Mr.Freeze and Penguin.
Victor Cobblepot was always off-putting because of his strange appearance and harsh demeanor. He spend most of his life down in lab basements doing research on cryo-weaponry, with a fascination of birds as his side hobby (despite being called a "penguin" during childhood). At the company he worked he met the second woman to not care about his appearance, the first being his late mother. Nora could even overlook his strange collection of umbrellas, which to him were symbols of his mother's love who had always tried her best to shield him not only from the harsh weather where they lived, but also the seering eyes of the people around them.
Nora eventually became attracted to Victor because of his great mind, a mind which others higher up in the company would never acknowledge. After the two of them wed, she became ill, and Victor used the company's resources (without permission) to put her in cryo-stasis while he worked on a cure. In a scuffle between the company head and himself, Victor was accidentally shot with one of the cryo-weapons, and was left in a pool of chemicles which forced him to rely on sub-zero temperatures to survive.
Fashioning his umbrellas, his icon of love and protection, into freeze gun tipped weapons, he sought out to kill the company head, but was thwarted by Batman. In a fight between the two, Nora's capsule was broken, and Freeze Penguin vowed for revenge against Batman.
