The one who attacks Junon is just WEAPON. He is the only one with 'weapon' captialized. All the others say 'Weapon'. People just decided to call him Sapphire because he's blue.*exasperated sigh*

Also, the Weapon on the moon isn't Omega! It's Cheese Weapon! Silly Goose!

The one beneath the swamp is Onyx Weapon! Get it right! And you don't need a red chocobo. You need a Rainbow one! You can get one by defeating Joe 100 times.
