Xanderpocalypse by wlfgang213 reviews
Reposted: YAHF. After Xander's Halloween costume takes him away from Sunnydale, he returns home with knowledge, training, and experience the likes of which no demon could match. Given who he has become, nothing will ever be the same. No M/M slash, there will be one F/F relationship outside of canon, but nothing graphic. No Lemons or graphic sex scenes. NOT Ship of the Line.
