When he first appears he is defeated when Captain Marvel hits him so hard he seems to knock the evil power from him, in the form of leaving Printwhistle and the four other villains in front of him, the four fade away quietly, but Ibac later returns when the evil spirits contact him. Captain Marvel whirls Ibac around so fast that the four evil spirits separate from him. Because he has not been able to defeat Captain Marvel, Printwhistle has not been obliged to give his soul to the devil, and has reformed, but being weak-willed, he has often been forced by other criminals into becoming the evil Ibac again.
