Lex Luthor has gone through a lot of changes over the years, morphing from mad scientist to corrupt businessman and even becoming a bona fide hero temporarily. However, one thing that has remained consistent, is his absolute and undying hatred of Superman.
Whether he's motivated by greed, a genuine desire to keep the world safe from Kryptonians or blames the Man of Steel for his hair loss (which was his genuine reason for hating him at one point), Lex is committed to making Superman's life a living hell.
Sometimes his plans involve devious behind the scenes machinations, other times it's a simple case of taking an armour-plated fist to Kal-El's chiseled jaw. Either way, Lex Luthor's schemes have more than earned him a place as Superman's archenemy.
Heck, even when his plans don't directly involve the Big Blue Boy Scout, Lex will usually work in a way to spite his nemesis. Here are the top 10 ways that Lex Luthor has hurt Superman. The acts on this list are so horrible that they're even worse than the time he stole 40 cakes.
That's as many as four tens.
And that's terrible.
10. Founded The Injustice League
As the leader of the Justice League, Superman united his fellow heroes for the noble purpose of saving the world from destruction.
That's not really of interest to Lex Luthor though. All he knows is that if Superman has a nice thing, he wants to take it away.
To that end, Lex Luthor has been the founder of numerous opposite teams to the Justice League, uniting his fellow villains for the less noble purpose of beating up Superman and his friends.
The team started life as the Legion of Doom in the Super Friends cartoon before making the jump to comics. In their first appearance in JLA, Lex named the group the Injustice Gang and recruited villains for each hero on the League, including Joker (Batman), Circe (Wonder Woman) and Mirror Master (Flash).
The gang tried to turn the League against each other so that they would disband, allowing Luthor to set up a new team under his control. The plan failed when Mirror Master betrayed the group after being offered a larger paycheck by the heroes.
Lex and Joker would reform the group later though as the Injustice League, a gigantic gathering of some of DC's biggest villains. Together they were able to take down the Justice League and took them to their headquarters the Hall of Doom (sadly, unlike in the show, it was not located in the awesomely named Slaughter Swamp).
The heroes were eventually able to break free though and capture the villains, an eventuality Luthor had already planned for.
