Stanley Printwhistle

Stanley Printwhistle is the mild-mannered human host of Ibac, a DC villain who transforms into a powerful monster by invoking the name IBAC, gaining the evil traits of Ivan the Terrible, Borgia, Attila, and Caligula — making him a recurring foe of Captain Marvel and Billy Batson.

Stepping out of the Bronze Age in 1981, Stanley Printwhistle is a DC Comics creation from the sharp creative minds of Roy Thomas and Rich Buckler, introduced in the pages of DC Comics Presents #34. Over a surprisingly enduring stretch reaching all the way to 2021, this character has woven himself through some genuinely classic corners of the DC universe, appearing in The Power of SHAZAM! and Adventure Comics alongside the likes of Captain Marvel, Billy Batson, and Ibac. With only eight catalog appearances, Stanley is the kind of deep-cut discovery that rewards the dedicated reader — a quiet piece of DC's rich mythological tapestry that serious collectors will recognize as a sign they've really done their homework.
