It starts with a bang, a typical American small town circa 1949 is turned into a slaughterhouse. Corpses piled up, satanic runes written in blood, gnawed bones everywhere.
The sole survivor is a young catatonic woman who eventually gives birth to our hero Ray Stoner. He grows up, serves in Vietnam where he hulks out and slaughters a platoon of Viet Cong. Eventually he discovers his half-demon heritage and sets out to stop his kin from conquering the world.
This series first came out in early 90s and frankly felt dated then. The whole concept, half-demon psycho Vietnam vet, feels like something out of the 70s and frankly has not aged well. The concept is solid enough but is undercut by some very conspicuous plot devices, an interdimensional city which the evil demons cannot enter (but Stoner can) or a magic well that functions both as a scrying pool and an infinite potion of healing for our hero.
Overall the Breed series as a whole has some nice art (it's Jim Starlin, of course the art is great) but doesn't have much to say. The 2nd book seemed like padding, and the 3rd, which came out nearly 20 years later has a bizarre crossover that manage to be both a deus-ex-machina and break the 4th wall.
If you're a big Starlin fan (and I am) add a star otherwise you can probably give Breed a miss.
