Klikk

Klikk is a boss in Final Fantasy X, fought early in the game when Tidus is trapped in the underwater ruins, later identified as Baaj.

This boss battle is the first time the player is in danger of receiving a Game Over, and also the first time where AP and gil are earned after victory. Tidus will seem to be hopelessly outmatched against the fast-moving fiend, but when it's HP drops to half, a group of eccentrically-dressed individuals will bust into the hall and their leader will quickly join the battle. A tutorial begins to explain two special skills available to ????: Steal and Use. By this time Klikk will have returned to full health, but by having ???? steal and throw Grenades, the battle will be easily won. Tidus can now be used to deliver a few sword strikes (and an Overdrive if and when one becomes available), and to use a potion or two if necessary.

After victory, Tidus will be grateful to his newfound comrades, but apparently they are not as hospitable as he thought. ???? will deliver a nice sucker-punch to Tidus' stomach and he will promptly black out.
