how did scarlet witch and quicksilver get powers
Scarlet Witch Depicted as the children of golden age superhero Whizzer earlier on, Scarlet Witch and Quicksilver are later established to be the unknown offspring of supervillain Magneto. Born to Magneto's estranged wife in Transia, Scarlet Witch and her brother are left in the care of their adoptive Romani parents and she is raised as Wanda Maximoff. In a much later retcon it is revealed that Quicksilver and she are not mutants but were kidnapped and used as genetic experimentations by the High Evolutionary then misled to believe Magneto was their father.
Io (mythology) Io was a priestess of the Goddess Hera in Argos,[5][16] whose cult her father Inachus was supposed to have introduced to Argos.[5] Zeus noticed Io, a mortal woman, and lusted after her. In the version of the myth told in Prometheus Bound she initially rejected Zeus' advances, until her father threw her out of his house on the advice of oracles.[17] According to some stories, Zeus then turned Io into a heifer in order to hide her from his wife;[5] others maintain that Hera herself transformed Io.[17][18]
