10,000 years ago, a meteorite crashed on Earth. A protohuman Cro-Magnon bathed in its radioactive rays. Naming himself Kru'll the Eternal, he terrorized early man but was opposed by Anthro. Kru'll outlived his people and set out to rule the world. From Aztecs to Romans, Kru'll continued to face a simple problem, he always outlived those he conquered. Over the centuries, he studied sciences and became adept with using technology for his various plans.

Menace of the Conqueror Caveman![]

In modern times, Kru'll learned that a group of scientists discovered the meteorite, that gave him his immortality, in Greenland. Kru'll came up with a plan to influence the final evolution of mankind and create a race of superhumans to be his subjects, using the meteorite. It needed to be reactivated with a concentrated blast of Lutonium. Kru'll was unsuccessful in gathering enough. During an experiment, Batman and Booster Gold burst in and fought him to a standstill. Booster mistakenly revealed his sidekick, Skeets, ran on a Lutonium power cell. Kru'll created a diversion and escaped with the meteorite and Skeets. Batman and Booster Gold later defeated Kru'll at the Natural History Museum. In the aftermath, Kru'll swore revenge against Booster Gold.

The Malicious Mr. Mind![]

Some time later, Kru'll established himself in Fawcett City and became an enemy of the Marvel Family. He later became a member of the Monster Society of Evil.

25th Century[]

In the 25th century, Kru'll is still alive. While at a display, a security guard named Michael Carter, who would become Booster Gold, brushed past him and made him spill his drink. Kru'll was angry at first but then realized who the guard was and was even more angry to the point of attacking him.

Powers and Abilities[]

Due to being exposed to the radiation from a strange meteorite, Kru'll has become blessed with the power of eternal life. He also has great physical strength, owing to his status as a Cro-Magnon, as well as great knowledge on various different sciences.
