|Dr. Henry Jekyll or Mr. Edward Hyde|
|First appearance||Strange Case of Dr Jekyll and Mr Hyde|
|Created by||Robert Louis Stevenson|
|Portrayed by||King Baggot|
Philip Van Zandt
|Alias||Edward Hyde (or Hyde or Mr. Hyde)|
Dr. Henry Jekyll, nicknamed in some copies of the story as Harry Jekyll, and his alter ego, Mr. Edward Hyde, is the central character of Robert Louis Stevenson's 1886 novella Strange Case of Dr Jekyll and Mr Hyde. In the story, he is a good friend of main protagonist Gabriel John Utterson.
Based in Soho in the West End of London, Jekyll is a kind and respected English doctor who has repressed evil urges inside of him. In an attempt to hide this, he develops a type of serum that he believes will effectively compartmentalize his dark side. Instead, Jekyll transforms into Edward Hyde, the physical and mental manifestation of his evil personality. This process happens more regularly until Jekyll becomes unable to control when the transformations occur. Dr. Jekyll roams Soho as Mr. Hyde, and Mr. Hyde inhabits Leicester Square as both himself and Dr. Jekyll.
Fictional character biography
Dr. Henry Jekyll is a doctor based in Soho who feels that he is battling between the benevolence and malevolence within himself. He spends his life trying to repress evil urges that are not fitting for a man of his stature. Jekyll develops a serum in an attempt to mask this hidden evil. However, in doing so, Jekyll transforms into a hideous creature, who appears a lot younger than he usually does. Jekyll decides to take advantage of this, naming this transformation of his "Edward Hyde", and uses his new persona to act out his hidden desires free of consequences while keeping his social status as Jekyll. As time goes by, Hyde grows in power and eventually manifests whenever Henry Jekyll shows signs of physical or moral weakness, no longer needing the serum to transform.
Stevenson never says exactly what Hyde does, generally saying that it is something of an evil and lustful nature. Thus, in the context of the times, it is abhorrent to Victorian religious morality. Hyde may have been reeling in activities such as engaging with prostitutes or buggery. However, it is Hyde's violent activities that seem to give him the most thrills, driving him to attack and murder Sir Danvers Carew without apparent reason, making him a hunted outlaw throughout England. Carew was a client of Gabriel Utterson, Jekyll's lawyer and friend, who is concerned by Hyde's history of violence and the fact that Jekyll changed his will, leaving everything to Hyde. Dr. Hastie Lanyon, a mutual acquaintance of Jekyll and Utterson, dies of shock after receiving information relating to Jekyll. Before his death, Lanyon gives Utterson a letter to be opened after Jekyll's death or disappearance.
When Jekyll refuses to leave his lab for weeks, Utterson and Jekyll's butler Mr. Poole break into the lab. Inside, they find the body of Hyde wearing Jekyll's clothes and apparently dead from suicide. They find also a letter from Jekyll to Utterson promising to explain the entire mystery. Utterson takes the document home where he first reads Lanyon's letter and then Jekyll's. The first reveals that Lanyon's deterioration and eventual death resulted from seeing Hyde drinking a serum or potion and subsequently turning into Jekyll. The second letter explains that Jekyll, having previously indulged unstated vices (and with it the fear that discovery would lead to his losing his social position), found a way to transform himself and thereby indulge his vices without fear of detection. But as Jekyll used Hyde to act out his desires more and more, he effectively became a sociopath — evil, self-indulgent, and utterly uncaring to anyone but himself. Initially, Jekyll was able to control the transformations, but then he became Hyde involuntarily in his sleep.
At this point, Jekyll resolved to cease becoming Hyde. One night however, the urge gripped him too strongly. After the transformation, he immediately rushed out and violently killed Carew. Horrified, Jekyll tried more adamantly to stop the transformations, as now his scapegoat was no longer safe. For a time, he proved successful by engaging in philanthropic work. One day at a park, he considered how good a person he had become as a result of his deeds (in comparison to others), believing himself redeemed. However, before he completed his line of thought, he looked down at his hands and realized that he had suddenly transformed once again into Hyde. This was the first time that an involuntary metamorphosis had happened in waking hours. Far from his laboratory and hunted by the police as a murderer, Hyde needed help to avoid being caught. He wrote to Lanyon (in Jekyll's hand) asking his friend to retrieve the contents of a cabinet in his laboratory and to meet him at midnight at Lanyon's home in Cavendish Square. In Lanyon's presence, Hyde mixed the potion and transformed back to Jekyll - ultimately leading to Lanyon's death. Meanwhile, Jekyll returned to his home only to find himself ever more helpless and trapped as the transformations increased in frequency and necessitated even larger doses of potion in order to reverse them.
Eventually, the stock of ingredients from which Jekyll had been preparing the potion ran low, and subsequent batches prepared by Dr. Jekyll from renewed stocks failed to produce the transformation. Jekyll speculated that the one essential ingredient that made the original potion work (a chemical salt) must have itself been contaminated. After sending Poole to one chemist after another to purchase the salt that was running low only to find it would not work, he assumed that subsequent supplies all lacked the essential ingredient that made the potion successful for his experiments. His ability to change back from Hyde into Jekyll had slowly vanished in consequence. Jekyll wrote that even as he composed his letter, he knew that he would soon become Hyde permanently, having used the last of this salt and he wondered if Hyde would face execution for his crimes or choose to kill himself. Jekyll noted that in either case, the end of his letter marked the end of his life. He ended the letter saying "I bring the life of that unhappy Henry Jekyll to an end". With these words, both the document and the novella come to a close.
The original pronunciation of "Jekyll", as used in Stevenson's native Scotland, rhymed with "treacle", thus (//).

In the course of the series, it is revealed that the original Jekyll's transformation into Hyde was a 'natural' process, triggered by Jekyll's love for his maid rather than any kind of potion, and Jackman is the descendant of one of Hyde's bastard sons, while his wife is a clone of Jekyll's maid created by a corporation to try and duplicate the Hyde process. As with most modern adaptations, Hyde is depicted as possessing superhuman strength, able to tear a lion apart with his bare hands, and is depicted as being impulsive and childish rather than explicitly evil, although the physical changes are fairly subtle, such as Hyde having darker eyes and a different hairstyle. At the series' conclusion, Hyde apparently sacrifices himself to save Jackman, "dying" when he is shot but somehow able to stop Jackman "sharing the damage", with the result that the bullets remain in Jackman but he has no injuries to demonstrate where they entered his body.
- NBC's Do No Harm is a modern retelling of the Jekyll and Hyde story featuring a renamed Jekyll-like character named Dr. Jason Cole (played by Steven Pasquale) trying to stop his drug-addicted, sociopathic, Hyde-like counterpart named Ian Price from ruining his professional and private life.

- Dr. Jekyll and Mr. Hyde appear in Mad Monster Party?, voiced by Allen Swift. Dr. Jekyll and Mr. Hyde appear as guests at a party thrown by Baron Boris von Frankenstein at his castle on the Isle of Evil.

- The film The League of Extraordinary Gentlemen (adapted from the comic book series) features Jason Flemyng as both Dr. Jekyll and Mr. Hyde (the latter using prosthetic makeup to appear as a Hulk-esque version of the character with superhuman strength). Dr. Jekyll and Mr. Hyde are employed by The League of Extraordinary Gentlemen to combat the ruthless criminal known as the Fantom, who is revealed in the course of the film to be "M", the man who recruited them, and also Professor Moriarty, who intends to acquire the power of the League for use in his plans to trigger a world war and sell his weapons for profit. His mole in the League, Dorian Gray, manages to acquire a sample of the Hyde serum, which he is able to duplicate, one of Moriarty's men drinking a massive overdose of the Hyde serum to become an even larger version of Hyde. Despite the other Hyde's size and raw power, he is defeated when he burns through the formula at an accelerated rate, resulting in Moriarty's fortress collapsing on top of him.
- Dr. Jekyll and Mr. Hyde appear in Van Helsing, with Dr. Jekyll portrayed by Stephen Fisher while Robbie Coltrane provides the voice of the CGI animated Mr. Hyde. Like the version that was seen in The League of Extraordinary Gentlemen, Mr. Hyde is also portrayed as a large, hulking brute. Van Helsing has pursued Hyde to Paris after having failed to capture him in an earlier confrontation in London, England. He is superhumanly strong and displays agility comparable to that of a great ape. While not invulnerable, he's extremely tough and sustains severe injuries that ultimately do little to impede or slow him down to any appreciable degree. Upon exchanging banter, they begin fighting in the bell tower of Notre Dame Cathedral with Van Helsing initially gaining the advantage by severing Hyde's left arm at the biceps, which regresses to a normal form after landing on the floor. Hyde rallies and assaults Van Helsing, using his right arm to hurl him through the roof of the cathedral. He then gloats before tossing Van Helsing off the roof only for Van Helsing to fire a grappling gun that sends the hook & line through the center of Hyde's body, which Van Helsing uses to stop his fall. He attempts to pull Hyde off the roof, only for Hyde to begin pulling him upward, seemingly unfazed by the large hole in his body. Hyde trips over the edge of the roof, his falling weight pulling Van Helsing up to the roof before the line breaks. As it breaks, the momentum swings Hyde through the Rose Window of the cathedral and, while he falls, Hyde transforms back into the form of Henry Jekyll and dies from the fall. A police officer spots Van Helsing on top of the cathedral and holds him accountable for Dr. Jekyll's death.
- The novelization of the film portrays Hyde as not only a murderer, but a cannibal as well. The novel says the body of the murdered woman Van Helsing discovers on the streets of Paris as partially devoured while the same scene in the film shows the woman's body intact. However, the film does suggest that Hyde is cannibalistic when he encounters Van Helsing in Notre Dame and tells him "You're a big one. You'll be hard to digest." In the Game Version Hyde tells Van Helsing that he is responsible for the murders and digestion of several people including children.
- The Ghost of Mr. Hyde made a cameo in Scooby-Doo! and the Goblin King as a patron in a monster bar.
- The Dynomutt version of Mr. Hyde appeared in Scooby-Doo! Mask of the Blue Falcon, voiced by John DiMaggio.
- Russell Crowe played Dr. Jekyll in The Mummy, which is the first and only installment in Universal's Dark Universe and is a role which would have been elaborated on in further films within the series. It is suggested that Jekyll's transformation into Hyde was a "natural" condition, as he reflects on how someone- implied to be him- realized that he was succumbing to evil but was able to find a cure as a physician, requiring regular injections of an unspecified compound to prevent himself becoming Hyde, an aggressive and sadistic persona. Despite the personality transformation, Dr. Jekyll and Mr. Hyde have the same appearance with the exception of their skin and eyes, although they also have a different palmprint with the result that palm scanners that will allow Jekyll access will prohibit Hyde from using the same door. As Hyde, he exhibits greater levels of physical strength, endurance and aggression as well as improved combat abilities.
- Henry Jekyll, better known as Edward "Eddy" Hyde, was mentioned many times in the 2022 live action film on Monster High. After he was expelled from Monster High because of his human half, Eddie Hyde worked on a formula to make him more monstrous. Unfortunately, he never got around to using it due to the fact that he was killed by the monster hunters. Eddy Hyde was revealed to have a son named Edward "Eddy" Hyde Jr. who went under the alias Mr. Komos and sought out his father's work.
- In The League of Extraordinary Gentlemen, Volume One and Volume Two by Alan Moore and Kevin O'Neill, Henry Jekyll is a scientist who is the lesser half of Edward Hyde and member of the Victorian League. This incarnation of Jekyll and Hyde reveals that eventually Jekyll found that he would transform into Hyde under stress, not unlike Hulk. Likewise, Hyde has become progressively taller and bulkier than Jekyll, while Jekyll has become shorter and withered. During a dinner scene, Hyde explains that this is because splitting himself and Jekyll into separate identities resulted in him losing his restraints and growing beyond his original limits, while Jekyll withered away without anything to drive him. During the Martian invasion, he developed a strong respect for Mina Murray and sacrificed himself to stop Martian tripods from crossing London Bridge. His self-sacrifice was honored in having Serpentine Park named into Hyde Park and a statue of Mr. Hyde is seen in the park in The League of Extraordinary Gentlemen: Black Dossier and throughout The League of Extraordinary Gentlemen, Volume III: Century.
