Adam Clayton was a scientist that used his self created Vibra Light device to bombard himself with vibrating light molecules and speed up the molecules of his own body. This granted Adam the ability to run at speeds so high that Adam is undetectable to the human eye, thus granting Adam the title of Invisible Man. However using these powers also greatly enhanced Adam's aging process, causing Adam to age forty years in just a matter of days. At some unknown point Clayton passed away.
