Bat-Mite comes to Earth and gives three crooks super-powers to make them more challenging to Batman and Robin. But, a bump on the head blocks Bat-Mite from using his powers against the crooks, and the three opponents may be more than the heroes can handle. The strongman, the rubberman and the human cannonball are unstoppable with their powers combined and the heroes are captured and left to die. Unsurprisingly, Batman devises an escape and warns Gotham of the 3 criminals' presence in the city. With the city alert the three criminals split up to steal as much as possible before fleeing the country. With the criminals separated, Batman and Robin set about the task of capturing them all. Batman first tricks the Strongman into punching himself, knocking him out. Later, he tricks the Rubberman into bumping his head on a doorway as he tries to dodge one of Batman's punches. Finally, the Dynamic Duo are unable to stop the human cannonball, but Batm-Mite's powers return in time to change the crook back to normal and thwart his efforts to kill the dynamic duo. Batman then realizes that Bat-Mite got his powers back when they confronted the Rubberman, but didn't use them so that Batman and Robin could continue to fight the criminals for his amusement. Fearful of Batman and Robin's retribution, Bat-Mite returns to his own dimension predicting his inevitable return
