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

Yz, better known as Thunderbolt, is a former member of the Justice Society of America.

Early Life
Yz was originally from Bahdnesia before his homeland's destruction. Later, he 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, Yz started using the alias "Thunderbolt" and worked alongside Johnny Thunder to fight crime as members of the Justice Society of America.

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

Taken to Blue Valley
Ten years later, when Pat Dugan brought Courtney Whitmore to the Justice Society's headquarters, the latter attempted to pick up Thunderbolt but was told not to as it was the most dangerous thing in the room. Whitmore later stole multiple gadgets and suits from the building, including the Thunderbolt, Hourman Suit, Doctor Mid-Nite Suit, Starheart Lantern, and Wildcat Suit. 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 failed to realize that it was not an ordinary pen. He later altered words in Dugan's eyes, and they appeared as "so cool". Dugan 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 Justice Society and started telling Dugan about his past with Thunder.

Thunderbolt and Dugan soon walked around and found a little girl being bullied by Dugan's classmates. Dugan 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. Whitmore and Yolanda Montez later arrived and brought the two to the Pit Stop.
