Charles Van Dahl was the son of Grace Van Dahl, brother of Sasha Van Dahl, stepson of Elijah Van Dahl, and stepbrother of Oswald Cobblepot. He had a sweet streak not shared by his conniving sister and mother.
Charles and his sister, Sasha, grew up poor and abused by their father. Their mother worked as a waitress at a diner where she met Elijah. Grace, sensing an opportunity for social climb, grew close to Elijah and he offered her and her children sanctuary at his estate. They later married, making Charles heir to Elijah's massive fortune and catapulting him into a life of privilege.
Meeting Oswald Cobblepot
During a visit to the Gotham City cemetary, Elijah met Oswald Cobblepot and discovered that he was his son from a previous relationship. Elijah took Oswald home and introduced him to his new family, declaring over dinner that Oswald was his only biological son. Grace, Sasha, and Charles tried to force Oswald away by outing him as a criminal, but Elijah vouched for him, believing he had changed. Sasha tried to seduce Oswald and when she failed, Charles volenteered to try, implying he is gay or bisexual. When Elijah's heart condition worsened and he seemed inclined to include Oswald in his will, Charles was present when Grace and Sasha conspired to poison Oswald. Instead, Elijah drank the poison and died. 
After Elijah's death, Grace and Charles turned on Oswald and made him their servant. Grace and Sasha insulted his cooking, though Charles seemed to enjoy it. Their constant bullying -with the combenation of Oswald finding out Grace Van Dahl "murdered" his father- eventually broke through Oswald's Arkham conditioning, causing him to snap and kill Charles and Sasha. He cooked them into pies which he served to Grace before killing her, too.
