Upon activation, a text box with the word Omnislash appears at the top of the screen as Cloud says ツキがなかったな。( Tsuki ga nakatta na, "Your luck runs out."). In a similar manner to Marth and Lucina's Critical Hit, he will rush forward and stop at the first opponent he encounters, and launches them or any other fighters in the vicinity to the stage's middle with an upwards swing. Cloud then proceeds to slash at the opponent repeatedly before slamming them downward into the stage, dealing a great amount of vertical and slightly sideways knockback. Omnislash deals a total of 50%, while opponents who were not caught but too close to the final explosion will be inflicted between 10%-14% damage depending on their distance from Cloud. The combination of large amounts of knocback and damage means this attack KOs very early.
Even though Cloud surrounds himself in the blue aura that is seen while in Limit Break status, Omnislash and Limit Break do not affect each other, with the aura being an aesthetic effect due to the Final Smash itself being a Limit Break.
Because Cloud rushes forward to initiate Omnislash, the Final Smash is considerably easier to land than other trapping Final Smashes. However, it can be avoided by jumping, as Cloud cannot connect with opponents who are too far away vertically.
Omnislash first appears in Final Fantasy VII as Cloud Strife's LEVEL 4 Limit Break learned from the Omnislash item of the same name. The item can be bought at the Battle Square in Gold Saucer by using Battle Points, and is available as soon as the player obtains the Tiny Bronco, although it will be cheaper if obtained in later discs. Cloud can learn it once he has learned all of his other Limit Breaks. Omnislash hits random enemies 15 times under the effect of automatic critical hits for 0.75 times normal damage each hit.
Even if the player doesn't learn Omnislash, Cloud will still have it during the final confrontation against Sephiroth (though he will not perform it if Sephiroth attacks first and Cloud's counter is coded to defeat Sephiroth regardless of if the attack damages or somehow heals Sephiroth.) This battle uses a different battle model for Cloud, making Omnislash look slightly different.
- Omnislash bears a striking resemblance to other Final Smashes, most notably Great Aether, Pair Up, Omega Blitz, Secret Ninja Attack, and Ultra Sword.
- The number of hits Omnislash in Smash Bros. does is exactly the same number of hits as in Final Fantasy VII.
