Valiant #15 December 1962 [11]

In "null," Louis Crandell, a lab assistant to Professor Barringer, becomes invisible after a laboratory accident involving electricity—leaving only his steel prosthetic hand visible in the air. As his mind fractures under the trauma, he spirals into megalomania, turning to crime in England before fleeing to New York, where he threatens the city with a bomb. His descent into chaos leads him into the underworld, where a confrontation with a gangster forces him to confront the truth: he may have been wrong all along.
