Saw this Chaos Terminator at London Comic Con today

I think he was meant to be Horus, it doesn't quite show up on the photo I took but the red lights didn't quite glow like eyes when you saw them in the flesh, instead they lit his face up from the side just like some of the paintings of Horus. Also he had the eye and all that on the shoulders :)

Also this doesn't quite demonstrate how big the costume was, you could see this bugger from miles away as he stomped about :D
