Billy

Billy is the given name of a goat-person in The Adventure Zone: Amnesty. The character is described as being mostly similar in appearance to Vincent, another goat-person who resides in Sylvain, but bigger. Billy was one of three goat-men who accosted Duck in the woods while Aubrey and Ned dealt with preventing a catastrophe with a tram lift.

During Duck's encounter with the goat-men, Duck attempted to use Billy (then unnamed) as a hostage to ward off the other two. Undeterred, one of them moved forward, stabbing them both with its weapon, and piercing through Billy's shoulder to reach Duck.

After the other two goat-men are chased off by Barclay's approaching vehicle, Duck makes the difficult decision to try and save the wounded goat-man. After transporting him back to Amnesty Lodge, Duck uses his basic veterinary knowledge to mend his wound.

When he comes to, the goat-man is unable to communicate or understand Duck or the others, instead bleating unintelligibly. Aubrey attempts to use her magic to bestow the goat-man with the ability to speak, but it's a mixed success: while he is suddenly now able to understand what is spoken to him, he is unable to vocalize, save for the name "Duck", and a couple of other words. It is at this point that he dubbed "Billy" by the gang.
