Yz (Earth-2: Post-Crisis)

"What the heck are you? I'm your new best friend and you don't even know it!"

- Mike Dugan and Thunderbolt

Thunderbolt is a former member of the Justice Society of America.

Early Life
Thunderbolt was originally from Bahdnesia before his homeland's destruction. Later, Thunderbolt went to the United States and his presence as a "genie" caused a heart attack in an elderly man, sending him to the emergency room.

Johnny Thunder & the Thunderbolt
At some point, Johnny Thunder began using Thunderbolt to fight crime as a member of the Justice Society of America.

On December 24, 2010, Johnny and Thunderbolt fought against the Injustice Society of America. Unfortunately, Johnny passed away after Brainwave murdered him before he made a final wish for Thunderbolt to find a friend. After Johnny's death, Thunderbolt was stored as a pink pen in the Justice Society of America headquarters.

Taken to Blue Valley
When Pat Dugan brought Courtney Whitmore to the Justice Society's headquarters, she attempted to pick up Thunderbolt's pen but was told not to as it was the most dangerous thing there. Courtney later returned to the headquarters and took numerous JSA artefacts, including the Thunderbolt. She later tried to use the Thunderbolt by clicking the pen but nothing happened even after several tries, so she placed it in a pencil holder and left the room.

So Cool!
In summer 2021, Mike Dugan took Thunderbolt and not realize it was not an ordinary pen. He later altered words in Mike's eyes and they appeared as "so cool". Mike quickly tripped over a stone and said the words out loud, releasing Thunderbolt from the pen as he exclaimed in joy. Thunderbolt introduced himself as a member of the JSA and started telling Mike about his past with Johnny.

Thunderbolt and Mike soon walked around and found a little girl being bullied by Mike's classmates. Mike wishes for them to stop. Unfortunately, his wishes were vague and Thunderbolt sent stop signs to land in front of them until they actually stop. Courtney and Yolanda later arrived and brought the two to the Pit Stop.
