In the future, Jane Q-X 3 Gem, the Magician from Mars, is born to a Martian father, Jarl 6EM35, and a Earthling mother, Jane Faro. When she was a baby, she was accidently exposed to "cathode" radiation, which is deadly to humans but which Martians are naturally immune to. Because she was a hybrid of the two, the radiation had an unexpected effect of boosting her brain power to the point where she was capable of changing reality with a thought.
Her powers developed as she grows. By age six, she could "wish" things like ice cream cones into existence and levitate things through the air. At 16 years old, she lost both of her parents and was raised by her Aunt Vanza, who refuses to allow the girl to travel to Earth. Eventually, she found life on Mars too boring, so she escaped from the "Supersteel Room" prison her aunt locked her in and took passage on a ship to Earth. There, she decided to use her reality-warping abilities to fight evil and oppression. Eventually, she came head-to-head with the Hood, leader of an evil organization with the goal of "Universal Domination." The Hood is later revealed to be her aunt.
