Elliot Alderson is the main protagonist of the 2015 series Mr. Robot. He is a cyber-security engineer by day and a vigilante hacker by night. He suffers from a plethora of mental illnesses such as depression, social anxiety, PTSD and DID. He usually narrates his life to the audience whom he refers to as a friend. His unreliable narrator status sometimes make us question whether or not anything he says is real
He is portrayed by Rami Malek.
Elliot is shown to be an introvert but a broken person, who has so much anger towards society. He always wears his signature black hoodie to blend into the world. He suffers from too many mental illnesses throughout the series such as depression, anxiety, delusions, paranoia, PTSD and Dissociative Identity Disorder. As a result, he finds it difficult to have relationships with other people. But despite all of this, he appears to be more kind, caring and compassionate towards others. He uses his hacking skills for good by taking down criminals and abusers and connect with other people.
Despite fighting his own demons, he still cares for others and tries to help them like when he defended Angela after the E Corp CTO insulted her and when he comforted Trenton's brother Mohammed when he was grieving over her death.
From what we know about his childhood, Elliot had a good relationship with his father and was the only person he could talk to. He lost his father to leukemia, which was caused by a toxic leak in the E Corp Washington Township plant. Edward tried to keep his cancer a secret from his family, but when Elliot told others, he threw him out of the window angrily (later revealed that Elliot jumped out of the window and was not pushed).
Elliot did not have a good relationship with his mother, as she was very abusive towards him and his younger sister Darlene, physically, mentally and emotionally.
