Whishing Star

A very short Keyblade you'll get at Geppetto's house once you save him. aside from its bad range, it always finishes things with a strong critical blow.

Three Wishes

A swift Keyblade given when you've lock Agrabah's Keyhole. It's good at attacking before your foe defends them selves.

Lionheart

An amazing Keyblade given to you when you defeat Cloud and Leon at he Hades Cup. excellent for strong fighters and skilled magic users, the best for those who like magic that and close combat.

Lady Luck

A great Keyblade found some where in Wonderland.
It's twice as good as the Crabclaw, and gives you more MP.

Divine Rose

A skillful Keyblade given to you by Belle. It great for blocking enemy attacks, and has good offensive power to. A real good close combat weapon.

Crabclaw

A real good Keyblade given to you when lock Atlantica's Keyhole. If your really good with magic and head on attack, uses this Keyblade until later in the game.

Metal Chocobo

A strong, but not very powerful Keyblade given to you by Cloud when you defeat him in the Hercules Cup. It bad at Magic and making critical hit, so you wouldn't want to use it much.

Diamond Dust

Although it may seemed to have first appeared in Kingdom Hearts: Chain of Memories, it really first appeared in Kingdom Hearts Final Mix (which is only in japan). Its unknown to me on how to get in Kingdom Hearts Final Mix (since you can get it in Kingdom Hearts Chain of Memories by searching in Castle Oblivion later in the game), my guess is that you must defeat The Ice Titan at the Olympus Coliseum's Gold Match. This Icy foe will give you a hard time, be sure to equip Ice resistant items.

One-Winged Angel

Although it may seemed to have first appeared in Kingdom Hearts: Chain of Memories, it really first appeared in Kingdom Hearts Final Mix (which is only in japan). Its unknown to me on how to get in Kingdom Hearts Final Mix (since you can get it in Kingdom Hearts Chain of Memories by searching in Twilight Town later in the game), my guess is that you must defeat Sephiroth at the Olympus Coliseum's Platinum Match. Be warned, he's much harder than the final boss is.

Way to the Dawn

A powerful Keyblade Riku holds, it looks like his Soul Eater blade from the previous Kingdom Hearts games.
