Beast Wars Grimlock is a redeco of Dinobot (seem to have misplaced him), transforming into a velociraptor albeit of an albino kind. Like Dinobot (who was first a Predacon before becoming a Maximal), Grimlock's tail becomes a spinning slasher sword. He was slightly retooled to have ratcheting shoulders and space for an "energon chip" rubsign.
Due to the limited nature of the blog program, landscape oriented pictures show up rather small on the post entry unless you click on it for an enlarged view.
