Dyne (裏技 Urawaza) is Zidane's Trance skill in Final Fantasy IX. Each Dyne corresponds to one of his Skills, and will be available for use during Trance only when Zidane can use the corresponding Skill. All Dynes are physical attacks that target either one or all targets.

In Dissidia Final Fantasy, all of Zidane's HP and Brave attacks are based on his Dyne techniques, though some function and appear differently than they did in Final Fantasy IX - Grand Lethal, for example, has Zidane charging inside a series of energy beams, rather than releasing them from his body and Shift Break has an addition of lightning columns, mostly in order to contain the opponent so the final blast of water hits.
The Japanese name for Dyne, urawaza, translates to "underhanded tricks".
The Dyne is also a somewhat obsolete unit to measure forces. It is the force required to accelerate a mass of one gram at a rate of one centimeter per second per second, which in SI-derived units is exactly 1·0×10-5 Newtons (10μN).
