# Lizard (character)

The Lizard (Dr. Curtis "Curt" Connors) is a character appearing in American comic books published by Marvel Comics. Created by Stan Lee and Steve Ditko, he first appeared in The Amazing Spider-Man #6 (November 1963) as an enemy of the superhero Spider-Man. While the character has retained this role throughout most of his subsequent appearances, he has also been portrayed as a tragic antihero and occasional ally of Spider-Man. Connors is sometimes an ally of Spider-Man just as himself, and not necessarily as his alter ego.
In the original Earth-616 version of the story, Curt Connors was a geneticist researching the ability of certain reptiles to regrow missing limbs. He developed a lizard DNA-based serum that would allow humans to do the same, and tested it on himself, hoping to regain his missing right arm; instead, he transformed into a feral anthropomorphic lizard. Although Spider-Man was able to undo the transformation, the Lizard remained a part of Connors's subconscious and would resurface time and time again, often retaining Connors's intelligence and attempting to replace mankind with a race of reptilian creatures like himself. Many stories featuring the Lizard deal with the effects he has on Connors's life and psyche since the latter lives in constant fear that the Lizard will one day completely and irreversibly take over his body. Because of this, he works tirelessly to find a permanent cure for his alternate personality, much to the worry of his wife, Martha Connors, and son, Billy, but also standing in contrast to other Spider-Man foes who take pride in their powers and use them irresponsibly.
The character has appeared in numerous Spider-Man adaptations, including films, animated series, and video games. In live-action, Curt Connors was portrayed by Dylan Baker in Spider-Man 2 (2004) and Spider-Man 3 (2007), while Connors / Lizard is portrayed by Rhys Ifans in The Amazing Spider-Man (2012) and the Marvel Cinematic Universe (MCU) film Spider-Man: No Way Home (2021). In 2009, the Lizard was ranked IGN's 62nd Greatest Comic Villain of All Time.

## Publication history

The Lizard first appeared in The Amazing Spider-Man #6 (November 1963), and was created by Stan Lee and Steve Ditko.

## Fictional character biography
### Origin

Curtis "Curt" Connors was born in Coral Gables, Florida. He was a gifted surgeon who enlisted in the U.S. Army. He performed emergency battlefield surgery on wounded GIs. However, his right arm was injured in a wartime blast, resulting in its amputation.
After his return to civilian life as a research technologist, Connors became obsessed with uncovering the secrets of reptilian limb regeneration. Working from his home in the Florida Everglades with the help of war buddy Ted Sallis, he finally developed an experimental serum taken from reptilian DNA. The serum successfully regrew the missing limb of a rabbit, so then Connors chose to test the serum on himself. He ingested the formula and he did indeed grow a new arm.
However, the formula had an unfortunate side effect: Connors was subsequently transformed into a reptilian humanoid monster. Spider-Man discovered this situation during a trip to Florida to investigate newspaper reports of the Lizard after his employer the Daily Bugle challenged him. After discovering the Lizard's true identity and origin, Spider-Man used Connors's notes to create an antidote to restore him to his human form and mentality. Another attempt to develop this serum for safe use again resulted in Connors transforming into the Lizard, but on this occasion, he was saved thanks to his former colleague Professor X and his first team of X-Men, Beast and Angel tracking the Lizard down in the swamps so that the Iceman could send him into hibernation long enough to develop a cure.

### Life in New York

Later, Curt Connors relocated to New York City attending Empire State University. He was able to repay Spider-Man by developing a formula to save May Parker's life after Peter Parker had given his aunt his radioactive blood during a transfusion, unintentionally putting her in mortal peril. It later became clear that the success of Connors's apparent cure from the Lizard persona was short-lived. A repeating pattern soon occurred, with stress or a chemical reaction turning Connors into the Lizard, Spider-Man fighting him, and then forcing him to swallow the antidote to reverse the transformation until the next time. A second personality had formed with the Lizard, one with the familiar goal shared by many villains of taking over the world. The Lizard envisioned a world where all humans had been transformed into (or replaced by) super-reptiles like himself. Despite the Lizard's overall hatred of humans, he was often shown to be unwilling to harm his wife Martha or young son Billy.
As Connors, he aided Spider-Man in defeating the Rhino by developing a formula to dissolve the Rhino's bulletproof hide, but accidentally transformed himself into the Lizard due to exposure to the chemicals needed to create the formula and was restored by Spider-Man. Connors was later abducted and forced to create a rejuvenation serum for Silvermane. However, the stress from this caused Connors to again transform; the Lizard then battled Spider-Man and the Human Torch, and was restored to normal once again by Spider-Man.
During another encounter with Spider-Man after Peter's attempts to remove his powers resulted in him growing four extra arms, a bite from Morbius endowed the Lizard with Connors's personality via the infection of a strange enzyme. Connors then synthesized an antidote for himself and Spider-Man using the Morbius enzyme. Curt Connors later aided Spider-Man, Ka-Zar, and Black Panther against Stegron. After the apparent death of the Jackal, Connors determined that Spider-Man was not a clone. Later, the Lizard battled both Stegron and Spider-Man after Stegron kidnapped Billy Connors. For a time, Peter Parker worked as a teaching assistant to Connors at Empire State University, although Connors had no idea that Peter was Spider-Man. During this time, Spider-Man and Connors dealt with one of Connors's previous experiments in the form of the Iguana.
During the first of the Secret Wars, the Lizard had reverted to his more primitive state and refused to participate on either side of the conflict. Although he was collected by the Beyonder along with other villains, he broke away from the main group after the first battle to settle in a swamp, where he befriended the Wasp, who had helped him treat an injury that he had sustained in the first battle. After the Lizard was blasted by the magic of the Enchantress, he reverted to human form.
After Connors's return from this event, his wife Martha, unable to take it anymore since Connors had said that he had been permanently cured, only to disappear for many days and then return home in tattered clothing with no plausible explanation as to where he had been, took their son Billy and separated from Curt. The Lizard had been affected by inter-dimensional teleportation so that Connors's mind presided over the Lizard, and he battled the Owl alongside Spider-Man. However, mystical activity during Inferno once again brought the Lizard's bestial nature to the fore, and Spider-Man cured him again.

### The 1990s through 2007: Civil War

Connors then tried to straighten out his life and control the Lizard, with some degree of success. This ended when the villainess Calypso used her voodoo magic to take control of the Lizard (during the Torment storyline) for her purposes, reducing him to a mindless, savage state. After a series of bloody battles, the Lizard and Calypso were defeated by Spider-Man, and Spider-Man assumed that he perished under Calypso's spell. Connors once again gained control of the Lizard's mind and body, although it was very weak. Curt carried out a plan to cure himself temporarily, after which he voluntarily submitted to incarceration in the supervillain prison the Vault. When Calypso forces the transformation and attempted to control the Lizard once again, the creature killed her and escaped from the Vault. After this escape, the Lizard falls into a quicksand pit during a battle in the Everglades with Spider-Man and the bounty hunter Warrant and was believed to have died.
Later, a huge bestial Lizard appeared, shortly after Connors was called in to investigate Peter Parker's sudden sickness (the result of Peter's recently lost spider-powers returning). Spider-Man (Ben Reilly) realized that not only had the Lizard survived, but revealed later his new monstrous transformation seemed to be permanent and the personality of Curt Connors appeared completely lost. However, when this savage mindless Lizard later unexpectedly encountered Dr. Connors himself while Connors was helping Peter, Curt became the true Lizard once again and saved his family by killing the "Lizard-clone." It was revealed that the Lizard clone was a scientific accident resulting from an experimental formula being tested on a piece of the original Lizard's tail, which had then grown into a fully formed second creature.
Although reunited after Curt's apparent death, Martha and Billy were diagnosed with cancer after being exposed to carcinogens from living near an industrial lab in Florida. Spider-Man assisted Curt in successfully forcing Monnano, the lab's owner, to admit culpability, but Martha died from her cancer. Billy recovered but remained bitter towards his father. Curt's guilt and internalized anger led him to become the Lizard once again, and once human, Curt attempted a bank robbery so that he would be sent to prison. After a short-lived term, Connors was released and changed into the Lizard once more, this time due to a scheme by Norman Osborn to form the Sinister Twelve to kill Spider-Man. The Sinister Twelve were defeated and captured by the combined forces of Daredevil, the Fantastic Four, and the Avengers.
The Lizard resurfaced to face Spider-Man with the aid of Billy Connors, who was changed into an adolescent Lizard by his father. Both the Lizard and his son were captured and reverted. Billy's transformational ability has been ignored since. A new Sinister Six team, including new member the Lizard, appeared during the superhero Civil War, but it was stopped by Captain America and his Secret Avengers.
Post-Civil War, Curt Connors aided Spider-Man in developing a cure for the victims of Mister Hyde who were mutated with unstable versions of Spider-Man's powers. Dr. Connors has also monitored the progress of the hero Komodo, a female grad student who stole a sample of Connors's Lizard formula. She modified the formula for her own DNA to grow back her missing legs and to give herself reptilian powers.

### Brand New Day (2008) and beyond

Doctor Curt Connors appeared in the 2008 Brand New Day storyline, where he experimented with animal stem cells as well as aiding forensic specialist Carlie Cooper. The third Freak mistook Connors's stem cells experiment for drugs. Connors helped Spider-Man defeat the Freak during their second encounter.
During the events of The Gauntlet, Curt Connors was working for the pharmaceutical company Phelcorp under executive Brian King. Connors had lost custody of his son, Billy, and started hearing the voice of the Lizard persona goading him to let it have control. After Connors's assistant slept with King, Connors began struggling to contain the Lizard, ultimately losing control when King stopped him from taking a dose of his Lizard suppressing antidote. When Connors changed into the Lizard, he devoured King as a rival male. Knowing that the Lizard has targeted Connors's son Billy in the past, Peter Parker decides to protect Billy and swings to his foster parents' home. There, he finds that Billy was kidnapped and his new parents are being held hostage by Ana Kravinoff. Ana had left Billy in an alley, where the Lizard ate him, the trauma of which functionally destroyed the Connors persona. No longer having Connors internally warring with the Lizard, he enters a metamorphosis, emerging in a new form, sporting a leaner physique, long brown spikes on its head, spikes on its right forearm, human intelligence, and the ability to telepathically communicate with the underdeveloped "lizard hindbrain" portion of human brains. He demonstrated the latter ability by triggering the instinctual prey response of Spider-man's lizard brain, temporarily overwhelming the superhero and causing him to flee in terror. Back on the street, the Lizard mentally triggered the lizard portion of numerous people's brains, causing them to behave in savage and often violent ways. Away from the Lizard, Spider-Man ingested Connors's Lizard suppressant formula, temporarily making him immune to the Lizard's mind controlling powers. Spider-Man then injected the Lizard with some of the formula, hoping that Connors would be able to resume control. Although Connors is no longer present, the formula does increase the prominence of the Lizard's "monkey brain", aka the human intelligence portion of its brain. This causes him to consider (and regret) some of his actions, including killing Billy and trying to make people embrace their lizard instincts. Reverting most of the people he had affected with his telepathic powers, The Lizard disappeared into the sewers after the fight.
During the Origin of the Species, the Lizard joined Doctor Octopus's supervillain team and stole Menace's baby. As Doctor Octopus and Spider-Man fought within the Lizard's hideout, the Lizard at first attacked Spider-Man, but then gladly returned the baby. He revealed that he already took a blood sample from the baby and found out that Norman Osborn was not the father; therefore, the baby was useless to him and all of the villains. Doctor Octopus, angry about the Lizard's hypnotism obstructing his intellect, attacked him while Spider-Man escaped with the baby. Both Doctor Octopus and the Lizard survived this fight.
A short time later, while investigating kidnappings in New York, the X-Men found themselves working with Spider-Man after they discovered that the abductor is the Lizard, who had been turning the victims into lizard people, while maintaining his control over the city's reptile population. The X-Men and Spider-Man discovered that the Lizard was being used by the Dark Beast, who had given the Lizard his 'reptilian shift' abilities by using a machine. During the battle, the Lizard shifted Gambit, Storm, and Wolverine into lizard people. Emma Frost and Spider-Man escaped the machine's effects, released the Lizard and used him to defeat the Dark Beast, who was arrested while the Lizard escaped.
Sometime later, Michael Morbius discovered that the Lizard had used DNA samples from Billy Connors' corpse to restore Curt Connors to humanity. Unfortunately, the Lizard's psyche was still present and was pretending to be Connors so that he would be left alone. The Lizard/Connors released blood into the air supply to provoke Morbius into attacking the other lab workers. The Lizard/Connors then tried to recreate his original Lizard formula so that he could change again, but Morbius' cure instead only allowed him to regrow his missing arm. The Lizard/Connors then injected Max Modell and other Horizon Lab personnel with his formula to discover how to "cure" himself. Attempting to appear to be the "normal" Connors, the Lizard/Connors cut off his regrown limb, but the Lizard began to appreciate human life, to the point that when he found the correct Lizard serum, he contemplated remaining human, but he took the cure when Spider-Man arrived and threatened him with custody. This resulted in yet another streamlined, new form. A new cure was developed for the lab employees that he had changed, but this formula failed on the Lizard's new form; he was instead knocked out and taken to the Raft. Visiting him in the Raft, Spider-Man was unaware that the serum had restored Connors' psyche and Connors remained in prison willingly, as he felt that he deserved it for his actions as the Lizard.
During the "Dying Wish" storyline, Peter Parker (whose mind was trapped within Doctor Octopus' dying body) was freed from the Raft by the Trapster, Hydro-Man, and the Scorpion. The Trapster offered to free the Lizard, but Connors declined. When Morbius the Living Vampire managed to escape his cell, the Lizard pointed out that he still had nowhere to go. For unknown reasons, Morbius then freed the Lizard.
The Lizard was then seen back in his cell, being one of the few inmates left to be transported out of the decommissioned Raft. When Alistair Smythe attempted an escape from the Raft, he temporarily shut down the Raft's power, letting the Lizard out of his cell. The Lizard protected J. Jonah Jameson from the Scorpion, revealing that he had the mind of Curt Connors, and that he "will never let the monsters win again." Jameson defended the Lizard from the Raft's warden, calling him a hero, and protesting the use of a restraining device, though the Lizard himself preferred to be cautious. During Smythe's final escape attempt, the Lizard was impaled through the shoulder, but survived.
As part of the "All-New, All-Different Marvel" as part of the lead-up to the "Dead No More: The Clone Conspiracy" storyline, the Lizard was shown at the Andry Corrections Facility. He was escorted to the visitor's room and his restraints were removed. After the guards left the visitor's room, the Lizard met the mysterious red-suited man where he claimed to have met Curt Connors before. The Lizard detected familiar scents accompanying the man, scents that could not be there, and warned him not to toy with the Lizard. The red-suited man replied that he was not the Lizard; inside he was Curt Connors, a model prisoner who saved Mayor J. Jonah Jameson and various civilians before and was trapped in a monster's body. The Lizard lashed out at him, demanding to know how can the people that he was smelling be there. The man said that the Lizard had abilities that he could use and if he escaped and joined him, he could give him anything. He snapped his fingers and Martha Connors and Billy Connors stepped forward, where they were somehow alive. The red-suited man asked if they have a deal. The Lizard tearfully accepted his deal. It was revealed that the revived Martha Connors and Billy Connors were clones that the red-suited man had gathered to grow clones with false memories that span all the way to their deaths. The Lizard and a depowered Electro were later sprung from Andry Corrections Facility by the Rhino on the red-suited man's behalf. The Lizard worked with the Jackal on a procedure that would repower Electro. The first time it was interrupted, the Lizard was present when the Jackal summoned a somehow-revived Francine appears to convince Maxwell to go through with it. The second time it was interrupted was when Martha Connors informed everyone present about a fire in Edmond, Oklahoma that neither of them was responsible for. While escaping from New U Technologies, Spider-Man and Spider-Woman of Earth-65 quickly incapacitate the Lizard. When Doctor Octopus pulled a switch which activated the Carrion Virus in all of the clones and caused them to start rapidly decaying, the Lizard saw that Martha Connors and Billy Connors were affected. During the ensuing battle, the Lizard escaped with Martha and Billy as he vowed to find a way to keep them from dying. In the sewers of San Francisco, the Lizard saved Martha and Billy Connors from the Carrion Virus by injecting them with the Lizard formula, turning his wife and son into lizard people like himself.
Connors was later shown having returned to Empire State University, now using a special chip implanted in the back of his neck to control his Lizard persona, with the chip acting as an inhibitor that stopped him from attacking humans. Teaching once again, Connors offered to support Peter Parker's efforts to re-apply for his doctorate after he was academically disgraced by accusations of plagiarism of Otto Octavius' thesis since Doctor Octopus' mind was in Peter's body at the time. The inhibitor proved to be a disadvantage when Connors' class was attacked by the Taskmaster and the Black Ant and he could not defend himself.
When Connors was captured by Kraven the Hunter as part of his organized hunt for various animal-themed villains, he was locked in a cell with Spider-Man while the two of them watched live footage of the Black Cat and the Lizard-esque Billy Connors being hunted, with Billy admitting that he actually remembers his original death. Faced with a threat to his son, Connors asked Spider-Man to tear out the inhibitor chip so that he could rescue his son, despite the risk of this action leaving Connors paralyzed at best, the two unaware that Kraven had set the situation up precisely to force Spider-Man into a position where he would become the ruthless warrior that Kraven believes that he 'should' be. However, Connors managed to maintain control and retrieve Billy without killing anyone.
In a prelude to the "Sinister War" storyline, Doctor Octopus coerced Curt Connors into using the Isotope Genome Accelerator on himself which separates him from his Lizard side. Kindred then completed the Sinister Six by having Mysterio join him as Kindred notes that his endgame with Spider-Man is approaching. Spider-Man found Connors in his wrecked lab as he was informed on what happened. Peter then took Connors home in the sewer to recover with his family. Spider-Man suspects that Doctor Octopus is forming his latest incarnation of the Sinister Six. Lizard's Isotope Genome Accelerator duplicate and the rest of the Sinister Six proceeded to compete with the other villains that Kindred enlisted to take out Spider-Man. Doctor Octopus managed to have all the villains subdued when he hacked into Black Ant's helmet by changing the setting to centipedes which affected the centipedes in every villains' head.
During the "Beyond" storyline, Maxine Danger of the Beyond Corporation sent Misty Knight and Colleen Wing into the sewers where they apprehended Lizard's Isotope Genome Accelerator duplicate. Upon being taken to Beyond Corporation's secret facility on Staten Island, the genetic template of Lizard's Isotope Genome Accelerator duplicate was combined with the genetic template of Morbius the Living Vampire to create a binary clone called Creature Z which looks like a white version of Lizard with the fangs and wings of a vampire bat. After the facility was destroyed by Monica Rambeau and the Machine Man Imposter and Creature Z was overloaded with the blood it sucked out, Lizard's Isotope Genome Accelerator duplicate was rescued by Morbius. As Morbius planned to work with him in curing their conditions, he is unaware that the Lizard he rescued is an Istopte Genome accelerator duplicate.
During the "Blood Hunt" storyline, Spider-Man was fighting some vampires until he ran into Lizard's Isotope Genome Accelerator duplicate. Lizard's Isotope Genome Accelerator duplicate was revealed to be recruited by Misty Knight to help look for Morbius the Living Vampire and Colleen Wing. They fought against the vampires and found a computer in a fake church established by the Beyond Corporation.

## Powers and abilities

Dr. Curtis Connors gave himself superhuman powers as a result of exposure to the Lizard Formula, allowing him to transform into the Lizard. In human form, he has none of his superhuman powers, but he is highly intelligent and a well known scientist in fields of genetics, physics, biochemistry and herpetology.
When Connors is transformed into the Lizard, his strength is increased to superhuman levels. Likewise, his speed, stamina, agility, and reflexes are also raised to a level equivalent to that of Spider-Man. He can also scale walls using a combination of his sharp claws and micro-scales on his hands and feet that create molecular friction like those of a gecko. He is highly resistant to injury due to his thick scaly hide, allowing him to resist punctures and lacerations from ordinary weapons and lower-caliber firearms. In addition, the Lizard has highly enhanced healing abilities which allow him to quickly recover from grievous wounds, including regenerating lost limbs. He also has a powerful tail which he can whip at high speeds. The Lizard has razor-sharp teeth set in muscular jaws that can deal a lethal bite (the latter is established in the Lizard's later appearances; in his earlier appearances he seems to have no teeth at all). Like a reptile, he has cold-blooded characteristics and is therefore sensitive to drops in temperature; a sufficiently cold environment will cause his metabolism to slow drastically and become dormant if he is exposed to cold temperatures for too long.
The Lizard can mentally communicate and command all reptiles within a mile of himself via limited telepathy. He has also on at least one occasion secreted powerful pheromones which caused nearby humans to behave violently. Post-Brand New Day, a further enhancement of his telepathy granted him the power of telepathically compelling humans to act out their primal urges, by suppressing emotional control in their amygdala (the "lizard brain").
Based on various physiological and environmental factors, the Lizard's intelligence can range from bestial and animalistic to normal human intelligence. The Lizard personality has most often manifested with human intelligence, capable of speech and higher reasoning, although some versions have been more feral than others. During the "Secret Wars" in particular, he appeared less ruthless than his normal portrayal, showing concern for Volcana and the Wasp after they showed him kindness despite his usual disdain for humans. However, even when operating at the level of a human, the Lizard is rarely as intelligent as Dr. Connors, showing on many occasions an inability to understand his human self's work and use it to further his own ends despite his best efforts.
The Lizard has apparently "destroyed" the Curt Connors persona, but has subsequently begun to display some of Connors's human emotions. In contrast to his previously feral nature, he has also shown sufficient intellectual capabilities to replicate Connors' work for himself, although he is still hampered by his inability to fully comprehend human emotions.

## Continuity

In a 2004 story arc entitled Lizard's Tale, written by Paul Jenkins in the Spectacular Spider-Man comic book, it was revealed that the Lizard persona was not a separate personality from Dr. Connors after all — Curt had been consciously controlling his reptilian alter ego all along. Furthermore, Connors was shown to know that Peter Parker was Spider-Man, despite the discovery of the secret identity never being explained or depicted. The story ended with Dr. Connors deliberately getting himself sent to prison and hoping the Lizard would not be unleashed again. The Lizard's next appearance after this was as a member of the Sinister Twelve, where he showed no indication of being controlled by the mind of Dr. Connors. Although the idea of Connors controlling the Lizard was subsequently ignored, when the Lizard's mind was briefly trapped in Connors' human form, he attempted to mutate the staff of Horizon Labs into lizard people like himself, with none of the other lizards demonstrating the same hostility to humans as the Lizard, prompting Spider-Man to speculate that the Lizard's anti-human traits came from Connors' anger at the world for his lost arm and family rather than the Lizard being completely separate from Connors.
Another continuity-related issue involves Connors' son Billy. Unlike many other Marvel Comics children, he has not appreciably grown up since the comics' stories of the 1960s. Billy's visible age also seems to waver back and forth between approximately eight and 13 years old, depending on the particular comic artist drawing the character.

Additionally, he does not wear clothes and has a less pronounced snout, giving him a more humanoid appearance.
** Connors first appears in the Sony film The Amazing Spider-Man (2012). Peter Parker finds Richard's notes and visits Connors to continue what he and Richard started. The two successfully formulate a serum together, which Connors injects himself with after being fired from Oscorp for refusing to rush into human trials. The serum regenerates Connors' lost arm, but eventually mutates him into the Lizard, who goes on a rampage until Spider-Man intervenes. Escaping into the sewer, he reverts to his human self, but the effects of the serum makes him obsessed with his abilities. He builds a makeshift off-site lab while the Lizard persona further corrupts his mind by manipulating him to experiment on himself further. The Lizard discovers Spider-Man's secret identity, develops a mind of his own, and asserts himself as the dominant personality while seeking to mutate all of New York into lizards like himself. However, Spider-Man foils his plan with Captain George Stacy's help and cures him. With the Lizard's personality gone and his sanity restored, Connors surrenders to the authorities. In the film's mid-credits scene, Connors is remanded to Beloit Psychiatric Hospital, where he speaks with the Gentleman regarding the Parkers' knowledge of him.
** Ifans reprised his role in the Marvel Cinematic Universe (MCU) film Spider-Man: No Way Home (2021). Sometime after learning Peter's secret identity, Connors is transported to an alternate universe (MCU), where he is found and imprisoned by Doctor Strange alongside other alternate universe-displaced supervillains. He encounters the MCU's version of Peter Parker, who offers to cure them and avert their original fates upon returning to their respective universes. Skeptical of this for fear of unforeseen consequences, Connors joins Green Goblin in fighting back. The former later joins Sandman and Electro in fighting three Spider-Men before he is eventually defeated and cured by the second Parker. After reverting to his human form, Strange returns Connors and the other displaced individuals to their respective home universes.
