DC: True Power Saiyan by Demon King

The U.S. government’s covert Cadmus section works to limit the influence of metahumans globally, especially Justice League members.

Galatea and the Doomsday clone it produced made it renowned, but what if this division has other dark secrets hidden inside?

They were able to start a new endeavor thanks to an important discovery and a few fortunate circumstances. An enhanced member of one of the greatest warrior species to have ever lived in the fictitious universe who engages in combat, murders, and destroys anyone who stands in his way.

But if someone wakes up in a Saiyan form, they quickly discover they are not in the Dragon Ball reality.
He is an abnormality that shouldn’t exist in a different universe; either he will beat the odds and become something much more incredible, or survival will be his sole objective!
