Publication history
Thunderbolt (Yz) first appeared in Flash Comics #1, published with a cover date of January 1940, and was created by John Wentworth and Stan Aschmeier.

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.

During Johnny Thunder's time with the Justice Society of America, his control over Thunderbolt was weakening due to a spell cast by Badhnesian priests.

When Johnny Thunder started suffering from symptoms of Alzheimer's disease, he loses track of a pen in which the Thunderbolt is being stored. The pen eventually ends up in the ownership of a young African American boy named Jakeem Williams, who takes up the name Johnny Jakeem Thunder or 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 the Watchmen sequel Doomsday Clock, Thunderbolt returned when Doctor Manhattan undid the experiment that erased the Justice Society of America and the Legion of Super-Heroes. He was once again merged with Johnny Thunder to become Johnny Thunderbolt.

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.

During The New Golden Age, Thunderbolt was with Johnny Thunder in 1940 when a Huntress from a possible future ended up sent back to their time. As Huntress meets the Justice Society of America, Thunderbolt notes that he doesn't recall meeting anyone from the future. Johnny Thunder reminds him that they met Legionnaire. As Doctor Fate tries to read Huntress' mind about the threat in her future, Thunderbolt was among those knocked down by the magical feedback.

In a flashback to the Summer of 1940, Thunderbolt was with the Justice Society when they arrive to recruit Sandman.
