Personality
In general, Ko Sharmus appeared to be a kind and gentle man with an extremely friendly personality.
Ko Sharmus was a warrior who fought for humanity during the Cyber-Wars, something he retained even in old age. He showed himself to be extremely selfless, effectively sacrificing his own life by remaining behind as a ferryman for those who sought to use the Boundary to escape, even when it had been so long that he believed humanity had gone extinct aside from those who had already escaped. However, Ko Sharmus didn't appear to find this as noble as it sounded from his response to the Thirteenth Doctor when she pointed out how selfless he was. Though he hoped he'd fought his last battle a long time before by the time the Doctor found him, Ko Sharmus still retained his warrior spirt and claimed to still know a few tricks and expressed confidence in his knowledge of the Cybermen.
As part of the Alliance that sent the Cyberium back through time and space, Ko Sharmus felt a great deal of guilt and remorse as he believed himself to be responsible for Ashad's actions and by extension, the army of CyberMasters created by the Spy Master. Ko Sharmus felt that by saving the Doctor he could in some way make up for his mistake. In his final moments, Ko Sharmus showed nothing but defiance in the face of the Master, taunting him with his last words. (TV: Ascension of the Cybermen, The Timeless Children)
