Professor Richard Lazarus was a man who craved immortality.
Biography
Childhood
Lazarus was only a child during World War II but had vivid memories of it. He hid in Southwark Cathedral during the London Blitz with others. He sat in the crypt, the living amongst the dead and feared death. His childhood home was destroyed in the bombing.
Genetic manipulation
Lazarus built a Genetic Manipulation Device with financial backing from Harold Saxon. It took him many years to complete, and he was seventy-six years old when he finished it. When interviewed on television, he spoke of how his experiment would "change what it means to be human."
The head of PR, Tish Jones, organised an unveiling of the experiment. He stepped into the machine when it was activated. Despite engineering faults, the machine worked, taking thirty years off his age. He stepped out a younger man.
After effects
Unbeknownst to Richard, the process had activated dormant genes in his DNA. They refused to settle down and he transformed into an alternate evolution of humanity which fed on human life energy. In this form he killed his associate, Sylvia Thaw, draining her of life. Lazarus then returned to human form. He needed still more for the mutation to stabilise, so he took Tish up to the roof, intending to drain her. The Tenth Doctor and Martha Jones interrupted them and ran from him as he again mutated. He chased them down to the main room where he drained another victim.
The Doctor distracted him, leading him to a lab where he caused an explosion. This only angered Lazarus, who continued his pursuit. Martha and the Doctor hid within the Genetic Manipulation Device, knowing Lazarus would not want to damage it. Lazarus activated it but the Doctor altered it so that it let out a blast that incapacitated Lazarus. He changed back to human form and, seemingly dead, was taken away in an ambulance.
Death and legacy
Lazarus had, however, survived the blast. He recovered and drained the two ambulance men with him. He then escaped the ambulance and hid in Southwark Cathedral. He chased Tish and Martha up to the bell tower, mutating again. While he was there, the Doctor used the amplified noise of the organ to confuse and injure Lazarus, mere seconds before Lazarus could drain Martha. He lost his balance, fell from the tower to his death and his corpse changed into his young human form, then into his old form. (TV: The Lazarus Experiment)
The Tenth Doctor later saw him among many distorted illusions created by the Door. (COMIC: Destiny's Door)
Undated events
At some point during the events of his mutation, he visited Penhaxico Two. (COMIC: Escape to Penhaxico)
Personality
Lazarus' main desire was to obtain immortality. This was motivated by his traumatic experiences as a child during World War II. He was willing to go to any lengths to obtain his ultimate goal, having worked his whole life on his machine. Once he mutated, this trait of his character only worsened, as he was more than willing to succumb to his hunger and feed off innocent people just to prolong his own life. When the Tenth Doctor told Lazarus about the burdens of a long lifespan such as a Time Lord's and the horror of seeing everyone he cared about die around him, Lazarus simply brushed it off and called it "a price worth paying".
Another prominent aspect of his personality was his womanising tendencies. Even when he was 76 years old, he flirted with Tish Jones. It should be noted that all members of his staff appeared to be young women in their twenties. Once he was rejuvenated, he became more openly flirtatious and was seen having his picture taken with numerous young women around him.
Lazarus was also incredibly vain. He payed no attention to the Tenth Doctor's warnings about the uncertainty of the machine's process and once he had transformed, he called his mutation "progress". In a successful attempt to provoke him and spare Martha's family, the Doctor called Lazarus "a vain old man who thought he could outsmart nature" and "a joke".
Powers and abilities
After having stepped out of his machine, Lazarus soon mutated into a gigantic hideous creature that was actually an evolutionary throwback. Though this option was rejected by evolution for humanity millions of years ago, the Tenth Doctor stated that the potential was still there, locked away in humans' genes, suggesting that human who underwent the same process would suffer the same mutation.
In his mutated form, Lazarus displayed superhuman strength thanks to his massive size. He hurled a table at Leo Jones with such force that it knocked him out. Due to his extra limbs, he was also gifted with superhuman agility and dexterity. Despite being massive in size, he could easily fit through doors and even climb along walls and ceilings.
He also demonstrated incredible durability and resistance to damage, surviving an enormous explosion set off by the Tenth Doctor without a scratch. A powerful blast of hypersonic soundwaves left him seemingly dead only for Lazarus to recover minutes later. He was finally killed when he fell from the top of the bell tower of Southwark Cathedral, dying upon impact.
His most fearsome weapon was a massive tail similar to that of a scorpion. By stabbing a victim with the two pincers on the end, Lazarus could drain a human of all their life energy in seconds. This inevitably killed the victims, which were reduced to dessicated husks.
Behind the scenes
- Mark Gatiss, a longtime Doctor Who fan with several writing credits connected with the series, played Lazarus in both his young and old human forms.
- Neill Gorton claimed that the prosthetic face for the older Lazarus was partially modelled on Vincent Price. (CON: Monsters Inc.)
- The character's surname was a reference to the biblical character of Lazarus, whom Jesus raised from the dead. The Doctor made reference to this when he discovered that Lazarus had "risen from the dead" and escaped from the ambulance.
