Ratboy was a runaway deformed teen living underground in Gotham City who developed an obsessive villainous crush on Dana. Due to his deformity, Ratboy was bullied and teased in his childhood, resulting in him running away and finding a home in the sewers in Gotham City and befriended the giant rats that lived there. While living underground, he desired companionship other than his rats and secretly began spying on the people of the surface, specifically Dana Tan. He began to develop an obsession with Dana, believing they were similar to each other, seeing she was being unintentionally neglected by her boyfriend, Terry McGinnis. Believing she would understand and sympathise with him, Ratboy strongly wanted to be with Dana and began leaving her flowers with note, assuring he will be there for her. Eventually, he decided to kidnap her, wishing for them to live together underground. Upon reawakening from her kidnapping, Dana was surprised by her surroundings and officially met Ratboy. During their time together, she learned of his reasons for abducting her, including his troubled past and discovered his real name to be Patrick.
While Dana felt sorry for him upon learning of his abused past and understood his feelings of neglect, she held no desire to remain with him and tried to convince him to allow her to return home. Ratboy instantly refused her request and declared that she belongs with him down in the underground world and assured he will get anything of her desires. Dana grew worried, seeing more of his obsession, but remained calm and tried to trick him to allow her to return to surface, asking for Rino's Chilli. While he agreed, he ordered Dana to remain underground while he gained the chilli himself and warned her before leaving, not to venture away in the sewers, warning her of the dangers. Once he left, Dana began her quest to escape and return to the surface, but despite her efforts, Dana was almost killed by rats until Ratboy returned, thus failing in her attempts to escape.

Hurt by Dana's words, Ratboy loses all his feelings for Dana, now viewing her to be like "the others", revealing Dana isn't the first to be kidnapped by him. Ratboy reveals he has done the same to Dana before, revealing he has kidnapped previous teens in the past and offered them a "home" to escape the surface society and troubles they deal in their lives. However, when they grew angered and upon seeing their refusal to accept him and seeing they viewed him to be a freak, he would have his rats kill them. Now seeing Dana isn't any different from his previous abductions, he orders his rats to kill her, but is saved by the arrival of Batman. Dana and Batman ward off the rats attack and manage to escape, but not before Dana drops a flaming hockey stick and lands on flammable chemicals, causing the sewers to explode along with Ratboy and his pets. Since then, Dana was returned home and reunited with Terry, resuming their relationship and growing more appreciative of having Terry in her life.
