Eric O'Grady

Eric O'Grady is introduced in The Irredeemable Ant-Man #1 (December 2006) as a low-level S.H.I.E.L.D. agent who discovers and steals the latest Ant-Man suit created by Hank Pym. Presented as a self-serving opportunist, O'Grady uses the suit for personal gain rather than heroism. He appears across Marvel titles—joining teams and initiatives such as the Initiative, Avengers: The Initiative, Thunderbolts and Secret Avengers—until his death in Secret Avengers #23 (April 2012). In the following issue an artificial Life Model Decoy (LMD) is created using his corpse and memories; that LMD later renames itself Black Ant and pursues a more villainous path.

Sources identify O'Grady as a human male of Irish background who initially appears unmasked as a low-level S.H.I.E.L.D. agent. In costume he wears Hank Pym's Ant-Man suit (the specific visual design details are provided in the comics but are not detailed in the supplied notes). After his death an LMD constructed from his corpse (described in-source as created using his body and memories) assumes the Ant-Man persona and later adopts the Black Ant identity; the supplied material does not provide further detailed visual descriptions of the LMD.

O'Grady's capabilities derive primarily from possession and use of Hank Pym's Ant-Man suit—technology in Marvel continuity that grants size-altering functions and suit-based systems; specific suit functions are referenced in sources as the basis for his actions. Behaviorally, O'Grady is characterized by selfishness, voyeurism, theft, and manipulation, repeatedly vowing reform and relapsing. After his death an LMD built from his corpse retains his memories and agency and later becomes the character Black Ant, continuing narrative roles linked to the original.
