Sumaan schemed with his brother's enemy, Queen Bee, to attain popularity and facilitate her slow takeover of the neighboring country. They hired the assassin Deadshot to "assassinate" Rumaan at a public speaking event, giving Sumaan enough time to dive in the line of fire and catch the bullet with his body. For saving his brother's life, he was elevated to national hero.
After the assassination of his brother, Sumaan came to power in Qurac. Much to the grievance of his niece Noor, she realized Sumaan was a puppet of Queen Bee, even though he pretended not to be. Following the invasion and annexation of Qurac, Sumaan was made the UN ambassador to Greater Bialya.
During a meta-human summit in the General Assembly, Harjavti attacked Atlantis's ambassador Garth and Themysciran ambassador Troia for their support of the Justice League. He wanted to know why no Bialyan heroes had been invited to join. Troia shut him by pointing out all Bialyan meta-humans were wanted criminals.
