Hero of Pandava and The Son of Kunti by the blessing of Indra the God of Storm, he was the third of the Pandava brothers. Arjuna was a master archer and strategist, in his youth he was a brilliant student favored by Drona.
Arjuna was a key warrior from the Pandava side and slew many warriors. Khrisna was his mentor and charioteer in The Great War, who gave him the knowledge of Bhagavad Gita to overcome his moral dilemma.
Although they are both brothers born from the same womb, Karna and Arjuna were an archnemesis, at the end of Bharatayuddha none will live if the other one still stands.
