This guy is one of the two leaders of the Outcasts, a group of daemons which were created by Tzeentch as his special playthings... However he got bored of them and threw them away into reality. Now they are very grumpy and pissed off.
Made from some old
WoC sorcrerer and a Kroot hound. Scheme inspired by... a "troll", if you get my point
Not that good pics, but I hope you get the idea.
