Hilda (aged up)

In all incarnations of the franchise, Hilda is an extremely adventurous and fearless girl. She loves to draw in her sketchbook and is very kind to nature. She is shown not to get scared easily by monsters and can outrun and outsmart them.

Hilda is sometimes rude but is usually very friendly and generous. Her rude side is played up more in the graphic novels, where she is known to frequently argue with her mother or to easily get annoyed when things don't go her way. She is also more prone to mischief in the graphic novels (like taking her role of pretending to be injured for first aid practice of the Sparrow Scouts too far or going on secret adventures without her mother knowing). When the graphic novels were adapted for the animated series, these negative traits were toned down in Season 1 to make Hilda a nicer girl. Season 2 partly restores her characterization from the graphic novels, with Hilda getting into some arguments with Johanna there.

In "Chapter 6: The Nightmare Spirit", it is revealed that there is one thing that frightens her; riding a bike, something she never had learned. This was used against her by David's Marra. In the graphic novels, this fear is never brought up, but in the novelization it is turned into a subplot for "Hilda and the Nowhere Space"; early in the book, Hilda comes up with various excuses for not having to use her bike (including that she doesn't want it to get dirty). Then she encounters the Marra who just like in the animated series, uses this fear against her for a nightmare. After this encounter, she tries her best to overcome her fear and slowly succeeds. By the end of the book, she has mastered to ride a bike, and is thrilled by the thought of all the places she can go to now. As of "Chapter 6: The Old Bells of Trolberg", Hilda can ride a bike just fine, and even remarks that she is getting better at it.

Hilda hates having to disappoint people, especially her friends or her mother and always tries her best to help and support others with their needs, occasionally taking risks in order to fulfill one's request. She is very brave and caring, as described in the official Netflix description. She is usually very happy and generous.
