Fabian Fuchs is one of the infamous Fuchs terrorist brothers, one of 47's genetic uncles (since he is Franz Fuchs's brother), and the first one to be killed by 47. He is a target in The Bjarkhov Bomb.
He was sent to make a deal with former Red Army officer Sergei Bjarkhov at his Siberian bomb production facility in order to purchase some of his bombs, but 47 was sent to kill them both.
