Adventure Time is an animated TV series on Cartoon Network that has been airing since 2010 and ended in 2018.
The Adventure Time Fandom usually appears in the form of Finn the human, the main character of the show, but has been known on occasion to take the form of other characters, including Fiona and Marshall from the genderswapped version of the series.
Adventure Time is physically very strong and she has a certain set of morals she lives by. She believes in justice and has a strong desire to make sense out of the unusual. She always prefers to show mercy until she decides who or whatever she is facing cannot be redeemed.
She prefers to face most challenges head-on and is very spontaneous in deciding which course of action to take. Her love for exploration and random adventure often end up with her getting in trouble, but she is skilled at coming up with ways to get out of it. However, she can be somewhat emotional when it comes to relationships and finds psychologically stressful situations to be particularly challenging.
Homestuck Fandom - Matesprit
It has been hinted that the Adventure Time Fandom may or may not be in a red relationship with the Homestuck Fandom, but this is something they are secretive about. Adventure Time's final episode recently gave a special reference to two of Homestuck's characters, which may have been a display of her affection towards him.
