Agamemno is a fictional character, a supervillain in the DC Comics universe. He first appeared in Silver Age #1 (July 2000) during the Silver Age event (a series of Silver Age styled one-shots of which he was the chief antagonist). He was created by Mark Waid.

Agamemno is the son of the first sentient being to be created after the Big Bang. His father ruled the universe for eons before being deposed and killed by a group of similar, though younger, cosmic entities. Agememno, his heir, fled and has presumably been on the run from his father's killers ever since, all the while plotting to regain universal domination.

He was an interplanetary conqueror who controlled many worlds; in his search for universal control, he learned of 3 items that would allow him to become all powerful: the Absorbascon (a mind reading device) from Thanagar, a piece of crystal kryptonite, and the central power battery of Oa.

A few years after the formation of the Justice League of America, he learned of their existence from Kanjar Ro. He arrived on Earth and allied with Lex Luthor and several criminals, thus creating the Injustice Gang. These villains were promised control of Earth in exchange for helping Agamemno conquer the universe.

Agamemno used his powers to swap the minds of the JLA with the villains as follows:

The villains succeeded in securing the items Agememno required (despite being driven back into their own bodies) and became omniscient in the process. The villains threatened to destroy the JLA with the knowledge they'd learned about them but were ultimately defeated when the JLA used Robby Reed's H-Dial to become new superheroes of which no one had any knowledge.
