That happens a lot. This is sometimes where it rolls back into; "Is it justified?"

I've literally seen characters that literally say in their profiles and sheets that they are perfect in all ways. Strong, beautiful, this that and the other thing. I will often dub them; "Miss/Mr Perfect" when referencing them. But it's justified in a way because they have basically created a mary/gary sue and it's just stupid.

Then you have people who are just assholes to any given character because they may top their own.
