Info Madelyne Pryor:
Madelyne Pryor (aka Goblin Queen) is a fictional character in the Marvel Comics universe. She is currently the leader of the Sisterhood of Mutants and looking for a new body. As the love interest and first wife of X-Men leader Cyclops/Scott Summers, she became a long-standing member of the X-Men supporting cast; until a series of traumas — being abandoned by her husband, losing her infant son, and discovering that she was created by Mister Sinister, and that she is the clone of Jean Grey. — eventually led to her being manipulated into becoming a supervillain. She has a son with Cyclops, Nathan Christopher Charles Summers, who grows up in a future timeline to later return as Cable.

Madelyne's biography has been rendered particularly complicated because of the many retcons involved in the publication history of both her character and that of Jean Grey.
