Once there was a king of evil from the kingdom of Iman Imantaka whose name is Niwata Kawaca. He was a powerful and cruel king who had conquered many kingdoms. The invincible king then had another ambition. He wanted to marry a beautiful angel from the heaven of god whose name is Dewi Supraba. He came to god Indra to propose for the beautiful angel. But the god refused. He thought that the king was not a good husband for the angel. The king was so angry that he decided to attack Kingdom of god Indra. The army of Niwata Kawaca proved to be very strong. The army of god was easily defeated. Luckily the god managed to close the gate. Then the god's palace was besieged by the army of Niwata Kawaca.
Then the god Indra decided to ask for help of human being. His choice fell into Arjuna, the third son of Pandu. At that time Arjuna was meditating in Mount Indrakila. He was meditating there to pray and to search for spiritual power that he needed to face the great war of Barata yudha (war of the Barata family). God Indra wanted to test his spiritual power to know whether he was fit for the battle with Niwata Kawaca. Indra sent seven beautiful angels to tease Arjuna. Two of the most beautiful ones were Supraba and Tilottama. They used their beauty to tease him but Arjuna was proved to be a true hero. He could resist their temptation. Indra was sure that Arjuna was the right person to overcome the problem.
Meanwhile King Niwata Kawaca realized that there was a hero who could be a threat to his power. That's why he decided to eliminate the potential threat. He sent a monster that could change himself into a wild boar. His name was Momong Murka. Momong Murka came to the village where Arjuna was doing ascetics. As he got there soon he changed himself into a giant wild bore and destroyed the village. Arjuna did not let him do further damage so he fought back. The wild boar was so strong that he was forced to use his new weapon. He attacked the wild boar with an arrow and it was killed instantly. But as he came closer to take a look at it he was very surprised to see another hero stood by it arrogantly.
Arjuna said politely:
'Excuse me; let me take a look at the wild boar. I just shot it with my arrow'
'Excuse me, did you shoot it? Look this is my arrow', the hero said.
'Of course I shot it. This is my arrow'
