That is a confusing question...
In Fan fiction, a Gary Stu is a male version of 'Mary Sue,' a term used for characters who are perfect, know things they shouldn't, and nothing bad ever happens to them.
If there is actually a character in a game named 'Garry Stu,' can you specify the game?
Obviously. Why have a sparkly Gary-STu, when you can actually have a deep, layered character?
Stu Bennett goes by Stu.

Stu Nudelman goes by Stu The Wine Guru.
No you cannot find Gary in Pokemon black/white but you can find him in the kanto region.
