Peachy Sue

A female character in a story (usually fiction) who checks off all of the boxes of being a 'Mary Sue,' but people hypocritically refuse to acknowledge their status as one. This is due to either the story being a parody, or the character being 'likable.'

Princess Peach from the Super Mario Bros. Movie was a Mary Sue, but people claim she wasn't because they liked her a lot... let's just call her a Peachy Sue instead then.
