Quote:Thing is, the Xander-is-Everyman bit is driven home so much that people who would normally write self-insert fics are drawn to Xander-Sue instead.
I don't know off-hand of any stories centred on someone else's Halloween experience, but then as the only main character to end the show nominally normal, he's the one who most in need of a power-up - or so it would seem, quite falsely, to the many authors who don't get the point of his character.
And as for Halloween: in-canon, X is the only character who is shown to have retained some of the skills of his altered persona, long after the occasion. It crops up on several occasions. So the default assumption is that he's got some kind of minor mojo that let him and him alone hang on to the costume -- in light of which, swapping just his out seems like a logical spot for a divergence.
