Apollo secretly had an affair between the events of Rocky III and Rocky IV with Adonis Creed's unnamed biological mother. Unfortunately, Apollo died in the ring against Ivan Drago, and Adonis' mother seemingly died in childbirth.
Thirteen years after Apollo's tragic death, Mary Anne decided to pay Adonis a visit in the Los Angeles youth facility. She adopted Adonis and raised him.
In 2015, Mary Anne watched Adonis fight 'Pretty' Ricky Conlan on the television, and was proud of him for becoming the first person to knock Conlan down and go the distance with him.
