10 Things You Didn’t Know About DC’s Doomsday

7. Booster Gold Came Up With The Name

Unlike many classic villains and heroes, Doomsday never gave himself the name. He was originally known as The Ultimate and rampaged around the universe for thousands of years under that moniker. Then when he found himself on Earth, awake and homicidal, he went on a devastating killing spree ripping through members of the Justice League.

Watching his teammates die, it was Booster Gold, the time traveling hero from the future, who coined the nickname “Doomsday.” It stuck and somehow spread across the universe and now The Ultimate is no more, and Doomsday reigns supreme.
