Mbh 5.22.1d

That one in their midst, who, having been endued with blazing beauty, shone like the sun, whom all persons deemed unassailable in battle and the very best of all drawers of the bow on earth, was slain by Krishna in a trice, by help of his own great might, and counting for naught the bold spirit of all the Kshatriya kings. Kesava cast his eyes on that Sishupala and smote him, enhancing the fame and honour of the sons of Pandu. It was the same Sishupala who was highly honoured by those kings at whose head stood the king of the Karusha tribe. Then the other kings, deeming Krishna unassailable when seated on his car drawn by Sugriva and other steeds, left the chief of the Chedis and ran away like small animals at the sight of a lion. And it was thus that he, who, from audacity had sought to oppose and encounter Krishna in a combat hand to hand, was slain by Krishna and lay down lifeless, resembling a Karnikara tree uprooted by a gale. O Sanjaya, O son of Gavalgana, what they have told me of the activity of Krishna in cause of Pandu’s sons, and what I remember of his past achievements, leave me no peace of mind. No foe whatsoever is capable of withstanding them, who are under the lead of that lion of the Vrishni tribe. My heart is trembling with fear upon learning that the two Krishnas are seated on the selfsame car. If my dull-headed son forbear to fight with those two, then may he fare well,--else those two will consume the race of Kuru as Indra and Upendra consume the Daitya hosts. Dhananjaya is, I conceive, equal to Indra, and the greatest of the Vrishni race, Krishna, is the Eternal Vishnu himself. The son of Kunti and Pandu, Yudhishthira, is virtuous and brave and eschews deeds that bring on shame. Endued with great energy, he hath been wronged by Duryodhana. If he were not high-minded, he would in wrath burn the Dhritarashtras.
