Sugriva

Second King of the monkey kingdom Kishkinda. Son of Surya. Brother of Vali, married with Ruma.

When the demon Mayavi was destroyed, the two brothers misunderstood. Vali pursued the demon into a cave and asked Sugriva if blood came out of the cave, then he would be dead and Sugriva should return to Kishkinda and crown himself king. When blood came out of the cave, Sugriva did as he was told. Vali, however, had killed Mayavi and resented his brother’s actions. Vali was later killed by Rama and Sugriva became king.

Vali was reborn as hunter Jara and killed Krishna.
