G-CELLS AND MUTATIONS

G-Cells are mutated cells that come from Gojira along with its offspring. (Redmass, Humanoids, Etc) When G-Cells come into contact with animal cells or human cells, they begin to modify the genetic code of the creature and mutate its cells into G-Cells. The G-Cells also rapidly multiply, increasing mutation speeds. The mutations vary, but most of the time when humans are mutated from G-Cells they mutated into Redmass variants or Humanoids.

This animation shows how G-Cells mutate other cells and rapidly multiply.
