Ocky

 is Aunt Clara's boyfriend. He lives in a haunted castle in England.

Ocky left Aunt Clara for a younger witch. Bereft, Clara volunteered to babysit Tabatha when Darrin and Samantha went out to a business dinner. When she accidentally caused the lights across the entire Eastern Seaboard to go out due to a miscalculated spell, she called Ocky to help. Meanwhile, he had left the young witch because she was only interested in what he could do for her.

Although his own powers were starting to wane, he tried to help Clara fix the problem. However, he was only able to restore the electricity at the Stephenses' home, and only then with his arms stretched up above his head.

In order to leave the house "unnoticed" after Darrin, Samantha, Larry and a client arrived, he became invisible, except for his shoes, and walked out of the house.
