Origin[]
"Stinky" Printwhistle planned to blow up a bridge and then loot the oncoming train. The plot was foiled by Captain Marvel, who threw "Stinky" off the bridge. In a deal with Lucifer, Printwhistle sells his soul for the power of the most evil men in history. He fights Captain Marvel on several occaisons; the first of which, he was defeated by Captain Marvel knocking the evil spirits out of him. Ibac was also a member of Mister Mind's Monster Society of Evil.
