Sephiroth swings his sword forward, catching up to three opponents. A cutscene initiates in which he transforms into Safer Sephiroth, followed by summoning a meteor that passes through a planet and into a star, causing the star to explode and destroy an Earth-like planet. The trapped opponents are then launched.
The move has a random effect on each opponent it launches (acting similar to Negative Zone from Brawl). In addition to dealing a total of 32% damage, each will suffer from one randomly chosen "debuff":
The sleep, reverse, and shield break results cannot occur on opponents that were offstage when the move began; however, they can still occur in the air.
Safer∙Sephiroth is the form that Sephiroth takes during the third phase of the final battle in Final Fantasy VII. This is the body that Sephiroth was creating for himself in the Northern Cave, as part of his plan to wound the Planet with Meteor, bait the lifestream into emerging to heal the wound, and merge with it to become a god. Despite this being the second-to-last phase, Safer∙Sephiroth is considered the final challenge of the main story, since the fourth phase pits Cloud against a metaphysical Sephiroth in a cinematic battle that cannot be lost.
Supernova, formatted as "Super Nova" in Final Fantasy VII, is Safer∙Sephiroth's ultimate attack. The Final Smash is a heavily-abridged recreation of the move from the international version of FFVII, which has become infamous for its ability to draw the battle out: it has an excessively long and elaborate animation (taking a full two minutes to execute), Sephiroth can use it multiple times during a battle, and it causes the player to sit through the animation of their party's health dropping, which can take a significant amount of time when they have reached their level cap. The move involves summoning a meteor to ravage the galaxy and turn the Sun into a supernova that engulfs the Planet, dealing fractional damage equal to 15/16 of the party's current HP and inflicting random status ailments on them. The original Japanese version of the move has a very different and much shorter animation (clocking in at 20 seconds), and it deals non-fractional damage, making it possible to wipe out the party.
The Final Smash is able to trap up to three opponents at once, referencing the number of available party member slots in Final Fantasy VII; when the move is activated, the three trapped players will face Safer∙Sephiroth, as the party does in the boss battle.
