Here now is a taste of a few models that I've had in my collection since the dawn of my tabletop gaming experience and occasionally see use on the table as I try out different army lists.
Emperor's Children Land Raider. Back then, there was only one model for the Land Raider, Rhino, and Predator. If you wanted it Chaos, then you had to convert it because there were no Chaos accessory sprues. So with a few skulls it becomes Chaos. At least that was the theory 20 years ago. Now skulls are on everything.
Not a pleasing sight to be coming towards you. Knowing what I know now, I'd recess the Heavy Bolters back further into the eyes.
Here are a few pictures of my Chaos Predator. One question I always get from people who know that the Blood Angels are my favorite army is why is there a Blood Angel in your predator. The Emperor's Children was the first army I collected before I wised up and became obsessed with Blood Angels. Our game night host, Mr. B. Woods, had a Blood Angels army and I was alway fighting against him so it seemed reasonable to impale one of his marines on my tank.
