spoilers...
your mostly right, minus the decayed flesh part, just a skull with eyes and some exposed brain in a glass helmet looking thing. although what he looks like now after the fight is anyones guess. his insides went up like grievous in star wars, with an eye shooting out of his head. the problem with a decent picture of him is that becuase its mostly action there are huge double pages and not really any just of him. plus their too big to attach, so if anyone wants one email me or leave me a message or something.
