- You may be looking for the child genius Henry.
Henry was a security guard.
The Terrible Trio broke into the building Henry was guarding. They quickly beat him up, before opening the safe. The Fox mockingly congratulated him on his effort to stop them, and even gave him a stack of their stolen money as compensation—feeling that security guards made much too little. Henry threw it back in the Fox's face. The trio fled as Batman and Robin entered the room, and Henry encouraged them to forget about him and chase the thieves.
