Hanuman
Hanuman is the Hindi diety who aided one of the avatars of Vishni (Rama), assisting in the rescue of Rama's wife, Sita, from Ravana, king of the Rakshasas. He symbolizes the pinnacle of selfless and loving devotion (bhakti) as well as the indomnible bravery of the morally upright individual. Hanuman is the child of Anjana (who was a celestial being once upon a time before she was cursed and turned into a monkey) and a chance encounter with the Wind-God Vayu Deva (who blew her clothes off and, seeing her naked, had to have her). The child of their union is the morally upright Hanuman who inherited his father's godlike abilities of strength and flight.
He gets his name from the marks on his cheeks (hanuhH is Sandskrit for 'cheek') which is the scar left by Indra's Thunderbolt. When Hanuman was young, he mistook the sun for a piece of fruit and leaped into the sky to grab it. Indra, the chap who maintains the balance of the universal laws, zapped the young monkey with his Thunderbolt as he reached for the sun. However, after Dad made the long face, Indra capitulated and retrieved his Thunderbolt, letting the monkey child go free with just a scar to remember his transgression.
Brahma later made Hanuman diamond-hard, invincible to all weapons and attacks, and gave him immortality. This deathlessness (a state making him a chiranjeevi) also allows him to leave his mortal body whenever he chooses to flit about and do the things one does while astral (icchaa maranam -- dying at will). His monkey spirit makes him forget this detail at times and he has to be reminded of his invincibility by others.
