Safer∙Sephiroth Safer∙Sephiroth is the final boss in " Final Fantasy VII " . Being the last of Sephiroth ' s forms , this is his most powerful transformation . This battle is penultimate , but is considered the last challenge in the game , as it is followed by a plot - related battle that cannot be lost . The song " One - Winged Angel " plays during the battle against Safer∙Sephiroth ; a reference to Sephiroth ' s right arm being replaced by a single dark wing . Battle . Safer∙Sephiroth ' s base stats are listed in the table , but they change depending on many variables : Considering all these , Safer∙Sephiroth ' s maximum stats ( bracketed in the table ) are : Safer∙Sephiroth ' s attacks follow an eight turn cycle , allowing the player to predict his next attack and prepare accordingly . In all versions apart from the original Japanese version , the cycle is as follows : Safer∙Sephiroth ' s MP is restored to full at the beginning of every one of his turns , meaning he cannot ever run out . Safer∙Sephiroth ' s opening move is Wall , setting Barrier and MBarrier on himself . This cuts the damage the party does , so DeBarrier should be cast right away . He then casts Shadow Flare , a single - target attack capable of 7 , 500 damage against a level 65 character . Next he uses Pale Horse that is a single - target attack that inflicts some damage and always inflicts Sadness , Frog and Small , and a simple but powerful physical attack , which causes always Paralyze and Darkness . His other attacks he may use include Break , which is yet another single - target attack which may cause Petrify , a weak attack named Deen , DeSpell , and Super Nova , which is an attack that reduces the player ' s HP by 15 / 16 and may cause Confusion , Silence and Slow . Perhaps his most dangerous spell is Heartless Angel , which will reduce the HP of the entire party to 1 , but can be blocked and Safer∙Sephiroth will not use it until his HP is low . Furthermore , since it can never defeat the party and the player is likely to have a large number of Megalixirs thanks to the W - Item duplication bug , they can simply use Heartless Angel as a chance to heal up from the effects of Super Nova . Safer∙Sephiroth may rise into the air , becoming a Long Range enemy . He cannot be hit by close range physical attacks during this time , but is limited to using Pale Horse , Super Nova , Heartless Angel or Break . In the original Japanese version , the battle is slightly different . Sephiroth opens the battle with Slow instead of Wall and uses regular Flare instead of Shadow Flare . Pale Horse deals percentage based damage , and Super Nova , which as a different animation , does not deal percentage based damage , and can thus kill the party . In addition , Sephiroth will cast Doom in place of Heartless Angel . Strategy . As this is the final battle , the party should go all out with their best Materia and equipment . Ribbons are strongly suggested as Safer∙Sephiroth can inflict dangerous status effects . Mastered Restore and Revive Materia are also recommended and any Elixirs and Megalixir s can come handy . Level 4 Limit Breaks make quick work of Sephiroth , but are not necessary . The party should use Big Guard or Wall to stay protected . Safer∙Sephiroth ' s Super Nova charges the party ' s Limit Breaks quickly ; this is especially useful if the party has Level 4 Limit Breaks . If the party has Knights of the Round , the summon can kill Safer∙Sephiroth in a few uses . As all of Sephiroth ' s attacks , with the exception of Deen , either cannot KO the victim , or only hit one target , if the player is in great excess of Phoenix Down s , they can simply have one character attack , allow the second person to be KO ' d , and the third to use a Phoenix Down on the second . This can fail if Super Nova inflicts Confusion , or if Sephiroth gets enough turns to use Deen . Other appearances . " Theatrhythm Final Fantasy " .
