Baroque is a dog who has been taught understanding of human sign language by Glycocorp. It is his job to deliver messages from Glycocorp to the dogs involved. He is cocky, and loves to emotionally torture others. He thinks it is hilarious.
Dr. Ambrose is a genius and the mastermind behind this entire operation. She will do anything for scientific gain, and is cold and uncaring. She is the one who taught Baroque sign language, and she is the one who instructs his every move.
