Is your character a Mary-Sue/Gary-Stu?
Now, some people have OC/s (original character/s) and some are... OP (overpowered) to say the least. These creations are often hated and looked down on. A good character normally has a good colour palette (the colours go well together) has both good and bad traits and has reasoning to their actions/powers, just to name a few. (There are rare exceptions for these standards.)
Do you think that your character has the possibility of being a Mary-Sue/Gary-Stue (the horrible internet nickname for a perfect character. I myself don't like using those words, but there aren't many substitutes, so let's just stick with the official terms.) Good luck
