Lazarus was also incredibly vain, to the point of developing a God complex: after he had become younger, he developed the concept that he was immediately superior to everyone else. However, in his mutated form, Lazarus outright discarded any adoration for women (or, indeed, human beings), citing their slaughter to be a necessary sacrifice, even though their deaths achieved nothing but showing him to be so much of a monster. He would resort to womanising on two occasions before his death, the first with Lady Thaw (where he utilised it in an argument they were having though he stopped kissing her because of her age) and Tish Jones (only minutes later, showing he had essentially discarded Lady Thaw after killing her). Once he was rejuvenated, he became more openly flirtatious and was seen having his picture taken with numerous young women around him. It should be noted that all members of his staff appeared to be young women in their twenties. Even when he was 76 years old, he flirted with Tish Jones, who originally viewed him as a repulsive man when he made such advances and made her disgust obvious. 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".Īnother prominent aspect of his personality was his womanising tendencies. 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. He was willing to go to any lengths to obtain his ultimate goal, having worked his whole life on his machine. This was motivated by his traumatic experiences as a child during World War II, which left him with an intense case of thanatophobia. Lazarus' main desire was to obtain immortality. 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. 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 chased Tish and Martha up to the bell tower, mutating again. He then escaped the ambulance and hid in Southwark Cathedral. He recovered and drained the two ambulance men with him. Lazarus had, however, survived the blast. He changed back to human form and, seemingly dead, was taken away in an ambulance. Lazarus activated it but the Doctor altered it so that it let out a blast that incapacitated Lazarus. Martha and the Doctor hid within the Genetic Manipulation Device, knowing Lazarus would not want to damage it. This only angered Lazarus, who continued his pursuit. The Doctor distracted him, leading him to a lab where he caused an explosion. Lazarus mutates into a hideous creature, thanks to an evolutionary throwback. He chased them down to the main room where he drained another victim. The Tenth Doctor and Martha Jones interrupted them and ran from him as he again mutated. He needed still more for the mutation to stabilise, so he took Tish up to the roof, intending to drain her. In this form he killed his associate, Sylvia Thaw, draining her of life. They refused to settle down and he transformed into an alternate evolution of humanity which fed on human life energy. Unbeknownst to Richard, the process had activated dormant genes in his DNA. Despite engineering faults, the machine worked, taking thirty years off his age. He stepped into the machine when it was activated. The head of PR, Tish Jones, organised an unveiling of the experiment. The rejuvenated Lazarus.( TV: The Lazarus Experiment) When interviewed on television, he spoke of how his experiment would "change what it means to be human." It took him many years to complete, and he was seventy-six years old when he finished it. Lazarus built a Genetic Manipulation Device with financial backing from Harold Saxon. His childhood home was destroyed in the bombing. He sat in the crypt, the living amongst the dead and feared death. He hid in Southwark Cathedral during the London Blitz with others. Lazarus was only a child during World War II but had vivid memories of it.
