Liam is an unhinged, aggressive ex solder who was discharged from the military (UKSF) due to poor mental health. He dislikes authority figures and seeks control. He creates unhinged trials for people he abducts and attempts to kill those he considers unworthy, and recruit  those who he thinks would be worthy to join him in his crusade.
Manipulative and secretive, Liam presents himself as non threatening until he can win the trust of people. He is a charismatic liar.
