Metallo is a name used by multiple supervillains appearing in comic books published by DC Comics, commonly as an adversary of Superman. Metallo is usually depicted as a cyborg with a kryptonite power source in his heart, which he uses as a weapon against Superman. In 2009, Metallo was ranked as IGN's 52nd-greatest comic book villain of all time. Several people at DC have been converted into robots, as depicted in the story. Cyborg, Robotman, and even Cyborg Superman, for example; John Corben, a crook, is one of the most well-known. After a deadly accident mutilates his body beyond repair, Dr. Vale salvages what he can and transplants it into a mechanized body. Vale was scared of Superman and his propensity for destruction, so he created Corben, replete with a Kryptonite power core, to fight the alien.

Vale's orders don't sit well with Metallo, but he inevitably runs with Superman while pursuing his nefarious operations. His life energy is also Superman's death source, which is a lovely irony. He's also changed his appearance on a few occasions, implying that he could appear out of nowhere. He's basically Superman's own Terminator.

Mister Mxyzptlk (Mxy) is a Superman comic book character created by DC Comics. In the classical mythological interpretation, he is frequently depicted as a trickster deity. Mxyzptlk is a reality-warping superhero who enjoys taunting Superman and making life difficult for him. In some media, he has been portrayed as an obvious supervillain, while in others, he has been portrayed as an antihero.

Mr. Mxyzptlk was created by writer Jerry Siegel and artist Ira Yarborough for the story "The Mysterious Mr. Mxyztplk" (the original spelling) in Superman issue 30 (September / October 1944). Due to a publishing lag, the character debuted in writer Whitney Ellsworth's and artist Wayne Boring's Superman daily comic strip.

In most of Mxyzptlk's DC Comics appearances, the only way to stop him is to trick him into speaking or spelling his own name backward (Kltpzyxm kel-tip-zix-um), which will send him back to his fifth-dimensional home and keep him there for at least 90 days. The character's limitation was changed in the 1986 Crisis on Infinite Earths reboot, when Mxyzptlk's condition was changed to leave a new requirement in each narrative, such as having Superman succeed in convincing Mxyzptlk to paint his own face blue.

Bizarro is a supervillain who appears in DC Comics' American comic novels. The character was initially introduced in Superboy issue 68 by writer Otto Binder and illustrator George Papp as a "mirror image" of Superman (1958), but it obviously didn't go well. Much like Frankenstein's monster, he doesn't know the difference between right and wrong. He then rampages across Metropolis in a distorted attempt to emulate Superman's fight for justice.

Bizarro has a lot of tragic potentials. He has no idea what's going on, so it's easy to feel sorry for him when his actions lead him into trouble. On the other hand, when he wanders into antihero territory, he can be rather amusing. This type of screwball team-up gives the long-running plots a new lease on life. Bizarro has appeared in both comic books and graphic novels, as well as various DC Comics-related items like animated and live-action television programs, trading cards, toys, and video games.

Livewire (Leslie Willis) is a supervillain that appears in DC Entertainment's multimedia. The character was created for Superman: The Animated Series and first featured in Superman Adventures issue 5 in March 1997 (based on the animated series). Her debut appearance in a mainstream comic book was in Action Comics issue 835 by DC Comics (March 2006). She was a member of the Superman Revenge Squad as well as the Supermen of America.

Livewire was created by Evan Dorkin and Sarah Dyer for the DCAU. A relentless shock jock thumbing her nose at authority, Leslie Willis suffers an electrical accident that supercharges her in more ways than one. She then abuses her powers for sick kicks, sporting a personality as wild and unpredictable as the bolts she shoots. Her endless energy makes her a joy to watch whenever she shows up, and it's enough to put even Superman on the floor. That's what the Big Blue Boy Scout gets for trying to shut her down.

Alexander "Lex" Luthor is a DC Comics supervillain who appears in American comic books. Jerry Siegel and Joe Shuster invented the character. Lex Luthor first appeared in Action Comics issue 23 in 1986. He has remained Superman's archenemy ever since.

From the 1960s to the early 1980s, Lex Luthor was portrayed as a selfish and egotistical mad scientist. Since the late 1980s, he has been presented as LexCorp's power-crazed CEO. He wants to eliminate Superman from the world, ostensibly because he sees him as a menace to humanity, but in truth, he envies Superman's popularity and power. Given his high profile as a supervillain, however, he has often come into conflict with Batman and other superheroes in the DC Universe.

Lex Luthor is a normal human with no innate superpowers, but he possesses above-average intelligence, an inventive genius, and a strong knowledge of science and technology. He uses his Warsuit on occasion, a mechanized suit of armor that grants him greater strength, flight, superior weaponry, and other skills. While Lex is most often depicted as a supervillain allied with other villains such as Metallo, Parasite, and Bizarro, and frequently leading DC supervillain teams such as the Legion of Doom, he has also been portrayed as an antihero who will team up with Superman and other heroes when the situation demands it. The character was ranked 4th on IGN's list of the Top 100 Comic Book Villains of All Time and as the 8th Greatest Villain by Wizard on its 100 Greatest Villains of All Time list.

Darkseid is a DC Comics supervillain that appears in American comic books. The character was created by writer-artist Jack Kirby and initially appeared in Superman's Pal Jimmy Olsen issue 134 in December 1970, before being officially debuted in the inaugural issue of The Forever People in February 1971. He is portrayed as the tyrant Lord of Apokolips, whose ultimate purpose is to control the multiverse by removing all hope and free will from sentient beings. Darkseid, a New God and one of the most powerful entities in the DC Universe, began as the main antagonist in Jack Kirby's Fourth World epic before becoming one of Superman's greatest foes and the Justice League's archenemy.

IGN named him the 6th Greatest Comic Book Villain of All Time, and Wizard magazine named him the 23rd Greatest Villain of All Time. Darkseid has been adapted from the comics into a variety of media, including Michael Ironside in the DC animation universe, Andre Braugher in Superman/Batman: Apocalypse, and Tony Todd in the DC Animated Movie Universe voicing the character. Ray Porter played the character in Zack Snyder's Justice League, which was released in 2021 as part of the DC Extended Universe.

General Zod is a DC Comics supervillain who frequently appears alongside Superman in his comic novels. Robert Bernstein developed the character, which originally appeared in Adventure Comics issue 283 (April 1961) and was designed by George Papp. As a Kryptonian, he exhibits the same powers and abilities as Superman and is consequently viewed as one of his greatest enemies alongside Lex Luthor, Darkseid and Brainiac.

Zod's appearance in popular culture was characterized by Terence Stamp's portrayal of the character in the films Superman and Superman II, starring Christopher Reeve. With black hair and a goatee beard, the character was eventually reintroduced to the DC Multiverse. Michael Shannon played this character in the DC Extended Universe film Man of Steel.

Brainiac (Vril Dox) is a fictional supervillain who appears in American comic books published by DC Comics. The character was created by Otto Binder and Al Plastino and first appeared in Action Comics issue 242 in July 1958. He is usually depicted as an extraterrestrial android or cyborg who is one of Superman's most vehement foes and a frequent Justice League foe. Brainiac is infamous for diminishing and taking Kandor, Superman's home planet Krypton's capital city, and in some continuity is even responsible for Krypton's extinction.

The name of the character is a combination of the words "brain" and "maniac". IGN listed Brainiac as the 17th Greatest Comic Book Villain of All Time in 2009. He has been voiced by Corey Burton in numerous DC animated universe television episodes, by John Noble in the animated feature Superman: Unbound, and by Jeffrey Combs in the video game Injustice 2. Brainiac has been played by James Marsters on Smallville and Blake Ritson on Krypton in live-action television.

Doomsday is a supervillain who appears in American comic books published by DC Comics, most notably as one of Superman's most dangerous adversaries and as a member of the Justice League. The character was created by writer-artist Dan Jurgens and originally appeared in Superman: The Man of Steel issue 17 (November 1992) before making his first complete appearance in Superman: The Man of Steel issue 18 (December 1992).

On IGN's list of the Top 100 Comic Book Villains of All Time, Doomsday was rated 46. In The Death of Superman tale arc "Doomsday!", he is best recognized for being the only character to kill Superman in combat. He appears as a secondary enemy in the film Batman v Superman: Dawn of Justice, where he was voiced and motion-captured by Robin Atkin Downes.

Parasite is the name of various supervillains who appear in DC Comics' American comic novels. Each form of the figure has the capacity to absorb the victim's life energy, superpowers, and knowledge for a brief period of time. The most frequent visitor is Rudolph "Rudy" Jones, one of Superman's greatest foes and a member of his rogues' gallery. The parasite was named the 61st Greatest Comic Book Villain of All Time by IGN in 2009.

The Rudy Jones version of the Parasite has been heavily adapted from the comics into a variety of media, most notably Superman: The Animated Series and Justice League from the DC Animated Universe. Brendan Fletcher portrayed him in Smallville, a live-action television series. William Mapother portrayed Rudy Jones in the second season of Supergirl and Anthony Konechny portrayed Raymond Jensen in the fourth season, and Rya Kihlstedt portrayed a variation of Alexandra Allston titled Ally Allston in the second season of Superman & Lois.
