Not crazy about testing an experimental new serum on himself, he managed to find an ideal subject...the cadaver of Denny Colt, a rookie police officer recently slain in the line of duty. And so, just before this young man was buried, he was given a "modest injection" of the immortality serum by Coroner Octopus. *Source: Back of card.
