| — Malcolm to Lucifer|
Malcolm Graham was a major villain in the first season of Lucifer. He was a corrupt homicide detective in Los Angeles, working as a member of the LAPD. After his true nature was exposed to the department, he tried to escape to city but was eventually shot and killed by fellow detective Chloe Decker.
Malcolm was shot by Dan Espinoza while meeting up with some gang members and fell into a coma for months. Chloe Decker believed he was on the take, but the other cops didn't think so and didn't look into it.
Before his brief lapse of death, it is implied that he was a corrupt and amoral cop, working with gangsters and LA's underground as an informant.
Since his resurrection by Amenadiel, Malcolm is shown to be devious and unchecked, even admitting himself that his time in Hell left him deranged. He is psychopathic, killing whenever he sees an opportunity to use it, such as when he killed his own partner and framed it as a suicide as a favor to Dan. He is seen stuffing his face with platters of food and acting out various, hedonistic impulses, implied to have been due to the starvation he faced during his period in Hell.
Despite whatever apathy he has for authority, he does honor whatever agreements he has with those he bargains with. He hatches a scheme to kill Lucifer and frame Dan for his murder when told to kill him by Amenadiel, only to decline when Lucifer tells him that angels do not have any control over a soul's fate, nor are they allowed to kill mortals. He then proceeds to kill satanists Rose Davis and Corazon with the intentions of framing Jacob Williams for them out of a twisted sense of loyalty to Lucifer, thinking that Lucifer would appreciate killing "frauds".
- Skilled Hand-to-hand Combatant - As a policeman, Malcolm is skilled in close combat. He managed to overpower and knock out the larger Dan while handcuffed.

- He was in Hell for a short period of time before being brought back to life. However, it felt like an eternity for him. His punishment consisted of being starved, due to his hunger for life. This included denying him access to food, water, people, and entertainment.
