An SAS veteran, Fergus joined as a boy soldier before being badged into the SAS. He is 5 foot and 11 inches, has grey hair, blue eyes lean and wiry and limps due to bullet wound in right thigh. He was highly decorated and participated in many wars. At 18 years old, he married and had a son. However, he left his family to be with his comrades. Fergus was found by his grandson Danny and by a team of MI6 operatives. He led Danny to safety and started to train him as a boy soldier. Though they were estranged at the beginning, they started to grow closer and Fergus acted as a father figure for both Danny and Elena. After Fincham's death at the hands of Marcie Deveraux, Fergus, Danny and Elena were hired by MI5 to bring down 'Black Star', the mysterious leader of a teenage-suicide bombing network. Fergus's primary concern however remained Danny and Elena's safety and he blackmailed Deveraux by holding all of her information about the op that he threatened to give to the FBI. However, he was unable to save Elena and had to face Danny's anger about it. He was chosen by MI5 to lead the team chosen for the Meltdown operation and had to try to quench Danny's desire for revenge against Deveraux. Fergus is depicted as a surprisingly composed and observant soldier, despite his experiences and severe suffering, though often disregarding Danny's contribution and disgruntled with weighting the responsibility of his grandson, he ultimately comes to accept Danny as his grandson and deeply admire his bravery and love him, this shown during Payback when he is seen to be crying over Danny.
