After seeing Chris transform into a large gigantic wolf, Peter was left confused for a few seconds. For one, he was unaware that Chris could even do such a thing. After hearing about the fight between him and Quinn, there was no mention of Chris turning his body into a full wolf.
Of course, Peter did know about his werewolf form, and understood that with that, his Qi, and all the training he had done that was how he had gotten so powerful, and yet, why was he now a wolf?
The thing was, just looking at it, he didn't look like any ordinary wolf, at least not the ones that Peter had seen. The sheer size of Chris was different, he was as large as a car.
Even though he was covered in fur, the outline of his muscles on his legs and more could still be seen, and the fangs on his two front teeth as well as the claws on his paws, were larger. Almost abnormally large, even for the size that the wolf was.
