Publication historyEdit

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.[1][2][3]

Fictional character biographyEdit

Yz is a 5th Dimension Jinn 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.[4][5] Later on, Johnny Thunder became aware of Thunderbolt's existence and the summoning word "cei-u."[6]

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.[7]

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.[8]

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 in order 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 loses his life. 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.[9]

In the "DC Rebirth" reboot, it was mentioned that Johnny Thunder lost Thunderbolt after Joseph McCarthy had him reveal his secret.[10]
