If I wasn't making a combiner, this would be a repaint of Hardhead/Quake.
But I gots to have my combiners so this is a repaint of Rook with a Dreadwind head. I took the front wheels off and glued on some trimmed treads from a universe Dropshot. His ICBM is a titans Perceptor scope with the nosecone from a KO universe Seeker glued on. It pegs on in vehicle mode but just rests on the shoulder in bot mode.
