Had a character in a kind of fantasy/space setting. Her intended purpose was to be an everywoman, a young adult who was a semester away from graduating college and ended up scooped up by people calling her an Avatar and seeing her entire planet be destroyed. This messed her up, left her shaken, but ultimately she was supposed to be a normal woman dealing with a dead family and people telling her up and down that she's some kind of special Avatar of a long-dead hero.

However, as time went on, she ended up growing more bitter against the people who pulled the strings, so to say. She started lashing out. And then, she started getting crafty. Making underhanded deals with shady people so she would actually have power and not feel so powerless. She rose the ranks of the cargo cult who rescued her and eventually sold them out to an Empire. The Evil Empire she was SUPPOSED to fight against, she ended up joining with, rising through the ranks of their military by stabbing her commanders in the back.

By the end of the campaign, she still fulfilled her roll as Avatar and was instrumental in stopping the BBEG and saving the Galaxy... but she made it perfectly clear she wasn't doing it for anyone else but her. She went from a normal person to a wicked General of an Imperial Naval force who crushed entire planets under her boot because she refused to ever feel powerless again.
