Dragon Fang is the initial Overdrive ability for Auron. The input for it is ( in the Japanese and North American version). When successfully input, it will delay all enemies' turns. It is a Rank 5 ability.
Dragon Fang deals physical damage to all enemies, and temporarily lowers their Attack by a large amount. It's exclusive to Auron, requires one Soul Gauge to use, and is obtained via Shimmering Blade (X). The animation is similar to the original, Final Fantasy X version, however, Auron leaps to the middle of the screen, as opposed to simply jumping straight up, before slamming his blade into the ground.
