after he blew her off. But after Olga completes the tune, she is too busy basking in her parents' attention. Whether she ignores Helga in that scene because she is being selfish and not wanting Helga to take away the spotlight or just oblivious is not established. But the viewer does learn from the flashback that the neglect that Helga has endured has been ongoing for years. Due to the names "Olga" and "Helga", it can be presumed that they are of Russian/Germanic descent. Also, both names have the same meaning and are variants of each other. In addition, "Pataki" is a traditionally Hungarian surname. Also Helga, Olga and Robert are common Hungarian first names, however Miriam, while is an existing Hungarian female name, is very rarely given to baby girls.

• Gerald Johanssen (voiced by Jamil Walker Smith) - Arnold's best friend, who is African American. He is the keeper of several of the town's urban legends. Throughout the series both he and Phoebe, another classmate, have a love interest in one another. He is also known for his funny looking afro, similar to Marge Simpson's.
  • Martin Johanssen (voiced by Rick Fitts) - Gerald's father who is a businessman. He is obsessed with saving money, often going over the top on the price of things like the Electric Bill. It is revealed he is a Vietnam veteran, and earned Gerald's respect when Gerald finds out his father, a messenger and staff officer, saved the life of a downed Helicopter pilot.
