Warp Fiends Chaos Terminator lord - Ghastus Draik.
The mandatory Hq Choice for my little WIP chaos marine warband is this metal terminator mini, I bought this back when they were first released end of 2nd edition /beginning of 3rd?? he was one of the few miniatures to survive me leaving the hobby in my middle teens.
I gave him a quick repaint to match the warp fiends colours and that was that. Armed with a lightning claw and a combi melta ( I still need to do a little painting on his gun) I particularly like this head option as well. The first (post rogue trader) chaos marines were my favorite of my little armies back in the day.
