The son of the tribal chief Hiranyadhanus. He approached Drona to teach him weaponry, but was rejected because he was a tribal. Not to be disheartened, Ekalavya left after prostrating himself at Drona’s feet. Back in his forest, he made a clay statue of Drona and started practicing archery. Once the Pandavas and Kauravas went into the forest for a hunt. Their dogs saw Ekalavya and started barking. One of the dogs advanced on Ekalavya, who fired seven arrows into its mouth. It ran back to the Pandavas who then met Ekalavya. Ekalavya claimed he was Drona’s disciple. A disappointed Arjuna went back and told Drona that though he had promised that Arjuna would be unrivaled in archery, another of Drona’s disciple was better. Drona went into the forest to meet Ekalavya, who bowed on seeing his guru. Drona told Ekalavya that if he considered him his guru, he would need to give a gurudakshina. Drona asked him to cut off his right thumb, and Ekalavya promptly did so. Arjuna remained unrivaled, as per Mahabharata Adiparva Chapter 132.

As per Mahabharata Udyogaparva Chapter 48 verse 77, Ekalavya was killed by Krishna.

According to Mahabharata Ashwamedhikaparva Chapter 83, one of Ekalavya’s sons followed Arjuna’s ashwamedha horse and was defeated by Arjuna.
