Normal: "An enormous bird found throughout Spira. It beats its giant wings to send shock waves crashing into enemies. It's said to be strong enough to carry a Behemoth off in its talons." Oversoul: "Flaps its wings with greater force now that it's oversouled. So much force, in fact, that one flap will send your Potions flying!" — Scan
The Shantak is an enemy from Final Fantasy X-2. It is a strong enemy at the start of the game but is relatively easy late in the game. It is much more difficult when in Oversoul due to the Chicken Wing attacks, but is still possible to defeat with ease. Use the strongest attacks the party has at the time to take it down.
In the Fiend Tale endings, a notable Shantak was created from the spirit of an Al Bhed who was among the pioneers in hovercraft development a century ago. Dying while piloting the prototype in the Calm Lands, his disappointment of not achieving flight resulted in his fiend. After gaining the hang of his ability to fly, Shantak returned to the Calm Lands and departed to the Farplane after flying across the area.
