Carbuncle* - "Ruby Light"
Moogle - "Moogle Power" (they arent gods)
Sylph - "Whispering Wind"
Golem - "Earthen Wall"
Chocobo - "Chocobo Kick"
Cait Sith (Stray) - "Cat Rain"
Unicorn - "Healing Horn"
Typhoon - "Disintegration"
Cactuar - "1000 Needles"
Magic Pot - "Item Mugger"
Tonberry - "Murderous Thrust"
Phoenix - "Rebirth Flame" (i vote this for 15 minutes ability for mega raise or something like that)
Angelo - "Angelo Rush", "Angelo Cannon", "Angelo Strike", "Angelo Recover", "Invincible Moon", "Angelo Reverse", "Angelo Search", "Wishing Star" (this would be awesome XD)
Moomba - "MoombaMoomba"
