I was skimming through a couple of the TPB's and came across an Autobot I hadn't seen before. He seemed to some kind of big armored tank/transport and was with Kup's group. The thing that stood out was, he was a lot taller than Optimus but he had to be the widest in relation to height transformer I have seen. He seemed about 4 times wider/bulkier than Optimus. I had never seen him before. Who was this? What's his story?
