"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.

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.

Upon saying "Ibac!", Printwhistle is transformed by green fire into Ibac - possessing from the evil spirits:

  • Ivan the Terrible - Terror
  • Cesare Borgia - Cunning
  • Attila the Hun - Fierceness

In addition, Ibac also has superhuman strength and stamina. Saying "Ibac" again, will transform him back into Printwhistle (as a result, prevents him from saying his own name without losing his power).
