In the 1970's Marvel started their horror franchise and success with their main stars Dracula, Werewolf and Frankenstein's Monster led to a series of characters who had a far shorter initial run, six of whom are featured here.
The Living Mummy, an obvious choice as the missing Universal monster, had better longevity than most included here. He starred in 9 issues of Supernatural Thrillers and allowed Marvel villain The Living Pharoah to re-appear. The mummy N'Kantu was an African prince buried alive and several tales feature flashbacks to his past life.
Brother Voodoo features in 9 tales including a Team-Up with Spider-Man, some of these were reprinted in Essential Tales of the Zombie.
There are 4 tales with Gabriel, the Devil-Hunter a one-eyed former priest turned exorcist battling demons across the globe. Written for one of Marvel's horror magazines these were aimed at an adult audience so are more graphic.
The Golem, after being dug out of the desart sand, only appears in 3 tales including one featuring The Thing.
Modred the Mystic and the Scarecrow likewise star in just 3 tales here, including Two-In-One with The Thing. Modred a magician from Arthurian times who is disrturbed from his sleep in a cavern on the Isle of Wight, he is also important in the early years of Spider-Woman.
I loved the idea of The Scarecrow as an image painted over that of a demon to keep the demon imprisoned and had all of the 3 Scarecrow tales when they first came out as the covers were superb.
Several of these characters returned to the Marvel universe in later years, to mixed receptions but it is nice to have their original tales collected together.
For Marvel Horror 3 how about Morbius, the early Tigra tales, Man-Wolf and It, the Living Colossus.
