Yes.
He wouldn't even have to use KOR instead he can just omnislash her. Ultimecia is a joke when it comes to the final boss because she is so simple.
Totally.
Its possible this can be tested in dissidia final fantasy for the PSP.
In a hypothetical battle, the Knights of the Round from Final Fantasy VII would likely have the advantage over Orphan from Final Fantasy XIII. The Knights are powerful summon creatures with high damage output and various elemental attacks, while Orphan, despite being a formidable foe, has specific weaknesses that can be exploited. Additionally, the sheer number of Knights summoned would overwhelm Orphan's defenses. Ultimately, while both are strong, the Knights of the Round possess the potential to defeat Orphan in a direct confrontation.
Knights of round
Yes.
Knights of the Round summon from FFVII as it does the most damage any summon will ever do if it's maxed out doing 13x 9999 damage.
Yes, nothing else will do. You cannot reach the island in which it is kept any other way. However you can defeat Emerald Weapon and trade the Earth Harp you receive to a man in Kalm, and he will give you three Master Materia, the summon one will allow you to cast Knights of the Round, though you won't have a separate Knights of the Round materia.
Kefka and Ultimecia are two separate villains from two separate games Kefka is the main antagonist of Final Fantasy VI and Ultimecia is the main antagonist in Final Fantasy VIII.
1 hit from knights of the round will do it
Either but i would say Knights of a round, for damage reasons even though it takes forever to charge.
Ultimecia did not give birth to Sephiroth; they are from different game universes. Ultimecia is a character from "Final Fantasy VIII," while Sephiroth is from "Final Fantasy VII." Their stories and origins are distinct, with Sephiroth being born from the character Lucrecia Crescent, and Ultimecia being a sorceress from the future. Therefore, there is no connection between them regarding parentage.
