Married to Prudence Warren-Wentworth
- "I do not think I will take you up on your offer, Helena. I may need my powers to look after my husband."
Michael and Prudence were to be married, but she called off the wedding the day before, as she did not wish to get married or have children until she had gotten rid of her magic. He attempted to save Prudence from having her powers removed by Helena, and, after her telekinesis saved his life, she chose to keep them, and the two wedded. They had a daughter named Cassandra.
- According to the family tree seen in Pardon My Past, the Charmed Ones' great-great-great-great-great-grandparents were Bartholomew Bowen and Lucille Warren, rather than Michael and Prudence.
Michael Wentworth has appeared in a total of 1 non-canonical novel throughout the franchise.
