Born to young unmarried parents, Jakeem Williams was left in the care of his mother's sister. Bitter, he alienated himself from his aunt and others by acting rude and using foul language and generally did poorly in school.

Asking the original Flash, Jay Garrick for his autograph, Jay inadvertently handed him a pink-ink pen, the speedster had received from an aging Johnny Thunder who was now suffering from Alzheimer's.

The pen contained Johnny's thunderbolt, a genie from the Fifth-Dimension named Cei-U, which Jakeem released when Earth was under attack from another sprite from the Fifth-Dimension. The two magical entities merged and are now under the control of Jakeem when he clicks his magic pen.
