Jakeem Thunder (Jakeem Johnny Williams), initially called J.J. Thunder, is a fictional character in the DC Comics Universe, a member of the superhero team the Justice Society of America. Jakeem first appeared in Flash (vol. 2) #134 (February 1998), and was created by Grant Morrison, Mark Millar and Paul Ryan.

Jakeem Johnny Williams is a precocious teenager from Keystone City (home of the original and current versions of the Flash). Jakeem's mother left his father while she was still pregnant with the boy and he was orphaned when his mother died of cancer. His aunt Lashawn was then granted custody and his father, Phil, never knew (and still does not know) about his birth. Jakeem became a self-reliant latchkey kid who grew up on the streets and adopted a tough, foul-mouthed attitude in order to survive.

When Johnny Thunder began to lose control over his "genie" Thunderbolt, because of his declining mental health, he put the genie inside an ink pen. Without knowing its danger, Jay Garrick gave the pen to Jakeem.

During a Justice League/Justice Society crossover, when the world was being threatened by an evil Thunderbolt, Jakeem soon discovered that the Thunderbolt actually came from the Fifth Dimension and is controlled by speaking its name (Yz) backwards ("Say You"). Jakeem worked with a small group of JSA members, as they attempted to stay alive while Yz and blue genie named Lkz battled throughout space. Jakeem even tried to punch out Qwsp, a third genie that came to threaten the group.

Jakeem Thunder has not been a contender in any CBUB matches.
