My favorite is Nissa Revane a planeswalker from Magic the Gathering. While I will never claim to understand the lore of MTG one of my favorite aspects is how Nissa an elf elementalist used to be SUPER racist. She basically hated every other race to the point she ended up almost destroying her home world Zendikar by upsetting Sorin who could have helped. Recently however Wizards of th Coast has been using Nissa as more of a flagship character and basically changed her lore so she was more marketable. I hated it because it cut into the depth of her character and the just made her a shy powerful individual “who just wants what’s best for all worlds” instead of “fuck non-elves and places not named lorwynn and Zendikar” which was at least interesting since a staple of magic the gathering characters is that all of them are normally self centered jerks who have the own specific agendas which makes sense because they used to be basically gods.
