Is Your Character A Mary Sue?

Explanation
Unless your character is a persona/fursona or a type of character that is SUPPOSED to represent its creator, its best to avoid it all together. Theres nothing wrong with giving your character some traits that you personally can relate too, just try not to add too many.

Explanation
When making a character, you should never add characters in their story simply to make the main character look perfect or better. The characters that revolve around your character should have a real and interesting purpose to the story. Something I tell alot of people to do is to give their character a rival or someone they have a long line of history with, whether it be good or bad.

Explanation
Nobody is perfect, and your character shouldn't be either. Sometimes it's hard to make a charcter that can't solve every problem, especially when your character is the protagonist and not the antagonist. The simple solution to this, is to give them situations in their life that aren't perfect. Perhaps maybe an old friendship that was broken because your character had a flaw that their ex friend couldn't accept (for example : anger issues or a violent nature)

Explanation
Once again, flaws are human. And nobody's perfect. It's hard to relate to a perfect person because nobody IS perfect.

Explanation
Being inmortal is probably one of the most commonly seen things in a Mary Sue. And although i have marked "no" as the correct answer, I do believe that it is possible to make an immortal character that is not a Mary Sue. If executed correctly, immortality can be an interesting device to your characters story. For instance, a term I use alot is "Limited Immortality", meaning that a character is only immortal to an extent (meaning that there is a very specific weakness in this world that can bring harm or even death to the character).

Explanation
Once agains, there is a right and wrong way to go about royalty. But if you're still learning how to write and create characters, it's best to avoid this trait.
