Sin (head)

The head of Sin, also known as Overdrive Sin, is a boss in Final Fantasy X, and is the last of the four-part battle against Sin. This time Sin will charge directly towards the player on their airship, moving slowly forward turn by turn while slowly opening its mouth. After about sixteen turns, Sin's mouth will open completely and it will use its Overdrive, Giga-Graviton, to completely destroy the player's party, resulting in an instant Game Over.

Strategy
For the first half the battle, Sin is out of range of physical attacks. Its only attacks, outside of the massive main attack, are status effect moves. Aeons' Overdrives are useful in removing his HP before Sin can destroy the player's party. If Lulu can do so, doublecasting Flare or Ultima is effective. Auron should use Armor Break to make Sin vulnerable to attacks, and Tidus should cast Hastega on the party and use Quick Hit, which can allow him several attacks in a row.

It is possible to end the battle quickly by having Rikku mix a Trio of 9999, wait until Sin is in range, and use multi-hit attacks on Sin, such as Tidus's, Lulu's or Wakka's Overdrives. A strong Anima's Overdrive can one-hit Sin.
