Ingrid Karlsson was a doctor at Arkham Asylum.
Her kind and caring nature toward the patients gained her the respect of even the Joker. Whenever a patient complained about pain, Ingrid wouldn't stop until the source had been identified and resolved. This behavior led the asylum's director, Jeremiah Arkham, to fall in love with her since she had restored ethics and caregiving to the asylum. They started dating, and eventually, Ingrid and Jeremiah married.
Sometime after this, she became pregnant. Jeremiah wanted her to stop working, but Ingrid wanted to help her patients as much as she could before she went on maternity leave for six months.
One day, when new patients were being transferred to the asylum, a riot broke out. Ingrid went into labor while Batman attempted to stop the potential breakout.
As her husband rushed through the halls to get to her, the patients began to help Ingrid. Clayface morphed himself into a privacy curtain made of mud while Poison Ivy, Harley Quinn, and the Joker helped deliver the baby. Meanwhile, Solomon Grundy fought off any crazed patients to came near. The Joker used his asylum uniform shirt as a swaddle for the baby, and Ingrid had given a healthy delivery to her daughter.
Jeremiah arrived to see this odd, yet happy sight for a moment before one of the new patients threw a batarang at Ingrid, severing her jugular vein and killing her instantly. Jeremiah and the patients looked at the sight in shock and horror. Grundy exploded with rage and crushed the head of the patient who had thrown the batarang. After the riot quieted down, the patients all returned to their cells.Jeremiah kissed Ingrid goodbye, and picked up his newborn daughter, Astrid Arkham.
