This is not actually my plog, but that of my brother's. He's a veteran of about 15 years in the hobby and has collected Chaos ever since the humble crazyness of 2nd ed. Even back then he was the only one in our group to have a fully painted army (about 3K pts of chaos, i think). He also used to build our terrain, which was pretty much awesome during a time without internet resources or GW buildings.
Anyways, most of his old army has been shelved only to modernize it with current minis. Still, he was always unsatisfied about how the current CSM are plain spiky bobs and don't represent the hellish vision of them represented in their artwork. So that's when he started converting and kitbashing. Not to forget painting, as he has taken part in the last 3 german Golden Demons, although unfortunately without success.
But I know you are here because you wanna see pictures, so here it goes:
TL;DR: lots of converted chaosy stuff
He built this Kharn for the GD 2010, because the old mini is somewhat dated. It is based on an older artwork of Kharn that some of you might be familiar with.
Hope you guys like the Betrayer in his converted glory.
