Either but i would say Knights of a round, for damage reasons even though it takes forever to charge.
Knights of round
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.
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.
Yuna is in final fantasy 10 and can summon monsters like ifrit and shiva. She is also in final fantasy 10-2.
Shiva
Yes.
Yes.
Yes well this is my opinion. Final Fantasy X is better than Final Fantasy XIII
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.
I suppose so. Why not give it a try.
crisis is better
1 hit from knights of the round will do it
