Genma is shown to be very calm, impartial, collected, proud and casual on his actions. He is never seen being boisterous or lost in difficult situations and is confident enough to take charge of large groups of ninja. It was also stated that he hates Orochimaru for power-playing. He is also a jovial person, prone to wisecracking at times. When Shikaku Nara contacted him, he made it a point to first tell Genma not to make fun of the situation.
