Now see, that's just a list of character traits. From that, you can't very well make a conclusive statement because Mary Sues are caused by bad writing more often than not. The traits don't really matter, it's more how the world and other characters treat him.
Just from the description though, I'm wary. He seems to put to much emphasis on restrictions and flaw's (such as the restriction of not fighting opponents weaker than him) that suethors usually use to try and feel better about the character. You know, things they can point to and go "no, they can't be a mary sue, see? They have flaws."
Hey son, wanna' learn how ta' make witch balls?
