Appropriation of Characters

Have you ever taken a problematic character in genre fiction, altered them to fit your headcanon, and taken them to your heart as a favorite?

There are so many female characters from when I started reading comics that so clearly had never had a female influence touch them, so many were so full of gender nonsense, but I remember very clearly finding ways to love them anyway, even if it meant inventing my own backstory and adventures for them.

I can only imagine what it must have been like for lgbtq or poc folks.

But everyone can play, did you ever take a character and make them your own and still have affection for them, even if their stories or character were problematic?

If so, who?
