OMAC is an acronym used by several related concepts in the DC Universe. Originally it was the alias used by Buddy Blank, a corporate nobody working for the Global Peace Agency in the future. Their satellite Brother Eye gave him incredible powers and transformed him into the One-Man Army Corps. During The OMAC Project in the modern era, Checkmate creates an OMAC virus under the leadership of Maxwell Lord; hijacking Batman's Brother Eye technology, they use infected human drones to neutralize superhero threats worldwide. Following the timeline reboot in Flashpoint, the Omactivate! storyline introduces an OMAC named Kevin Kho involved with Project Cadmus and Justice League International. OMAC was created by Jack Kirby, first appearing in OMAC #1 (1974).
