Final Fantasy X
Impulse is a rank 6 command ability used by Bahamut, which merely inflicts non-elemental damage to all enemies. It is also used as an enemy ability by enemy Bahamuts and Dark Bahamut. Dark Bahamut's version has the added effect of inflicting Petrify, which can shatter a character if it also KO's them. In addition to Petrify, it can also inflict Slow, Full Break, and Delay. Slow will ignore immunities to the status, but can still be countered via Auto-Haste.
