The Elders of the Universe are a group of supervillains appearing in American comic book published by Marvel Comics. The Collector was the first Elder to appear, and featured in The Avengers #28 (May 1966), but the idea that he was a member of a group known as the Elders was not introduced until The Avengers #174 (Aug. 1978).

The Elders of the Universe are the last survivors of otherwise extinct races. Each discovered that they had potentially infinite lifespans, dependent on maintaining the will to continue living. They are thus known for their personal obsessions (such as collecting, contests of strategy or strength, and various fields of study), each of which is pursued fanatically. While the characters are not truly cosmic entities, all have achieved some cosmic level of power and knowledge related to their particular pursuit. The first encounter with the heroes of Earth occurs when the Collector came to Earth seeking to expand his collection. Later, the Grandmaster created the supervillain team the Squadron Sinister as pawns to battle the champions of the time-traveling Kang the Conqueror, the superhero team the Avengers.

Although thwarted, the Grandmaster and his fellow Elders take an interest in Earth, and the Collector has two separate encounters with the Avengers, the second ending with his murder by the entity Korvac. The Grandmaster also tricks the entity Death into playing a contest—again involving many of Earth's heroes—that he deliberately loses to resurrect the Collector. The Grandmaster usurps control of Death's realm, and after a battle between the Avengers and the Grandmaster's champions—the Legion of the Unliving—is tricked by the Avengers. An angered Death then prevents the Elders from ever entering her realm, which effectively makes them immortal and is the Grandmaster's true goal.

The Elder known as the Champion of the Universe has a brief encounter with many of Earth's strongest heroes and challenged them to a boxing match. While he did have them use his personal gym to prepare, the Champion of the Universe had to disqualify Namor when he refused to stoop to training and Doc Samson, whom the Champion declared to not be a worthy opponent. The day of the boxing match came around as the Champion of the Universe faces off against his opponents. After disqualifying Thor, Hulk, and Wonder Man for different reasons and defeating by knockout Colossus and Sasquatch in hand-to-hand combat, he faces Benjamin Grimm of the Fantastic Four. Eventually realizing that the outmatched Grimm would never submit under any circumstances, the Champion concedes the match and offers Grimm his respect.
