How has lex luthor s character evolved in different comic runs?

Lex Luthor's character has undergone substantial evolution since his 1940 debut. In his earliest appearances, Luthor was primarily a scientist who opposed Superman for personal gain, often portrayed as a reformed villain who could work with heroes. The 1980s 'Man of Steel' reboot by John Byrne reimagined Luthor as a more complex figure - a brilliant business magnate whose animosity toward Superman stemmed from philosophical differences about humanity's future rather than simple criminal motives. The 'Lex Luthor: Man of Steel' run by Dan Jurgens in the 1990s deepened his characterization as a calculating mastermind who genuinely believes his actions serve humanity's best interests. More recent interpretations, such as those in 'All-Star Superman' by Grant Morrison and 'Superman: Prime' by Dan Abnett, have presented Luthor as potentially redeemable, showing moments where his intellect and concern for humanity could lead to heroic actions if guided differently. The character's relationship with Superman has shifted from antagonist to sometimes anti-hero, with various runs exploring whether their conflict is purely ideological or rooted in deeper personal connections.
