Angada
Angada is a vanara who helped Rama find his wife Sita and fight her abductor, Ravana, in the Ramayana. He was the son of Vali and Tara and the nephew of Sugriva. Angada and Tara are instrumental in reconciling Rama and his brother, Lakshmana, with Sugriva after Sugriva fails to fulfill his promise to help Rama find and rescue his wife. Together they are able to convince Sugriva to honor his pledge to Rama instead of spending his time carousing and drinking. Sugriva then arranges for Hanuman to help Rama and organises the monkey army that will battle Ravana's demonic host.
