Hanuman is a monkey who initially serves Sugreeva. In his childhood, Hanuman's father told Hanuman to dedicate his life to serving Vishnu. Hanuman is the first monkey to realize that Rama is an incarnation of Vishnu, and in following his father's instructions, Hanuman becomes one of Rama's most trusted and loyal advisers. He's also an excellent judge of character; he correctly judges Vibishana, Ravana's brother, as being loyal to Rama's cause. Hanuman is also extremely powerful, though he's unaware of his powers for much of the story. When Hanuman is reminded of his great power, he finds he's capable of growing to a massive size and can step over the ocean in one step. He's tasked with finding Sita in Lanka, and keeps Sita from committing suicide out of despair. When Rama is finally crowned king in Ayodhya, Hanuman chooses to stay with Rama and serve him.
