Nakula
“All of them, on the occasion of the campaign of universal conquest, vanquished great kings, O bull of Bharata’s race! No other men can wield their weapons, maces, and shafts. Indeed, O Kaurava, there are no men that can even string their bows, or uplift their maces, or shoot their arrows in battle. In speed, in hitting the aim, in eating, and in sports on the dust, they used to beat all of you even when they were children. Possessed of fierce might they will, when they encounter this force, exterminate it in battle. A collision, therefore, with them is not desirable. Each of them can alone slay all the kings of the earth! That which happened, O great king, on the occasion of the Rajasuya sacrifice, had occurred before thy very eyes!” -The Mahabharata, Book 5: Udyoga Parva: Uluka Dutagamana Parva: Section CLXX
“Then Sushena, filled with rage, struck the son of Pandu with three shafts and Sutasoma with twenty in the arms and the chest. At this, the impetuous Nakula, O monarch, that slayer of hostile heroes, covered all the points of the compass with arrows. Then taking up a sharp shaft endued with great energy and equipped with a semi-circular head, Nakula sped it with great force at Karna’s son in that battle. With that arrow, O best of kings, the son of Pandu cut off from Sushena’s trunk the latter’s head in the very sight of all the troops. That feat seemed exceedingly wonderful. Thus slain by the illustrious Nakula, Karna’s son fell down like a lofty tree on the bank of a river thrown down by the current of the stream. Beholding the slaughter of Karna’s sons and the prowess of Nakula, thy army, O bull of Bharata’s race, fled away in fear.” – The Mahabharata, Book 9: Shalya Parva: Section 10
