Lark was the Penguin's personal chauffeur and bodyguard.
To keep Harold on their side, Penguin ordered Lark to give him a massage, but she refused as she found Harold repulsive. However, she was convinced when Penguin promised her that she could kill Harold when they no longer needed him. Afterwards, Lark escorted Penguin and Harold to his personal chalet, where Penguin planned to sell Harold's creation to international criminals. When Penguin's plan failed and Batman stopped him, Lark vanished alongside the rest of the criminals who deserted Penguin.
