Yuna, definetly Yuna. I hated her (im talking FFX here)

Pretty much every character from FFX-2, except for Paine, Buddy, and Gippal these were the only characters in the game i could stand.

Steiner he was just so annoying with his 3 common phrases of "Princess", "Thief", "Master Vivi" and live to serve attitude, also the constant clinking of his suit alone was annoying enough.
