Tyrant is an enemy in Final Fantasy XIII. When first encountered in Taejin's Tower, they can be difficult because of the Centaurion Blade they create. It is recommended to start the battle with a preemptive attack to stagger the Tyrant so it cannot forge a Centaurion Blade. A good setup is COM/COM/RAV with Lightning, Fang and Hope or use RAV/COM/SYN to buff the party with defensive and offensive spells if the party cannot defeat it in one stagger.
