In summary:
A Mary sue is usually a main female character that is too perfect, or has literally no flaws. The problem with that is that it feels like it was made by someone underage or someone with horrible script writing skills
Examples would be: Rey from Star Wars, Korra (forgot where she was from), or Captain marvel

how it feels to have mary sue characters who are male and female

Aight

Every time I make an OC I give them flaws

If they're super overpowered, I give them one huge flaw, like one of my OCS, imagino, is basically able to do literally anything, and I mean anything, but he can only appear in people's dreams and can't affect any part of the outside world

Qhat

I never do mary sue type character. i mean when i do i realize real quickly thats its pure shit and i add weaknesses and shits and other thingies that makesit more interesting.
