What do YOU consider to be a Mary Sue/Gary Stu? I want to know what your definition of a Mary Sue is.Theres always a deeper meaning to something,even a Mary Sue(& Gary Stu). (Lila particularly tried to be a Mary Sue in a way.Cant say I hate her though.)

A character with a perfect life who the answers come to.

To me, A Mary Sue means that the character is perfect in every way, is loved by all the other characters, a cliche back story and is basically invincible.

A character meant to be perfect, and to surpass every other character. Usually, they claim every cannon character likes them, and usually have a romantic relationship with a canon character (however, that is not always there). They are also known to have extremely powerful attacks, and (usually) a tragic backstory.
Ex: Cutie the Kitten (however, this person has changed, and is no longer a Mary Sue)

See also, Anti-Sue/Stu: Opposite of a Gary/Mary, they claim their character is See More hated by society, and are seen with tragic backstory. This usually gains the pity of other characters. The Anti has extremely powerful attacks, similar to the Mary/Gary.
Ex: Most Creepypasta characters.

My definition of Mary Sue is a mixed emotion- special person.She could be a super hero.That's just what I think though. XD
