After the fans who knew that Quicksilver and The Scarlett Witch are not mutants, theories started spreading as to who they might be. Now all of that can come to a halt.
In the preview for Uncanny Avengers #4 we learn that Wanda and Pietro Maximoff are not the children of Magneto but instead the children of humans Marya and Django Maximoff. They got their powers as many of the Marvel characters have through genetic testing. The preview shows that the Marvel villain High Evolutionary took the twins from their parents and conducted genetic experiments on them. After all the tests concluded they were returned to their parents "disguised as common mutants".
Uncanny Avengers #4 will be in comic book stores on May 13.
