Indrajeet, (which means the conqueror of Indra, the king of gods) is the son of Ravana, the ten-headed demon king of Lanka, and his wife, Mandodari. He is also known as Meghanaad (Thunderous) because his birth cry sounded like thunder.
Indrajeet plays an active role in the great war between Rama and Ravana in the Ramayana. Invincible because of the yajna (ritual penance) he performs before every battle, he defeats Rama once, and Rama’s brother Lakshmana twice.
On their third encounter, Lakshmana, with the help of Indrajeet’s uncle, Vibhishana, disrupts Indrajeet’s yajna, and after three days and three nights of fighting, finally kills him.
