Yz is Thunderbolt, the magical companion to Johnny Thunder. It was originally believed that he was a genie from Badhnisia. However, he was later revealed to be a djinn from the 5th Dimension. His magical powers are extremely vast, but he is limited to obeying Thunder's commands. Following Johnny's retirement, he began working with a young boy named Jakeem Thunder. He has been involved with the All-Star Squadron and the Justice Society.
Yz, the Thunderbolt was created by John B. Wentworth and Stan Aschmeier, first appearing in Flash Comics #1 (1940).
