O-5, like most notails, is highly impersonal and always on the move, heading to his next task of the day the moment the other is finished. Most would assume that O-5, being of the highest class of notail, would be quick to tell everyone about it so that he may use his status as a tool to get what he wants, but this is not what O-5 does. O-5 never brings up his status, and while he is required to wear his letter and number on his shirt he hopes that many of the people he meet either do not notice it or do not know what it means.

O-5 is amused by how people judge him based on his looks and actions rather than his class. He finds this judgment most interesting and always keeps notes on what these people think of him. The people O-5 hates the most are people who call him an abomination for his prosthetic legs. When O-5 meets people like this, he is quick to kill people like those with a swift kick.
