So after purchasing a loose Iceman from the X-factor pack so I could steal his belt (I plan to put it on the X-factor Ice-man when that finally gets here, since it has a far superior paint job) I thought I'd put the body to better use.
Firstly, I used my new Dremel to cut down the neck and carve a new neck peg lower down on the figure (the neck on that body was too long, it didn't look right with the smaller Xavier head) and I painted the blue segments of the costume in a semi-translucent blue paint.
Admittedly, it's not my best paint job, but this was more an excuse to try out the Dremel then a serious custom. Still, it turned out ok, and I'll probably swap it with the suited Xavier every so often.
P.S. No prize to anyone who can guess where I got the costume from.
