In the Hindu epic Mahabharata, the Upapandavas (, उपपाण्डव, lit. junior Pandavas), also known as Pandavaputras (, पाण्डवपुत्र, lit. sons of Pandavas), Draupadeyas or Panchakumaras (, पञ्चकुमार, lit. five sons) are the five sons of Queen Draupadi from each of the five Pandavas. They are Prativindhya, Sutasoma, Shrutakarma, Shatanika and Shrutasena. They were Atirathis, as mentioned by Bhishma, and fought the Kurukshetra war on the side of the Pandavas and slew many enemy warriors. They were as ferocious as their fathers but other than that, not much is said in the Mahabharata about the brothers. They were very strong and they were only defeated by remarkably few Kaurava warriors.
They had half and full paternal brothers, 3 of whom - Abhimanyu, Ghatotkacha and Iravan, also fought in the War. All 8 of these brothers perished in the battle.
The Upapandavas, along with Abhimanyu, also battled the demon king Alambusha, on the 9th day but they were all defeated by Alambusha and Abhimanyu had to come to their rescue. On the 11th day, Nakula's son Shatanika was defeated by Vrihasena, the son of Karna.
Prativindhya (, प्रतविन्ध्य, lit. shining like the sun or towards Vindhya) or Shrutavindhya (, श्रुतविन्ध्य, lit. related to the Buddhi) was son of Yudhishthira and Draupadi and was the eldest of the Upapandavas. He was described to be a skilled fighter, known to face troops like "the thunder-wielding Shakra (Indra)".
In the Kurukshetra War, Prativindhya fought Shakuni. On the 9th day, Prativindhya struck Alambusha unconscious.
On the 14th night, he fought some of the Kauravas along with Sutasoma. On the 15th day, he stopped Ashwatthama's advance by holding him off long enough but ultimately had to retreat from the battle after being overpowered by Drauni. He killed Chitra, the king of Abhisara, on the 16th day.
(सुतसोम, lit one who has extracted soma or the one who has the beauty of the moon) was son of Bhima and Draupadi, second of the Upapandavas. He excelled in Mace fighting and archery. He battled the Kaurava prince Vikarna on the first day of the war.
