Yuyudhana (Sanskrit: युयुधान, Yuyudhāna), better known as Satyaki (Sanskrit: सात्यकी, Sātyakī), was a powerful warrior belonging to the Vrishni clan of the Yadavas, to which Krishna also belonged. According to the Puranas, he was grandson of Shini of the Vrishni clan, and son of Satyaka. Satyaki was devoted to Krishna and was student of Arjuna as well as co-student under Dronacharya. Satyaki was a valiant warrior and on one particular occasion, Drona was stunned when Satyaki broke his bow for 101 times successively. He is also known as the unconquerable Satyaki.
