Shrunken Bones

Shrunken Bones is a villain of both Spider-Man and the Defenders.

History
Jerry Morgan was once a researcher in cellular biology. He was attempting to recreate Hank Pym’s shrinking gas independent of the Pym particle. His experiments was a complete success, but at a terrible cost: Morgan’s experiments shrank his skeleton and internal organs to a height of 4' 3, but left his skin grotesquely oversized. Embittered by his deformity, Morgan gladly joined Gorilla Man's Headmen.
