Rakshasa

Brahmā, in a form composed of the quality of foulness, was produced hunger, of whom anger was born: and the god put forth in darkness beings emaciate with hunger, of hideous aspects, and with long beards. Those beings hastened to the deity. Such of them as exclaimed, “Oh preserve us!” were thence called Rākṣasas.[5] Those created beings, overwhelmed by hunger, attempted to seize the waters. Those among them who said—“we shall protect these waters”, are remembered as Rākṣasas.[6]

Rakshasas were most often depicted as shape-shifting, fierce-looking, enormous monstrous-looking creatures, with two fangs protruding from the top of the mouth and having sharp, claw-like fingernails. They were shown as being mean, growling beasts, and as insatiable man-eaters that could smell the scent of human flesh. Some of the more ferocious ones were shown with flaming red eyes and hair, drinking blood with their cupped hands or from human skulls (similar to representations of vampires in later Western mythology). Generally they could fly, vanish, and had maya (magical powers of illusion), which enabled them to change size at will and assume the form of any creature. The female equivalent of rakshasa is rakshasi.[7]

In the world of the Ramayana and Mahabharata, Rakshasas were a populous race. There were both good and evil rakshasas, and as warriors they fought alongside the armies of both good and evil. They were powerful warriors, expert magicians and illusionists. As shape-changers, they could assume different physical forms. As illusionists, they were capable of creating appearances which were real to those who believed in them or who failed to dispel them. Some of the rakshasas were said to be man-eaters, and made their gleeful appearance when the slaughter on a battlefield was at its worst. Occasionally they served as rank-and-file soldiers in the service of one or another warlord.

Aside from their treatment of unnamed rank-and-file Rakshasas, the epics tell the stories of certain members of these beings who rose to prominence, sometimes as heroes but more often as villains.

Thapar suggests that the Rakshasas could represent exaggerated, supernatural depictions of demonized forest-dwellers who were outside the caste society.[8]

In books 3-6 of the Rāmāyaṇa, the rākṣasas are the main antagonists of the narrative. The protagonist Rāma slays many rākṣasas throughout the epic, including Tāṭakā, Mārīca, and Rāvaṇa.[3] In the epic, the rākṣasas are portrayed as mainly demonic beings who are aggressive and sexual. They can assume any form they wish, which Rāvaṇa uses to good effect to trick and kidnap Sītā, Rāma's wife, which drives the rest of the narrative. The rākṣasas reside in the forests south of the Gangetic plain and in the island fortress of Laṅkā, both far away from the lands of Kosala and the home of Rāma. In Laṅkā, the capital of Rāvaṇa, the rākṣasas live in a complex society comparable to the humans of Ayodhyā, where some rākṣasas such as Vibhīṣaṇa are moral beings.[9]

Ravana the king of Lanka with ten heads, was the commander of Rakshasas.

Kumbhakarna

The Pandava hero Bhima was the nemesis of forest-dwelling Rakshasas who dined on human travellers and terrorized human settlements.

• Bhima killed Hidimba, a cannibal Rakshasa. The Mahabharata describes him as a cruel cannibal with sharp, long teeth and prodigious strength.[10] When Hidimba saw the Pandavas sleeping in his forest, he decided to eat them. He sent his sister Hidimbi to reconnoiter the situation, and the young woman fell in love with the handsome Bhima, whom she warned of danger. Infuriated, Hidimba declared he was ready to kill not only the Pandavas but also his sister, but he was thwarted by the heroism of Bhima, who defeated and killed him in a duel.
• Ghatotkacha, a Rakshasa who fought on the side of the Pandavas, was the son of Bhima and the Rakshasi Hidimbi, who had fallen in love with the hero and warned him of danger from her brother. Bhima killed the evil Rakshasa Hidimba. Their son's name refers to his round bald head; ghata means 'pot' and utkacha means 'head' in Sanskrit. Ghatotkacha is considered a loyal and humble figure. He and his followers were available to his father Bhima at any time; all Bhima had to do was to think of him and he would appear. Like his father, Ghatotkacha primarily fought with the mace. His wife was Ahilawati and his sons were Anjanaparvana and Meghavarna.

In the Mahabharata, Ghatotkacha was summoned by Bhima to fight on the Pandava side in the Kurukshetra War. Invoking his magical powers, he wrought great havoc in the Kaurava army. In particular, after the death of Jayadratha, when the battle continued on past sunset, his powers were at their most effective (at night). After performing many heroic deeds on the battlefield and fighting numerous duels with other great warriors (including the Rakshasa Alamvusha, the elephant-riding King Bhagadatta, and Aswatthaman, the son of Drona), Ghatotkacha encountered the human hero Karna. At this point in the battle, the Kaurava leader Duryodhana had appealed to his best fighter, Karna, to kill Ghatotkacha, as the entire Kaurava army was near annihilation due to his ceaseless strikes from the air. Karna possessed a divine weapon, Shakti, granted by the god Indra. It could be used only once and Karna had been saving it to use on his arch-enemy Arjuna, the best Pandava fighter. Unable to refuse Duryodhana, Karna used the Shakti against Ghatotkacha, killing him. This is considered to be the turning point of the war. After his death, the Pandava counselor Krishna smiled, as he considered the Pandava prince Arjuna to be saved from certain death, as Karna had used the Shakta divine weapon. A temple in Manali, Himachal Pradesh, honors Ghatotkacha; it is located near the Hidimba Devi Temple.

• Bakasura was a cannibalistic forest-dwelling Rakshasa who terrorized the nearby human population by forcing them to take turns making him regular deliveries of food, including human victims. The Pandavas travelled into the area and took up residence with a local Brahmin family. Their turn came when they had to make a delivery to Bakasura, and they debated who among them should be sacrificed. The rugged Bhima volunteered to take care of the matter. Bhima went into the forest with the food delivery (consuming it on the way to annoy Bakasura). He engaged Bakasura in a ferocious wrestling match, and broke his back. The human townspeople were amazed and grateful. The local Rakshasas begged for mercy, which Bhima granted them on the condition that they give up cannibalism. The Rakshasas agreed and soon acquired a reputation for being peaceful towards humans.[11]
• Kirmira, the brother of Bakasura, was a cannibal and master illusionist. He haunted the wood of Kamyaka, dining on human travellers. Like his brother before him, Kirmira also made the mistake of fighting the Pandav hero Bhima, who killed him with his bare hands.[12]
• Jatasura was a cunning Rakshasa who, disguised as a Brahmin, attempted to steal the Pandavas' weapons and to ravish Draupadi, wife of the five Pandavas. Bhima arrived in time to intervene, and killed Jatasur in a duel.[13] Jatasur's son was Alamvush, who fought on the side of the Kauravas at Kurukshetra.

Rakshasa heroes fought on both sides in the Kurukshetra war.

• Alamvusha was a Rakshasa skilled at fighting with both conventional weapons and the powers of illusion. According to the Mahabharata, he fought on the side of the Kauravas. Arjuna defeated him in a duel,[14] as did Arjuna's son Abhimanyu.[15] But Alamvusha in turn killed Iravan, Arjuna's son by a Nāga princess Ulupi, when the Rakshasa used his powers of illusion to take on the form of Garuda.[16] Alamvusha was also defeated by Bhima.[17] He was slain by Bhima's son, the Rakshasa Ghatotkacha.[18]
