Red Cat

Origin
The Blue Beetle was not the only one Dr. Franz chose to give vitamin 2x.

While attempting to fight a fire, Fox City Firefighter, Cabe Levin, was injured when part of the building fell on him and laid near-death in the hospital. He received a visit from Dr. Franz, who had a plan to save Cabe's life.

Dr. Franz administered a strange treatment. Cabe was given the secret experimental vitamin 2X, a super drug that endows its recipient with super strength and healing abilities, increased speed, heightened senses, and enhanced intellectual capacity. Under the drug's influence, Cabe Levin rapidly recovered from his injuries and returned to the fire brigade the next day. He explained the injuries away by claiming that debris made it look like he was gravely injured.

Like with the Blue Beetle, the effects of vitamin 2X were temporary, and he never carried a supply with him.

The Red Cat fought crime, in its many forms, until the early 1950's.
