Aiden Pearce is the primary protagonist of the open world video game Watch Dogs, a minor character in Watch Dogs 2, and an upcoming character in Watch Dogs: Legion. He is a highly skilled and very deadly computer hacker and ex-Fixer who has access to the CtOS of Chicago through the use of a device called a Profiler, and is obsessed with surveillance, protection and control. People that he loved were afflicted in the past and are being attacked once more, so he has become a vigilante in an attempt to prevent this. His obsession has reached the point where he even monitors his own family, primarily his own sister, although they are not aware of this. He has been described as in a "gray area".
