Little is known about the first daughter of Magnus save that she is the sister of Quicksilver, the heir to the House of M. The speedster is extremely protective of his sister, and during her rare public appearances he is never away from her side. A non-mutant, Wanda is rarely seen in public. She is, however, constant fodder for the tabloid press, a situation which irks Magnus to no end.
Wanda has children but, outside of the royal family, it is unknown who the father is. Some believe one possible father could be popular television star Simon Williams, known as Wonder Man, but that is merely speculation. Many believe it is because of his daughter's human genes that Magneto has been so merciful to the lesser race that attempted to enslave his people.
