These are parts one and two of a very weird trilogy. For reasons that aren’t entirely clear, the Mad Thinker and Puppet Master agree to be led by Egghead on a campaign to go after Subby, Captain Marvel, and The Avengers.
But each issue of this three-parter end up being very important. It starts with Sub-Mariner #14, which brings back the original Human Torch and makes the early Sub-Mariner stories—from the 1940s, pre-Marvel—Marvel canon. It’s the start of the later idea of the WWII superhero group, The Inhumans.
And look how he uses his bracelet as a set of brass knuckles in the fight scene above. Badass.
In Captain Marvel, he fights Iron Man.
It’s a weak issue, but it ends with Captain Marvel being recalled to the Kree galaxy—cosmic stuff to come!
And the trilogy concludes in Avengers #64
