Guy's muscles were still huge and strong, in fact they were a little larger than normal.
The problem was they were covered with blue scales!
Guy ran his hands over them (noticing they had claws and knobblier knuckles) and felt them to be leathery but shiney. Looking down at his abs, hesaw that they were broader, but now in the form of a segmented underbelly.
Climbing out of bed, he saw he had thicker legs and huge feet (twice as big as normal and also clawed) and a long tail ending in a brush.
Rushing to the mirror confirmed it. In his reflection he saw he had a slightly longer neck and a horned dragon's head of the oriental variety (he still managed to hold on to his hair).
