From mad scientists to alien tyrants, these recurring Superman enemies have helped shape what it means to be a supervillain, and many of them are as popular as ever.
10) Titano

One of the strangest and most obscure Superman villains of all time, Titano is basically King Kong if he could shoot Kryptonite lasers from his eyes. Debuting in 1959, Toto was a chimp who was launched into space in a rocket. During the trip, Toto was bathed in the radiation of Kryptonite and Uranium meteors. Once he returned to Earth, he grew to gigantic proportions and went on a rampage. Since Lois Lane is the only human ever to treat him with kindness, Titano often seeks her out. With his incredible strength and deadly Kryptonite lasers, the giant ape is a threat to Superman. However, despite his enormous size and power, Titano is a minor villain who doesnโt have any significant storylines.
9) Prankster

After the incredible success of the Joker, DC tried to create another comedic villain in 1942, but he just didnโt have the Jokerโs wild charisma. Oswald Loomis, aka the Prankster, was a TV host until his show was cancelled. Enraged over the cancellation, he began setting up elaborate and dangerous pranks to distract people while he committed crimes such as robbing banks. Like the Joker, the Prankster uses a wide assortment of gag-based gadgets to fight the Man of Steel. Still, the Prankster is neither as funny nor as intimidating as the Clown Prince of Crime nor poses a significant threat to Superman. Nowadays, when he does appear, the Prankster is treated as a third-rate joke villain.
8) Toyman

Debuting in 1943, Winslow Schott, aka Toyman, is a more successful and deranged version of the Prankster. After his wife died and his designs for toys were bought and used to create weapons, Toyman went insane and began a life of crime. A brilliant inventor, Toyman creates various toy-based weapons and robots to aid his criminal endeavors, including exploding teddy bears and building-sized mechas. Toyman has also built androids so life-like that they have fooled Superman. Many people have taken on the Toyman moniker over the years, from a founding member of the Legion of Doom to a heroic Japanese child prodigy whoโs an ally of Superman.
7) Ultra-Humanite

First introduced in 1939, Ultra-Humanite was the very first recurring villain in DC Comics history. Ultra-Humanite was initially introduced as a bald mad scientist who wanted to take over the world and had a habit of transplanting his brain into new bodies. However, after falling into obscurity for several decades, Ultra-Humanite reemerged in the 80s with a much more distinct design. The mad scientist had transplanted his brain into the body of an albino gorilla, enabling him to increase his strength dramatically. Unfortunately, despite his role as the first major enemy of the Man of Steel, Ultra-Humanite has been underutilized because Lex Luthor took over his role as Supermanโs genius archenemy.
6) Metallo

Kryptonite is Supermanโs most iconic weakness, and John Corben, aka Metallo, has a heart made of the irradiated space rock. Since Metalloโs introduction in 1959, the most famous version of his origin is that after a fatal accident, he was saved and rebuilt as a killer cyborg powered by Kryptonite. Blaming Superman for his transformation, Metallo uses his mechanical bodyโs ability to generate weapons as well as his Kryptonite heart to their full extent. Almost every time he faces off against Superman, he brings the hero to his knees. Metallo is the second-most-popular villain to wield Kryptonite in DC Comics, ranking only behind Lex Luthor. Over the years, Metallo has been one of Supermanโs most consistent and deadly adversaries.
