Safer∙Sephiroth

Safer Sephiroth is the final boss in Final Fantasy VII, and Sephiroth's ultimate form. This is his final transformation in anticipation of becoming a god. Although there is one last fight with Sephiroth after this, it is virtually scripted and is not usually counted as a battle by those who have played the game. The iconic song One-Winged Angel is played during the battle, referring to Sephiroth's right arm being replaced by a single dark wing.

Safer Sephiroth's base stats are listed in the table, but they change depending on many variables:
 * Each character at Level 99 (not counting Aeris) adds 30,000 Max HP, 2 Attack, 20 Def, 5 Magic and 16 MDef
 * Casting Knights of the Round on Jenova SYNTHESIS adds 80,000 Max HP
 * Any time Bizarro Sephiroth's head was killed during the previous fight reduces 100 Max HP up to a maximum reduction of 24,900 HP

Considering all these, Safer Sephiroth's maximum stats (within brackets in the table) are:
 * 400,000 Max HP, 246 Attack, 260 Defense, 140 Magic Power and 308 Magic Defense (although it is practically impossible to cast Knights of the Round without killing the head)

Strategy
As this is the final battle, the party should go all out with their best Materia and equipment. Ribbons are strongly suggested as he can inflict dangerous status effects. Mastered Restore and Revive Materia are also suggested, if you don't already have them. Stocking up on Elixirs and Megalixirs is a good idea if you want to play it safe. Level 4 Limit Breaks make quick work of Sephiroth. It's a good idea to be at Level 50 or higher, but it's in no way necessary.

Safer Sephiroth's opening move is Wall, setting Barrier and MBarrier on himself. This cuts the damage the party does, so this should be DeSpelled right away. He can then cast Shadow Flare, which is a powerful singe-target attack, Pale Horse, which is a less powerful powerful single-target attack that may inflict status, and a simple but powerful physical attack, which also causes status effects. His other attacks he may use include Break, which is yet another single-target attack with a status-effect attached, a weak attack named Deen, Dispel, and Super Nova, which is an attack that reduces the player's HP by 15/16 with even more status-effects attached.

Perhaps his most dangerous spell is Heartless Angel, which will reduce the HP of the entire party to 1, but can be blocked and isn't usable until his HP is low. If hit with Heartless Angel, heal right away.

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.

The party should use Big Guard or Wall to stay protected. Sephiroth's Super Nova spell will charge the party's Limit Breaks very quickly, letting the characters unleash them quite often. Again, this is useful if you have Level 4 Limit Breaks, as they make quick work of Sephiroth. If the party has Knights of the Round, the summon can kill Safer Sephiroth in a few uses, if not on the very first use.
