In the Ramayana, Indrajit (also known as Meghanada), Ravana's son, used the Nagapasha weapon to capture Rama and Lakshmana during the battle in Lanka. This serpent weapon made them unconscious. Ravana was the demon king, Atikaya was another powerful warrior son of Ravana, and Kumbhakarna was Ravana's brother known for his deep sleep.
