## Fictional character biography

Yz is a fifth-dimensional genie who resided in a pen that was entrusted to Johnny Thunder on his birthday where the Badhnesians would use it to rule the world. This plan was thwarted when Badhnesia was attacked by a neighboring country. Later on, Johnny Thunder became aware of Thunderbolt's existence and the summoning word "cei-u".
In the early 1950s, Johnny is kidnapped by the Badhnesians with the intention of executing their original world conquest plan. With help from Thunderbolt, Johnny manages to summon Superman and the would-be conquerors' plans are defeated.
Later, Johnny Thunder develops dementia and loses track of the pen in which the Thunderbolt is being stored. The pen eventually ends up in the ownership of Jakeem Thunder.
In a later battle with Solomon Grundy, Jakeem unwittingly cures Johnny Thunder of Alzheimer's thanks to Thunderbolt. However, Johnny immediately falls prey to the Ultra-Humanite, who takes over Johnny's body to command the Thunderbolt's powers. In the "Stealing Thunder" storyline, Jakeem is one of several heroes left free from Ultra-Humanite's control. Eventually Jakeem wrests control of the Thunderbolt back from Ultra-Humanite, but Johnny Thunder is killed. Jakeem then wishes that the Thunderbolt could save Johnny somehow, so the genie chooses to merge with Johnny, creating a new being with the memories of both. He later assumes the name Johnny Thunderbolt.
In the DC Rebirth reboot, it was mentioned that Johnny Thunder lost Thunderbolt after Joseph McCarthy had him reveal his secret.
In Doomsday Clock, Thunderbolt returned when Doctor Manhattan undid the experiment that erased the Justice Society of America and the Legion of Super-Heroes.
Jakeem later encounters the Teen Titans after Thunderbolt's brother Elias summons Johnny Thunderbolt and removes an artifact known as the Stone of Souls from its body, rendering Jakeem powerless. When the Titans nearly die while trying to save Djinn, Jakeem discovers that he possesses some of Johnny Thunderbolt's power, enabling him to save the young heroes. After Elias' defeat, Djinn restores Johnny Thunderbolt and leaves with Jakeem to explore her newfound freedom.
