In the Ultimate Marvel continuity, Storm is a founding member of the "Ultimate X-Men", created by Mark Millar and Joe Quesada on February 2001. Millar, who wrote for the series until July 2003, established Storm as an illegal immigrant from Morocco who lived in Athens, Texas as a car thief prior joining the X-Men. In contrast to her mainstream counterpart, Ultimate Storm initially has trouble controlling her powers. For example, she once passes out after reluctantly summoning an electrical storm in order to destroy a fleet of Sentinels; her reluctance stemming from a past incident where she nearly electrocuted a playground full of children.
