Alopex reminds me of Bludgeon: a slightly different and pretty much better looking version of an animal with an existing mutation. For instance, if you're going to mutate a hammerhead you might as well use Bludgeon again, but if you're mutating a nurse shark chances are you're going to want to make it a new character.
