10 Characters Who Have Defeated Darkseid
1. Emperor Joker
Emperor Joker was a nine-part storyline where The Joker acquired the powers of the world bending Mr. Mxyzptlk.
Giving a madman like The Joker the ability to bend every dimension in the universe to his whim is like giving a firearm to a koala bear: it's not going to end well. Even someone as similarly sinister as Darkseid recognized this and sought help to put a stop to Emperor Joker's tirade before he had the chance to seize the Anti-Life Equation.
The Anti-Life Equation was originally a theory created by Darkseid that contained great power he hoped would grant him power over the entire universe. To stop the newly crowned Clown Prince from getting access to it, Darkseid tried to get help from The Quintessence, but before he knew it, he watched Emperor Joker reduce The Quintessence to imbeciles.
Upon realizing he'll never get access to The Anti-Life Equation, Darkseid surrendered himself to The Joker.
He may have not been defeated in a grand slam bang action scene, but seeing the once mighty Darkseid grovel to The Joker is the most humiliating defeat the tyrant has ever succumbed to.
