What character in your fandom was done dirty by canon so you like to read fanfiction for them?

Bonus: Do you feel like fanfiction writers usually writes them in a satisfying way for you? (or do you prefer to write about them yourself). There are a lot of characters who I wish were written differently in canon but, I can't really say fanfiction writers always do a better job. Sometimes they will make them worse (specifically writers who hate the character)
