What do you get when two well-respected actors and long-time musical collaborators team up with an Eisner Award-winning artist to chronicle the life of a dog of vengeance? You get something odd, something edgy, something unique. You get Trypto, the Acid Dog. Born of water, born of fire, born of blood, born of acid, Trypto is unlike other dogs. In this series of offbeat tales, the canine avenger fights against those who would abuse Mother Earth and her creatures. Produced over the course of a decade, the complete run of Trypto stories is brought together for the first time in this 25th anniversary collection.
