 * Characterization Marches On: He was more eccentric and naive early on.
 * Chick Magnet
 * Cloudcuckoolander: In the early seasons, anyway.
 * Determinator: When he's on a mission, don't except to give easily until he review all options... and rarely does he run out of them.
 * He mostly would stand up for others who are looked down upon and prove one's innocence like he did for Eugene in "False Alarm".

 * Abusive Parents
 * Beneath the Mask: She pretends to hate Arnold to hide her true feelings for him, and only expresses said feelings when she's alone. Or she thinks so, and Brainy teleports behind her.
 * Cannot Spit It Out: And when she did it in The Movie... she took the chance Arnold give her to deny it.

 * In "Curly's Girl", Helga calls Rhonda for dumping and embarrassing Curly after pretending to be his girlfriend.

"Helga: "Why are none of my evil schemes working?!""
 * Evil Laugh: Has a very impressive one. Not as impressive as Curly's (but then, who could be), but she gets points for once doing it in a theatre, with ominous music and everything.

Rhonda Wellington Lloyd

One of the most popular kids in school and self-proclaimed "fashion queen", Rhonda is spoiled, rich, obsessed with fashion, and is a bit of a snob, but she does have a friendly side that comes out quite often. Her best friend is Nadine, but she's often seen hanging out with Arnold and the gang. It's implied that she and Harold like each other, and Curly likes her too... much to her chagrin. She's also a surprisingly good football player.


 * Alpha Bitch: Very often.
 * Break the Haughty: All the freaking time, but most notably Rhonda's Glasses and Rhonda Goes Broke.
 * Fallen Princess: This is the subject of a couple episodes (most notably "Rhonda's Glasses" and "Rhonda Goes Broke"), but she's always back on top by the end.
 * Heroic BSOD: When her family goes poor in "Rhonda Goes Broke" - specifically, when everybody finds out that she's poor - Rhonda has a major one, spending all her time in her room miserably crying. Luckily, Arnold reboots her when he talks some sense into her and asks if being rich is all she's about.
 * Jerk with a Heart of Gold: She does have a good heart under her vain, self-centered exterior.
 * Large Ham: She's pretty prone to this when she breaks into histrionics, especially in the episode "Rhonda Goes Broke".

 * Rich Bitch: On her worst days.
 * Shiny Midnight Black
 * Tomboy and Girly Girl: Girly Girl to Nadine's Tomboy.

"Voiced by: Justin Shenkarow"

A fat kid who's been held back a few grades. Occasionally, a bully.


 * Big Eater

 * Jerk with a Heart of Gold
 * No Indoor Voice
 * Only Known by Their Nickname: His given Hebrew name is Chaim, But he preffers to be called Harold.

Sid
"Voiced by: Sam Gifaldi; Taylor Gifaldi ("April Fool's Day")"

A paranoid boy in a hat.

 * Gag Nose
 * Trademark Favorite Food: Lemon pudding

Lila Sawyer
"Voiced by: Ashley Buccille"

A poor country girl who transfers to the school.


 * The Chick
 * Country Mouse
 * Foil: To Helga, big time. A great deal of Lila's appearances, and the nature of Arnold's relationship with both, play up how Lila is everything Helga isn't.
 * Not only that, but according to Craig, Lila had a repressed dark side. So, while Lila was sweet and innocent on the outside, but emotionally disturbed on the inside, Helga was mean and crazy on the outside, but kind and sophisticated on the inside.
 * Heroes Want Redheads
 * Not So Above It All: Not shown too much in the series, but in an interview Craig Bartlett said she had a hidden dark side.

 * Ax Crazy
 * Creepy Child
 * Disproportionate Retribution
 * Embarrassing First Name: "Thaddeus."
 * Forceful Kiss: Just loves giving these to Rhonda.

Eugene Horowitz
"Voiced by: Christopher J. Castile (early season 1); Jarrett Lennon (later season 1); Ben Diskin (seasons 2, 3, and 4); Blake McIver Ewing (season 5 and The Movie)"

An extremely unlucky kid.

 * Butt Monkey
 * Catch Phrase: "I'm okay", said after something bad happens to him.

 * Throw the Dog a Bone: Arnold often tries to invoke this, but each time life tends to yank the chain.

Brainy
"Voiced by: Craig Bartlett"

An otherwise taciturn mouth-breathing nerd who seems to have a thing for Helga.


 * Abhorrent Admirer: To Helga.
 * Author Avatar: Word of God has confirmed Brainy is his voice's actor other self
 * Beneath the Mask: Brainy knows who Helga truly is.
 * Be Yourself: Brainy is in love with Helga, and no matter how many OffhandBackhands he gets, he never denies it.
 * Cannot Spit It Out: Literally, the Vader Breath asthma never let say anything more than "Hi Helga" before the Offhand Backhand
 * Determinator: Nothing can dissuade him to be near to Helga.
 * Hidden Depths: As confirmed by The book six of the series Hey Arnold! Arnold's E-Files Brainy is as eloquent as Helga… only that he cannot talk because his Vader Breath. Also, he is pretty good manipulating Arnold, loves poetry and is allergic to cats.
 * I Want My Beloved to Be Happy: Word of God says this is how Brainy ultimately feels about Helga.
 * Interrupted Declaration of Love: It's implied this is what Brainy is trying to say Helga before the usual Offhand Backhand.
 * Offhand Backhand: Helga frequently does this to Brainy.
 * Offscreen Teleportation: Being offscreen most of the time, it's pretty easy for Brainy to do this. Lampshaded in several episodes where he shows up behind Helga in the most improbable. places, such as on Elk Island, the haunted train, and even in an Alley that Helga made sure was empty.

 * Everyone Calls Him Brainy: His real name is never reveal.

 * Vader Breath

Sheena
"Voiced by: Francesca Marie Smith"


 * Granola Girl
 * Huge Schoolgirl: Easily the tallest girl in class; towers over many of the adult characters at only nine years old.
 * Satellite Character

Olga Pataki
"Voiced by: Nika Futterman"

Helga's older sister and the parental favorite, much to Helga's dismay (and Olga's too, as revealed in "Olga Comes Home"). At first glance, Olga appears perhaps too perfect: Successful, pretty, smart, and sweet and kind to everyone. But she's actually dangerously neurotic, melodramatic and out of reality, due to having to constantly live up to her parents' (well, her father's, anyway) constant attention and ridiculously high standards.


 * Bare Your Midriff
 * Broken Ace
 * Cool Big Sis: In the aptly-named episode "Big Sis", she becomes one to Lila through volunteer work. With her biological sister Helga, however...not so much, but only because Helga can't stand her. However, Olga's come through for Helga on several occasions.
 * Hair of Gold
 * Parental Favoritism: On the good end of it, which turns out to not be so good.
 * Sexy Schoolwoman
 * Stepford Smiler
 * The Perfectionist: Hasn't received an A- since third grade. In the "Olga Comes Home" episode,
 * Zettai Ryouiki

"Big" Bob Pataki
"Voiced by: Maurice LaMarche"

Father of Helga and Olga. Runs a local business aptly named "Big Bob's Beepers".


 * Abusive Parents: Emotionally to both daughters, but in completely different ways.
 * Gasshole: He belches and breaks wind on occasion.
 * Humiliation Conga: Helga was so disturbed by the "Orphan boy" line (see below) that during a gladiator-style event, she told Phil what Big Bob's weakspot was. Basically, she told him to go for the ankles, which sent Big Bob into a tub of gelatin - costing him the event and the overall win.
 * Basically any episode that accentuates his Jerkass qualities ends with him getting a solid block of hilarious karma dropped on his head. "Roughin' It" is another good example, where he ends up alone in his RV stuck with sunburn, swamped with bugs, and itching from poison ivy (not to mention having been electrocuted by his own faulty products earlier) while everyone else enjoys camping the old fashioned way.
 * Jerkass: Most of the time, he's this.
 * Jerk with a Heart of Gold: While he rarely shows it, he does love and care about Helga, and in some instances can help out other characters when needed.
 * Kick the Dog: His "orphan boy" line (referring to Arnold) in "Parent's Day". It's so mean it would be a Moral Event Horizon if he'd said it directly to Arnold (as it stands, he was talking to Helga and was just characteristically loud and uncaring about anyone else overhearing.)
 * My Name Is Not Durwood: Consistently calls Helga by her sister's name, and almost always gets Arnold's name wrong.
 * Parental Favoritism: To Olga.
 * Wouldn't Hurt a Child: While he would go for verbal attacks, Bob has his limits on bodily harming children, especially his daughter, Helga.

Miriam Pataki
"Voiced by: Kath Soucie"

Mother of Helga and Olga, Miriam is a depressed, constantly sleepy, seemingly ditzy housewife with an addiction to "smoothies". It's not uncommon to find her sleeping in strange places. However, she can be very competent and intelligent, but unfortunately it seems that being married to Big Bob has really brought her down.


 * Alcoholic Parent: While they couldn't state it outright, Miriam is obviously a heavy drinker, with the show using smoothies as a metaphor for booze.
 * Hidden Depths: She was once a world-class swimmer, won a bull-riding competition as a girl and can run the family business better than Bob can if she wanted to.

"Steely Phil"
"Voiced by: Dan Castellaneta"

Arnold's grandfather.


 * Badass Grandpa
 * Cassandra Truth: In "Girl Trouble," he flat-out tells Arnold that Helga constantly teases him because she likes him. Arnold naturally doesn't believe him.
 * Cool Old Guy
 * Genre Savvy/Meta Guy: He often describes the plot templates in play.
 * Noodle Incident: Phil was apparently an acrobat in a Russian circus.
 * Noodle Incident: Phil was apparently an acrobat in a Russian circus.

Grandma Gertie (aka Pookie)

Arnold's grandmother.


 * Bully Hunter: Wolfgang and Edmund didn't stand a chance against Gertie with her clowder of black cats.
 * Cloudcuckoolander

 * Only Known by Their Nickname: Usually referred to as "Grandma," "Pookie" or other nicknames. Her first name is mentioned
 * OOC Is Serious Business: In "Parents Day," she acts like her usual fun-loving, crazy self. After seeing Arnold so depressed over his Parental Abandonment, however, she snaps out of the role she was playing and acts far more subdued.
 * OOC Is Serious Business: In "Parents Day," she acts like her usual fun-loving, crazy self. After seeing Arnold so depressed over his Parental Abandonment, however, she snaps out of the role she was playing and acts far more subdued.

Mr. Simmons
"Voiced by: Dan Butler"

Fourth grade teacher at P.S. 118 starting in the second season, replacing the original Living Prop, Miss Slovak. Thinks of everyone and everything as "special".


 * Ambiguously Gay: Played by an openly gay actor, loves the theatre, and has a very delicate, effete personality. In fact, a character who may or may not be his partner even appears in the Thanksgiving episode.
 * Confirmed by Word of Gay.
 * Ink Suit Actor: A very glaring example on a show with otherwise very outlandish character designs; Simmons strongly resembles his voice actor, Dan Butler.
 * Nice Guy: One of the nicest adults in the series.
 * Only One Name: It is strongly implied, but never explicitly stated, that his first name is Robert (in the Thanksgiving episode, he wrote a play that was based on his own life; we meet every character from the play in person later on except for him).

Alphonse Perrier du von Scheck
"Voiced by: Paul Sorvino"

The CEO of Future Tech Industries, Scheck is a greedy and heartless businessman who wants to tear down Arnold's neighborhood to build a gigantic, immaculate shopping mall. Only appears in The Movie, where he is the Big Bad.


 * Affably Evil: Appears to be this at first, but it fades over the course of the movie.
 * Big No: After he sees that.
 * Corrupt Corporate Executive: Not only is he not above, the whole reason he wants to build the mall in the first place is to.

 * Green Eyes
 * Man of Wealth and Taste: A small running gag has Gerald voice admiration for Scheck's suit.
 * Slasher Smile: Most notably when he's.

 * Soft-Spoken Sadist: His voice is pretty unassuming and even somewhat soothing for a villain, but he tends to lose this when he gets mad.

 * The Von Trope Family
