Baby-Doll is a former child star who suffers from a rare condition that has kept her locked in a child's body. Because of her condition, she has never been able to find lasting love or acceptance. When she meets Killer Croc, who is impressed by her toughness and intelligence, the two form a bond over their shared experiences of being outcasts.

However, Batman is on their trail and is determined to stop their criminal activities. He soon realizes that the relationship between Baby-Doll and Killer Croc is not as simple as it seems. Baby-Doll is using her childlike appearance to manipulate Croc, and he is conflicted between his love for her and his desire to do what's right.

In the end, Baby-Doll is arrested and Killer Croc returns to his life of crime alone. Batman is left to wonder if he should have been more understanding of the two villains and their unusual relationship. "Love is a Croc" explores themes of love, acceptance, and the ways in which society often ostracizes those who appear different or have disabilities. It also adds depth to the character of Killer Croc, who is usually portrayed as a one-dimensional, brute-force villain.
