Bizarro∙Sephiroth Bizarro∙Sephiroth is Sephiroth ' s first form in the final battle of " Final Fantasy VII " . It is a grotesque form of Sephiroth with multiple body parts acting independently of one another . Mechanics . The way the player fights Bizarro∙Sephiroth changes depending on their actions in the previous battle against Jenova∙SYNTHESIS , the average party level , and whether or not the player has obtained Yuffie and Vincent . When certain criteria is met , the game will ask the player to select either one , two or three parties ( one set of three , two sets of three , or two sets of three and one set of two ) to fight Bizarro∙Sephiroth with . To qualify for a one party situation , one of the following conditions must be met : To qualify for a two party situation , the player must not qualify for a one party situation ( see above ) . In addition , one of the following conditions must be met : To qualify for a three party situation , the player must not qualify for one or two party situations . Specifically , all of the following conditions must be met : When dealing with two or three parties and switching between them in battle , the HP values of all of the parts are saved for that particular party only . For example , in a two - party situation , the Head Part can have different values of HP for each party . The single party version of Bizarro∙Sephiroth is the easiest , as he has the lowest amount of HP for all of his parts . The two party version requires a different strategy as the two parties must defeat both the Left Magic and Right Magic parts of Bizarro∙Sephiroth before the Core is vulnerable . The three - party version requires more strategy between each party as the primary goal is to defeat two of the sub - Cores so the main - Core becomes vulnerable to attacks . Thus , the parties surrounding the main party ( Cloud ' s party ) must defeat the Left and Right Magic Part to make their relative sub - Core vulnerable . After this is achieved , Cloud ' s party can attack the main Core and finish the battle . Battle . The statistics vary based on various things the party has done before the fight commences . Bizarro∙Sephiroth ' s base stats are listed in the table , valid for the one party battle and the main battles for two or three parties . Aeris is not counted , so even if she reaches level 99 , it will not affect Bizarro∙Sephiroth ' s HP . Bizarro∙Sephiroth ' s limbs can use powerful magic , but they have low HP . Once alone , the body will often heal itself for upwards of 6 , 000 HP with Bizarro Energy . It can attack the party with Stigma which always inflicts Poison and Slow and a single party member with Sephiroth Shock , but neither attack is too strong . His Aurora Fence attack revives and magically restores HP on all opponents . Game signals a " Miss " on targets who are not under KO status , but actually removes all status effects on all opponents , whether they are under KO status or not . Only the Core and Body have turns . The Core will use Bizarro Enegy [ sic ] to restore 7000 HP to the Body , which attacks . The battle ends when the Body is destroyed , and the Core is invincible until the Magics are defeated . The Magics and Head modify the attacks the Body uses ; without them , the Body uses regular attacks and Heartless Angel only . Only the Head can regenerate when destroyed . Bizarro∙Sephiroth ' s Head ' s and Body ' s MP are restored to full at the beginning of every turn . When killed , the party fights Safer∙Sephiroth next . Strategy . A few casts of Ultima , or a summon or two of one of the Bahamut summons , can destroy Bizarro∙Sephiroth ' s limbs , leaving only the core and the body . The Enemy Skills Aqualung and Pandora ' s Box can hit the Magics , the Head , and the Body for big damage without being absorbed . The player can use them to quickly eliminate all parts of Bizarro∙Sephiroth with the exception of the Body . The party should use Big Guard , and Regen or Cure3 to heal while attacking the body . The Head will regenerate , but it can be killed again easily . As long as the player kills off Right Magic and Left Magic , Bizarro∙Sephiroth is not too difficult to beat . Alternatively , the Core and the Body can be killed instantly using the Enemy Skill Roulette , which it is not protected against , though it is a gamble . Another easy way to end the battle is to summon Knights of Round . Musical themes . " Birth of a God " is the fifteenth track of the fourth disc from the " " . The penultimate battle theme , it is played during the fight against Bizarro∙Sephiroth . Sephiroth ' s " de jure " theme " Those Chosen by the Planet " is mixed into this piece .

It appears in " Final Fantasy VII " in the boss names of Jenova ' s parts and Sephiroth ' s boss forms .
