Originally organized as an aerospace engineering firm, LexCorp has since become one of the world's largest and most diversified multi-national corporations.
Under the management of its founder, president and CEO, Lex Luthor, LexCorp grew and prospered, absorbing scores of smaller businesses in Metropolis until economists once estimated that Luthor employed 2/3rds of Metropolis' eleven million inhabitants.
Through LexCorp, Lex Luthor uses the corporation's limitless resources to finance, support or even create his various plans to feed and further his ambitions whether it is to further a community service project to swing the public's opinion in his favor or to build a new weapon to crush his Kryptonian nemesis; Superman.
- As a supporting Faction member, Villains can gain trust with LexCorp through completing certain missions or collecting Bounties and gain access to rare and powerful items and equipment from LexCorp Vendors.
- Villains can obtain the LexCorp Logo as an Emblem if they have full Trusted renown with the faction.
- While only trusting a scant few people in the world, and regarding fewer of any personal value, one of LexCorp's employees that Luthor seems to trust thoroughly is his Amazonian bodyguard and assistant, Mercy Graves. Although he ultimately considers her, too, to be disposable.
- During the time of U.N. funded Justice League International, Maxwell Lord's ex-wife, Claire Montgomery, created the corporate sponsored team, The Conglomerate, as competition for the Justice League team. Companies that provided sponsorship to the team included American Steel, Dante Foods, Dupree Chemical, Ferris Aircraft, LexCorp, Ovel Oil, Pax Entertainment, Stagg Enterprises and S.T.A.R. Labs. The team has since dissolved.
- LexCorp's first breakaway patent was the "Lex Wing", a military airplane that Lex claimed made him an aeronautical revolutionary on the scale of John Glenn, or Neil Armstrong.
