She is compassionate and caring, always looking out for her, mother, friends and the creatures she encounters in. She's brave in the face of danger and has a natural inclination towards problem-solving, often using her creativity and resourcefulness to overcome challenges. Sometimes she can be a little sassy towards other people if they overlook the creatures around the city named "Trollberg" as dangerous, but she tries her best to see them as good and harmless. Overall, Hilda's personality is characterized by her adventurous spirit, kindness, and resilience.

Johanna (Hilda's mother) is portrayed as a caring and supportive mother who deeply loves her daughter, Hilda. She is depicted as intelligent, resourceful, and level-headed, often providing guidance and wisdom to Hilda as she navigates through various adventures and challenges. Johanna is also shown to have a strong sense of independence and resilience, as evidenced by her ability to adapt to new environments and situations, such as when they move to Trolberg. Overall, she is portrayed as a warm and nurturing figure who plays a vital role in Hilda's life.

Kaisa appears to be a young female adult witch who is known for being the keeper of the books at the Trolberg library. Kaisa is usually calm, but can be rather strict with rules. She has the uncanny ability to always know exactly what book people are looking for, even before they can ask her about it. She sometimes also has some feelings of insecurity about her abilities as a witch, believing she wasn't the witch she was trained to be, and to think she would dissapoint her teacher, Matilda Pilqvist (a.k.a Tildy). But with some help from Hilda, she along with Tildy proves that Kaisa never let Tildy down and she's happy to be her former mentor. Kaisa seems like a very calm and kind person who is content with most things, even if it means offering someone information, advice, or a task to handle and has a little sense of humor.

Frida is strong minded, intelligent, and highly organized, and always makes detailed plans for everything. She is prone to panic if her plans are ruined by unforeseen circumstances. She is also competitive, always wanting to be the best. However, she tends to overthink things and tries too hard to be seen as perfect. This causes Frida to severely doubt herself, and eventually her insecurities led to a huge argument and argument between herself, Hilda and David

David is a young boy who tends to be quickly scared and easily distracted, as well as a bit clumsy. It often takes his friends' encouragement to get him over his fears. He has very little time for selfishness, laziness, and cruelty, especially after hanging around with Hilda and gaining more confidence in himself. He's also able to sing and he's pretty good at it. As time wnet on, David seemed to be a bit more confident, easy going and more behaved to not being a scaredy cat all the time, though his original personality occasionally resurfaces when he is faced with a scary situation.

Alfur is a side character and a friend to Hilda. he is shown to love writing reports about Trolberg to the other Aldric elves. He is mostly known for paperworks and contracts, such as contracts for the exiles from the "The Lost Clan" and paperworks so that other humans can see him, such as Hilda and Frida.

The Narrator is known for being the person who narrates every story for each episode/chapter of the series. It is unknown who he is and what does it look like, but it's up to our interpretation on how their voice sounds like. 

He's known for being the fireman for Edward the blue engine

Just a regular passenger, nothing too special with him.

Flying Scotsman is a polite and proud engine; however he can be pompous and somewhat smug, like his brother Gordon, the big express engine. Despite being friendly with Thomas and giving him a pep talk, he thought that no famous engines came from Sodor, and indicated that he viewed Sodor engines with low expectations. He later changed his mind after seeing the Sodor engines competing at the Great Railway Show, realising they were made of "sterner stuff" than he initially believed. Scotsman enjoys teasing Gordon, referring to him as his "little brother" to annoy him, using his catchphrase as his own, or bragging about being invited to the Great Railway Show. He does care for him though, as shown when Gordon was overheating during the race, and Scotsman urgently warned him to stop.

Emily is an emerald tender engine who lives and works on the Island of Sodor, and is the North Western Railway's number 12 engine. Emily is a kind, caring, helpful and intelligent engine, who speaks with a Scottish accent. She is sensitive to the feelings of others and is quick to apologise if she wrongs someone, whether knowingly or not. She will stand up for other engines if they are being teased or treated unfairly and is unafraid to speak her mind, even to authority figures. Emily often acts as a level-headed voice of reason, particularly when the other engines jump to conclusions or when a friend needs moral support. She is also a very competent, clever, adaptable and quick-thinking engine, and as such is often relied upon for advice, a trait which eventually led her to becoming the railway's official "safety engine".
