Desperado (Feral) Chaos is an extremely hard battle - but not impossible.
Firstly - your party.
I would recommend:
Either Zidane or Kuja.
Any of Terra, Jecht, Exdeath, Warrior of Light.
Other useful characters: Lightning, Yuna, Tifa, Prishe, Sephiroth, Onion Knight, Squall, Cloud of Darkness, Emperor.
This was my party:
Kuja, Terra, Lightning, Kain, Warrior of Light.
Explaination:
Kuja is my favourite character for 2 primary reasons:
1) He doesn't need to be anywhere near you to hit you with powerful HP attacks
2) He is very hard to hit. He can glide and can move while using almost any attack meaning you can apply pressure with attacks and set yourself up from a comfortable distance for another attack.
Terra:
1) Meltdown can do strong tracing - for a long time.
2) Tornado keeps a safe distance and is lethal.
3) Strong attacks all round and good chains (Ultima, Firaga)
Lightning:
1) Powerful and very quick.
2) Strong BRV attacks
3) Can add BRV without even being close (Cure and Cura)
Kain:
1) Mainly because he is in my opinion just immensely strong and hard to kill but I only used him for the manikins in the gateways.
Warrior Of Light:
1) Shield of Light can save your life!
2) BRV attacks chain into strong HP attacks (Bitter End & Rune Saber).
Tactics:
Kuja up first.
SPAM ON ULTIMA!
If Chaos gets too close then Force Symphony or Flare Star.
Whatever you do - stay in the air and constantly move about. DON'T BOTHER WITH BRV ATTACKS!
I killed Chaos with just Kuja without losing 1 HP. believe me with Kuja - its easy.
Zidane:
Similar tactics and use Shift Break rather that Ultima and grand Lethal rather than Force Symphony/Flare star.
Terra/Jecht/Exdeath/Warrior of Light:
Go on defensive first:
Terra: Tornado
Jecht: Jecht Block & Trimuphant Grasp to get out of trouble.
Exdeath: Omni-Block
Warrior of Light: Wait for a BRV attack or a rush and then Shield of Light.
Continue and when Chaos's HP is low start offensive:
Terra: More Tornados & Fire>Firaga & Meltdown
Jecht: Jecht Beam & Ultimate Jecht Shot & Jecht Blade.
Exdeath: Delta Attack and follow ups to blocks.
Warrior of Light: Ultimate Shield and Shield of Light.
You dont.
u cant
can't unless you hack the psp
No, it's a summon exclusive to Chaos, normal characters can't get it unfortunately.
Dissidia, because you can beat Kefka in the face with Squall's Gunblade.
Dissidia FF 012 would be better because it's the sequel to Dissidia FF. It includes all the characters Dissidia FF has and more, as well as new costumes, new stages, and the ability to play as the Chaos characters in story mode. Dissidia only let you play as the Cosmos characters in story.
first go to 023 and beat gigls
Try it in dissidia.
What can beat the replica of dark magician of black chaos
there are none because you can't play as chaos. however, in the PP catalog, you can buy him as an opponant in quick battle. and yes, you still have to kill him 3 times. Signed, Phoenix
how do you beat blue rabbit's climate chaos
there is no one main character. but i suppose if you wanted to get technical, it would be chaos and cosmos. Signed, Phoenix
