Having celebrated the teaming of Marvel Comics' big ugly monsters from the early Silver Age in previous posts, it behooves me to include HULK ANNUAL #5, in which the heroic green goliath takes on six grotty grotesques from that period. One of them, the Living Titan, had already encountered the Hulk in a DEFENDERS story or two, and that was something of an in-joke, because in the year the Titan first appeared, his original name was-- the Hulk!
The other five critters had not encountered the Hulk before and probably not since, and like the cover says, they include smoke-monster Diablo, tree-creature Groot, mud-monster Taboo, generic space-alien Goom, and the electrical alien the Blip-- who was actually a benevolent fellow in his previous incarnation, something writer Len Wein evidently forgot.
