Mbh 1.230.2a

“Vaisampayana said, ‘Then the inhabitants of the forest of Khandava, the Danavas and Rakshasas and Nagas and wolves and bears and other wild animals, and elephants with rent temples, and tigers, and lions with manes and deer and buffaloes by hundreds, and birds, and various other creatures, frightened at the falling stones and extremely anxious, began to fly in all directions. They saw the forest (burning all around) and Krishna and Arjuna also ready with their weapons. Frightened at the terrible sounds that were audible there those creatures lost their power of movement. Beholding the forest burning in innumerable places and Krishna also ready to smite them down with his weapons, they all set up a frightful roar. With that terrible clamour as also with the roar of fire, the whole welkin resounded, as it were, with the voice of portentous clouds. Kesava of dark hue and mighty arms, in order to compass their destruction, hurled at them his large and fierce discus resplendent with its own energy. The forest-dwellers including the Danavas and the Rakshasas, afflicted by that weapon, were cut in hundreds of pieces and fell unto the mouth of Agni. Mangled by Krishna’s discus, the Asuras were besmeared with blood and fat and looked like evening clouds. And, O Bharata, he of the Vrishni race moved able like death itself, slaying Pisachas and birds and Nagas and other creatures by thousands. The discus itself, repeatedly hurled from the hands of Krishna, that slayer of all foes, came back to his hands after slaughtering numberless creatures. The face and form of Krishna that soul of every created thing--became fierce to behold while he was thus employed in the slaughter of the Pisachas, Nagas and Rakshasas. No one among the celestials, who had mustered there could vanquish in battle Krishna and Arjuna. When the celestials saw that they could not protect that forest from the might of Krishna and Arjuna by extinguishing that conflagration, they retired from the scene.
