Mark Mardon escaped from prison and went to his brother for help. When his brother declined and attempted to call the police, Mark used an experimental weapon his brother had invented to kill him. He found that the wand could control the weather and decided to don a costume and become the Weather Wizard. He has recently been seen performing his weather related feats without the use of his wand, though the extent of his power is unknown. He joined The Rogues and has become a primary villain of The Flash.
