Sutasoma
Sutasoma (Sanskrit: सुतसोम, lit one who has extracted soma or manifestation of the mind) was son of Bhimasena and Draupadi, the second of the Upapandavas. The Upapandavas were the five sons born to Draupadi from each of the five Pandavas. They are: Prativindhya from Yudhishthira, Sutasoma from Bhimasena, Shrutakarma from Arjuna, Shatanika from Nakula and Shrutasena from Sahadeva. They fought the battle on the side of the Pandavas, and all were Ekarathis as said by Bhishma but not much is said in the Mahabharata about the brothers except for fleeting mentions during the battle. On the 11th and 14th day of war, all five were single handedly defeated by Karna's son Vrishasena. All the Upapandavas were killed by Ashwatthama on the night of the last day of the war.
On the 12th day of war
Vivimshati resisted the heroic Sutasoma of great prowess, as the latter advanced towards Drona, scattering showers of arrows. Sutasoma, however, excited with wrath, pierced his uncle Vivimshati with straight arrows, and cased in mail, stood ready for the combat.
