Desperation attacks [ffvi]

[Yuffie Kisaragi]

This info is from Final Fantasy Wiki (I can't post all the info because the chart doesn't show up properly on the forum):

A Desperation Attack is a special attack unique to each character in Final Fantasy VI. When a character is in Critical Status, there is a 1 in 16 chance that the character will perform this move when he or she uses the Fight command. A character would automatically enter Critical Status when their HP drops to 1/20 of their max. It is important to note that Strago Magus and Gogo can achieve Critical Status without losing their HP. If the enemy has 1/20 of its max HP remaining, Strago and Gogo can use Rippler to retrieve it (see Rippler Bug for more information). All Desperation Attacks are unblockable and defense ignoring. Each character's Desperation Attack is as follows:

Character: Terra
D. Attack: Riot Blade

I've only ever got Terra's and Locke's desperation attacks, often come up as lifesavers on bosses if i'm staying weak for the stronger espers.
