Characters in Edgar & Ellen.
Beware of book spoilers.
The eponymous troublemaking duo. They are 12 years old at the start of the series.
- Freudian Excuse: Their parents abandoned them many years ago and townsfolk never really paid much attention to them, so they had nobody to care about them or teach them right from wrong.
- Friendless Background: Due to their distaste for most Nod's Limbsians, the twins had never made a friend and only hung out with each other before the events of Pet's Revenge, where Ellen befriends Miles Knightleigh. In High Wire both twins befriend The Midway Irregulars.
- Gadgeteer Genius: Both of the twins to some extent, but especially Edgar. Exaggerated in the animated series, where they build much more elaborate contraptions.
- Hairstyle Inertia: They have the same hairstyles since infancy.
- Half-Identical Twins: The only physical difference between them is that Ellen has long hair and no fringe.
- Limited Wardrobe: Literally all they ever wear is their striped footie pyjamas. Even when they do wear other clothing, they always wear their pyjamas underneath.
- Non-Standard Character Design: They have bigger eyes than everyone else, have sharper features and are taller than most kids in their age group.
- Parental Abandonment: The twins' parents apparently left years ago on an around-the-world holiday, and haven't been heard from since. The twins never really questioned this, oddly enough.
- The Pig Pen: The twins don't really bother much with hygiene.
Ellen's younger twin brother. He is a skilled scientist, inventor and escape artist. He plans many of the twins' schemes and diagrams.
- Idiot Ball: In Split Ends. He goes a bit unhinged in his isolation and ends up derailing his plans for some needlessly complicated personal engeance, which both fails and lands him in deeper trouble.
Edgar's older twin sister by 2 minutes and 13 seconds as well as the leader. She is essentially a mad scientist, particularly when it comes to flora and fauna.
- All Girls Want Bad Boys: In Pet's Revenge Ellen reveals that she likes "handsome rebels".
- Big Sister Instinct: On rare occasions, she looks out for Edgar, like in "Crushed" and "The Great Edgarini"; for the record, she's 2 minutes and 13 seconds older than him.
- Dreadful Musician: Ellen thinks she can sing, but to the others she's horrible.
- Hair Decorations: She always wears her trademark red bows.
- Hates Being Touched: In both the books and TV series, she is shown to dislike hugs.
- Real Women Don't Wear Dresses: She only wore a dress for Ronan and Dahlia's wedding and politely refused Madame Dahlia's offer of making her dresses to wear for each day of school.
- Stronger Sibling: She's tougher and more independent than her brother.
- Tsundere: She actually does care about Edgar and her friends, but she seems to be near unable to express her affection for them.
Pilosoculus (a.k.a. "Pet")
Edgar and Ellen's pet and Augustus Nod's best friend.
- Meaningful Name: Pilosoculus is latin for "Hairy Eyeball".
An eccentric retired Bavarian circus performer, he is Edgar and Ellen's groundskeeper and, prior to the events of Nod's Limbs, the only person who protected the twins and Pet.
- The Dreaded: To the twins. In the show and for much of the books, he is the only person they fear.
- Meaningful Name: He gets his name from St. Ronan the silent.
- Perpetual Smiler: He never stops smiling unless he is extremely sad.
- The Quirt One: He prefers to not speak unless it's absolutely necessary.
- Scars Are Forever: He now has a prominent scar from when he had to save the twins in "Nod's Limbs.
- Something Else Also Rises: In one of the "Heimertz Family Album" shorts, one of the young Heimertz's suspenders pops open after he receives a kiss on the cheek from a woman he just saved.
The over 200-year-old unintentional founder of Nod's Limbs and the original owner of the Tower Mansion. He is also Edgar and Ellen's foster father.
- 100% Adoration Rating: He is simply adored by the Nod's Limbsians.
- Friend to All Children: He is rather kind to the twins and The Midway Irregulars. He was only mean to Miles because he was a Knightleigh, although it has been implied that they are on good terms now.
- Limited Social Circle: Due to his hatred for people, his circle of friends consists on just Edgar, Ellen, Pet, Heimertz, Madame Dahlia and Benedict, although other Nod's Limbsians have tried (and failed) to make their way into it.
Stephanie's 9-year-old younger brother.
- The Unfavorite: His family doesn't pay much attention to him for being nice.
The sweet girlfriend and later wife of Heimertz.
- The Cavalry: She got two small (yet awesome) ones in High Wire. Ellen went looking for a gemstone in Madame Dahlia's Man-Eating Plant's mouth, after it swallowed Ellen Madame Dahlia rescued her during her performance.
- Defrosting Ice Queen: In High Wire she had a cold attitude towards people until she is reunited with Ronan, her long lost lover.
- Scare 'em Straight: It is implied in High Wire that she used Gustav to scare the circus children into behaving. It didn't work with Ellen though.
Citizens of Nod's Limbs
- Gold Fever: The town eventually succumbs to this in Nod's Limbs, after many days of working on the treasure hunt together finally wear down their spirits.
Mayor Knightleigh's 13-year-old daughter.
- Adaptational Heroism: In the TV show, she's more of The Rival than an actual villain who isn't that much worse than the main characters, even sometimes teaming up with them or having some respectful interactions with them.
- All Girls Want Bad Boys: It can be implied that in the TV series Stephanie may have a thing for Edgar. In the Valentine TV special, Stephanie glares at Edgar and Ursula as they dance together and is very happy when Ursula dumps him. Through the rest of the series, she doesn't treat him as badly as Ellen. Averted in the books, where she wants to kill both Edgar and Ellen.
- Friendly Enemy: On her good days in the TV show. On a deeper level, one episode even focused on Edgar and Ellen coming to the realization that if Stephanie was gone, their lives would be empty without her and their rivalry.
- Parental Favoritism: She's her parents' favorite.
The Midway Irregulars
A young band of pranksters conformed by the Heimertz Family Circus' youngest members.
- Deliberately Cute Child: They pretend to be innocent in front of others, but in truth they are almost as mischievous as Edgar and Ellen.
- Every Proper Lady Should Curtsy: Imogen and Mab curtseyed when introducing themselves to the twins.
Gonzalo Winston Heimertz
A clown apprentice.
Mab and Merrick Heimertz
Brother and sister acrobats.
- Flat Characters: Besides them being acrobats and pranksters, we know little to nothing about them.
Ormond Heimertz (a.k.a. Ormond The Impossible)
Ronan Heimertz's cousin. He was the Heimertz Family Circus' escape artist before he betrayed them.
- Big Bad Duumvirate: Ormond Heimertz and Mayor Knightleigh in the original six books and with Stephanie in the Nodyssey trilogy.
- Black Sheep: He hated his life at the circus, never got along with his fellow circus artists to the point where the entire circus distrusted him and he couldn't move unnoticed or talk to them and eventually he rejected his family and left them by faking his death. Nevertheless his family expressed great sorrow for his death.
- Would Hurt a Child: He wants to kill Edgar and Ellen and has no problem with putting several children, among them his own relatives in fatal danger.
