Dr. Karos was a scientist who created a plastic that could become invisible.

History[]

Dr. Karos developed an invisibility plastic with his partner Sam Giddell. He was originally going to sell it to Wayne Tech, but after discovering that the material was toxic, he withdrew his offer. Karos passed away sometime after.

After Karos' death, Giddell tried to fix the plastic's problem, but failed. Some of it was then stolen by Lloyd Ventrix, who used it to commit various crimes without being detected.
