Hunky/Brooding/Mysterious Guy:
Mystery does not mean substance. They probably also need a restraining order (ex. Edward Cullen)

The Mary Sue:
The perfect main character who always has the best intentions in mind. She's perfect, but she doesn't see it. Everyone love her, but there is no big struggle and this makes it hat to relate to

The Popular Girl:
Usually mean and hates the protagonist for no reason. A mean character does not need to be a girl, and there should be a reason as to why the main character's hated. This character needs to make sense in your story

The Nerdy Sidekick:
There needs to be more about this character than being nerdy. Maybe give them a moment of bravery, but make sure that their existence means something
