Operation: Rebirth is from the Non MAU videos Ultimate Avengers and Ultimate Avengers II.

Operation: Rebirth, also called Project: Rebirth, was the method that turned meek, little Steve Rogers into the supersoldier Captain America. A version was later used to turn Bruce Banner into Hulk.

Initial TestEdit

World War II broke out and Nazi Germany, led by Adolf Hitler, threatened to take over Europe and all of the world. Steve Rogers wanted to join. However, because of his size he was unfit for duty.

During this time, the United States found out about a Nazi supersoldier named Herr Kleiser. This man was the director of the Nazi's secret Totenkopf Division. To combat this threat, in 1940 the US initiated Operation: Rebirth. Somehow, Steve became involved in the project. He became the first and only human test subject.

He was placed in the glass Rebirth chamber and strapped to an upright table. Scientists monitored while the chamber was filled gas, the super soldier serum. Steve writhed in pain as his bones and muscles expanded. He emerged as a large, muscular man that towered over most others, the peak of human perfection.

However, because of the poor record keeping abilities at the time the secret to the serum was lost. Cap's blood was the only key to unlocking more.

Tries out the new version

Captain America became a legend. Bruce Banner heard about him and wanted to follow in his footsteps. Bruce was commissioned by S.H.I.E.L.D. to build another Rebirth chamber and tried a version of serum he created. However, he became the Hulk and rampaged across New York City. He and Betty Ross continued to recreate Rebirth and the serum without success. When Cap reemerged Bruce took his blood to make another serum. He was briefly able to control Hulk but not for long. Afterwards, S.H.I.E.L.D. presumably gave up trying to recreate it.


Operation/Project: Rebirth was unnamed in both videos. Only the Rebirth chamber was named.
