Maybe it's just me but I really love Demolishor. While I agree $49 is a bit steep (I paid $41.65 ) I think his unique design is truly a breath of fresh air & his transformation is quite fun.
I'd certainly rather buy him than a repaint, the Barricade ripoff that is Sideways or the half transformed jet-bot, Breakaway. They did something new with Demolishor & I think it works for the most part.
