Remember Giant-Man? One of the first black superheroes? He helped kick down the door to racial barriers.
In this multi-issue tale, he is hired by Stane International to work on a Pym Particle project. Dr. Nemesis is the main villain…
Nemesis hired Goliath as protection, another growing character, so there’s some good “big people” fights.
But the real importance here is that we learn that the reason people become lighter/heavier when the Pym Particles grow/shrink them is because they import/export body mass into another dimension. So there’s a dimension where body fat goes? Ewwwww.
