Lex Luthor fanfiction often dives deep into the twisted dynamics between him and Superman, portraying their relationship as a toxic dance of obsession and rivalry. The best works don’t just paint Lex as a one-dimensional villain; they explore his intellectual arrogance, his warped admiration for Superman’s power, and his desperation to prove humanity doesn’t need a god. Some fics frame his hatred as unrequited love turned bitter, where his genius is perpetually overshadowed by Superman’s innate superiority. I’ve read a few where Lex’s schemes are elaborate courtship rituals—destroying Metropolis just to get Superman’s undivided attention. The emotional complexity is chefs-kiss, especially when writers weave in his childhood trauma or his belief that he’s saving humanity from dependency. There’s a fic on AO3 where Lex clones Superman just to have a version of him that’s 'his,' and the psychological horror of that obsession is chilling. The love-hate tension works because it’s never just about power; it’s about validation, ego, and the tragic inevitability of their clash.
Another angle I adore is when fanfiction blurs the line between rivalry and romantic tension. Lex’s dialogue crackles with double entendres, and Superman’s refusal to kill him reads like tragic devotion. Some AU fics reimagine them as lovers in a dystopian world where Lex’s distrust of aliens is justified, making their relationship a heartbreaking ideological divide. The best stories balance Lex’s monstrosity with his humanity—his moments of vulnerability when he realizes Superman sees him as irredeemable. There’s a popular trope where Lex saves Superman’s life in secret, unable to reconcile his hatred with the thought of a world without him. That duality is what makes their dynamic so addictive to read.
