Jatayu is a valiant bird in the legends that depicted it. In the Hindu epic Ramayana, Jatayu is an old friend of Rama. It attempted to rescue Rama's wife Sita after she was kidnapped by Ravana, the devil-king. A fierce battle ensued, but Ravana managed to defeat Jatayu by slashing its wings. In a Malay literature, Hikayat Merong Mahawangsa, Jatayu is the nephew of the giant bird Garuda. It was summoned by King Merong Mahawangsa, a friend of the prince of Rome, to rescue the prince's betrothed, a Chinese princess who was kidnapped by Garuda. Despite its determination, Garuda managed to overpower Jatayu.

"A king of the birds, appearing in the Indian epic "Ramayana". He takes the form of a vulture and was said to have lived for over 6,000 years. Although he is the son of Arna, brother of Garuda, another king of the birds, he is also sometimes considered the son of Garuda himself. In the "Ramayana", he forms a friendship with King Rama, an incarnation of the supreme Hindu deity Vishnu, and promised to protect Rama's queen, Sita. However, Sita was kidnapped by Ravana, king of the Rakshasas and an enemy of Rama. Jatayu set out alone to save Sita, but had his wings cut off by a sword and was mortally wounded. He died in Rama's arms."
Jatayu is hatched from an Egg, found in the Velg's Cave, the first dungeon of the game.

Jatayu is first encountered as a boss and accompanied by Garuda. Once the party has reached an elevation of 4,264 ft. they will come to an external area where the two can be seeing circling in the skies. Once the party has raised the third platform and reaches the end of the final bridge they will attempt to block their path.
Jatayu is fought first and will frequently use Mudoon and Mamudoon to attack. It will also typically respond to -kaja buffs and -nda debuffs as soon as possible with Dekaja and Dekunda.
After it is defeated Garuda enters the battle as a reinforcement.
