He has a friendly and refreshing personality, though he has an unusual accent and speech patterns. Despite his mature appearance, he is surprisingly easy to hurt, getting depressed whenever people harp on him about his age. He speaks in the third person with a Russian accent in the English version. Gregor's age blesses him with fighting skills that impress even Lon'qu. Despite his looks and behaviour, Gregor is quite wise, knowing how old Nowi actually is and seeing beyond her youthful facade, having knowledge of health and diseases, and giving advice to other members in the army.
