Afterward, the party can use their best offenses to quickly dispose of the main body, which will not do much during the fight. The player should take care of the tentacles first.

Summoning Knights of the Round during this battle will give the main body of Bizarro∙Sephiroth an extra 60,000 HP and Safer∙Sephiroth an extra 80,000 HP. If the party completely depletes the HP of the main body and the two tentacles at once, they will receive all spoils. If the party kills the two tentacles during the countdown, they can still receive the AP from them. Once her health is below 15,000 HP, Jenova will count down from five, and upon reaching 0, she will cast Ultima as a final attack, and the party will gain no EXP or AP from the battle. Her Stop ability is used if part B is alive but part C is dead. Her Cure3 spell restores HP to all her allies at once and is used if part C is alive but part B is dead. Her Bio2 attack may poison to all party members, and she only uses it if both tentacles are alive. After both tentacles have been defeated, they will be revived to 25% of their maximum HP. She may inflict Fury with Repeating Slap when part B is alive. The tentacles will damage the party for around 1,500 points, along with possibly inflicting Sadness with Absorb this does not drain HP, and is only used if part C is alive.
