Personality
Sir Hugh Irons has a rather calm yet stern personality which is seen in OVA II, when on learning of the Valentine Brothers' attack, Sir Shelby Penwood freaked out but Sir Hugh Irons remained calm and told Sir Penwood to calm down and when he tells Integra Hellsing that the aftermath of the Valentine brothers' invasion is her responsibility and when Integra orders Walter to put the ghouls of the Hellsing Estate Guards out of their misery, he orders Integra that as their commander, its her responsibility.

Trivia
