Isumatar is sadistic, ruthless, and short-tempered. Anyone working for him is simply a tool and anyone neutral or against him is someone that must be disposed of immediately.
Isumatar's father Ginkaku was born in the Northern Water Tribe and operated a small-time gang there. However, his attempt to expand his sphere of influence was not received kindly by the Water Tribe leadership and he and his family were exiled when Isumatar was two years old. Ginkaku settled in a Fire Nation village and before long resumed his gangster ways, gathering a sizeable following.
When Isumatar turned five years old, it was discovered that he was a waterbender, the first in his family in generations. From that moment on, Ginkaku foresaw greatness in his son and groomed him as his heir apparent. Isumatar's sister Mei was three years his junior and was gifted with no such abilities. Ginkaku ignored Mei entirely and Isumatar soon learned to follow this example and began to see her not as his sister but as a nuisance.
When Isumatar was 18, his father was killed in a turf war and Isumatar took his place as leader of the gang. Isumatar proved to be an even more ruthless leader than his father and before long set his eyes on his sister as a hindrance that must be dealt with. He sent her off in a mission alone, where she was told she'd be a hero when she returned- all she had to do was spy on a rival gang. However, Isumatar had tipped off the rival gang and paid them to kill her.
Assuming that she was dead, Isumatar and his gang carried on business as usual. However, over the next year a drought hit the town and left it in utter poverty. With their fortunes dried up, the members of Isumatar's gang all turned on each other and fought bitterly until only Isumatar was left. With no reason to stay in the Fire Nation, Isumatar set off for Republic City to make a name for himself there. A year after arriving in the city, he learned from a surviving member of the rival gang that his sister had survived and was somehow in the city. Deluding himself that she was to blame for the misfortune that had befallen he and his gang, Isumatar has resolved that he will not rest until he has hunted her down and made her pay.
