Sukumara
“And the son of Kunti (Bhimasena), having vanquished that monarch by performing feats that excelled in fierceness, subjugated the eastern region. Then that prince of the Kuru race, endued with great prowess going into the country of Pulinda in the south, brought Sukumara and the king Sumitra under his sway.”
