Player Unknown (Earth-1181)

History
"You see my business is simple; I make weapons, I sell them to whoever I want to. And bam, profit. You call me a madman, I call myself an entrepreneur."

-- Player Unknown

Past Life
Before picking up the alias "Player Unknown", Brenden Greene was in the US Army. During deployment, Greene went insane and killed his squad. This caused him to be kicked out of the army and sent to an insane asylum. Three years into his sentence, Brenden Greene escaped the asylum and fled to South Korea. He changed his name to Nathan Klein to put himself under the radar. During his time in South Korea, he picked up the skill of making weapons and recruited people to carry out shipments to China, Russia, and Syria. He gained millions of profit from this business.

Becoming Player Unknown
After years of shipping weapons, Klein went under the alias Player Unknown so that no one would collect personal information. This would lead to him pulling scams and killing clients that displeased him with no consequences. Player Unknown learned about the location of the Tesseract,
