The giant baby worked at the DA's office. With her rattle in one hand and her bottle in the other hand, she would rattle the cages so that Batman wouldn't have to go it alone all the time. He was sick of doing everything.

The guy/girl with the six pack abs, the crown, and the V shaped torso came off as someone with a tough image, but was actually a baby with a loud rattle in one hand and a bottle in the other hand underneath his/her skin. He/she was a giant among babies, a giant baby.
