Therefore he had more power but we really never find out what made him look like he did. I thought that as well but was unsure if an Alpha could only do that with the Beta's in his pack or if any other werewolf was game. But if any werewolf was game than there would be no limit to his or any other Alpha's power.

It was never really said that it could only be killing a pack to give you power and thats what it seemed like Deucalion seemed to have limitless power. Heck the Darach needed him to be powerless to even try to kill him.
