It's not really a "character type," but it's a plot device that's often used to create conflict between characters and it really bugs the shit out of me: the liar revealed. The story where, whether by accident or necessity, the protagonist has lied about something and at the most crucial moment the people they have lied to discover the lie, feel betrayed, hate the protagonist, and then the protagonist has to do something to earn their trust again and prove they were trying to do the right thing.
It bothers me because you can see it coming a mile away, you know how it's going to end, and it just makes whatever direction the character development was taking and bottlenecks it down the same path a million other stories have gone. It kind of makes all other character development irrelevant because no matter what you've established before everyone ends up slipping into those predetermined molds: Protagonist feels bad, other characters feel betrayed and angry and make stupid decisions because emotions, protagonist saves the day, other characters forgive protagonist and learn to trust again, everybody is happy. It's just soooo boring, and makes me give up on seeing any more character development once they set up the lie.
