“That crazy arsehole's running free and he scares everybody - gangstas, raskols, terrorists, hitmen for the Russian fucking mafia!”
— Angel, referring to the Banoi Butcher
He gives the Hero the side quest "Banoi Butcher," in which the Hero must find and kill the Banoi Butcher. He gives the Hero a Zed's Demise once they finish the quest. He states that having the Banoi Butcher dead would ease some tension for the prisoners.
Angel is later killed during the overrun, along with most of the others.
