J. J. Thunder

Jakeem Johnny Thunder (usually called J. J. Thunder) is a fictional character published by DC Comics and a member of the current version of the superhero team the Justice Society of America.

A foul-mouthed African-American boy from Keystone City (home of the original and current versions of the Flash), he came into possession of Johnny Thunder's "genie" Thunderbolt. This was during a Justice League/Justice Society crossover, when the world was being threatened by an evil Thunderbolt. With Captain Marvel's help, J.J. was able to "merge" the two Thunderbolts, with the command for summoning the Thunderbolt being zkl (pronounced "so cool").

Jakeem later, and somewhat reluctantly, joined the Justice Society. Like Johnny before him, he often caused trouble by wishing for things without meaning to, thanks to poorly-worded commands. When Johnny returned, having apparently recovered from Alzheimer's disease as the result of one of Jakeem's wishes, wish, he demanded the Thunderbolt back. However, it turned out that this was actually the villainous Ultra-Humanite, controlling Johnny's body. Jakeem was able to wrest control of the Thunderbolt back, but Johnny lost his life. Jakeem then wished that the Thunderbolt could save Johnny somehow. In desperation, the Thunderbolt merged with Johnny, creating a new being with the memories of both.

Jakeem resents being seen as a kid by the rest of the team, especially Stargirl, although as the closest to his age on the team, he sees her as a friend. Living in Keystone, he has formed a friendship with Bart Allen, the teenaged superhero Kid Flash (formerly known as Impulse).
