This is another one of those early 1970s monster books that weren’t bad, but also really weren’t part of the Marvel Universe. I mean, they kind of were–when it was convenient or they wanted to sell books–but it was more that the characters became folded into the MU at later dates. The stories themselves don’t matter much, and I don’t intend to cover them here other than a mention, and then maybe the issues that matter.
Jack Russel got bitten by a werewolf in Marvel Spotlight #2, had a second adventure in MS#3, and then got his own book that lasted for several years.
It was pretty good.
