Weapons

A Weapon is any object used to inflict damage by either physical or non-physical (i.e. elemental) means. In Kingdom Hearts: Chain of Memories, all characters and enemies wield Cards.

Sora
Sora is the first playable Keyblade wielder in the series (by release date). Sora's weapons are all variations of his normal Keyblade with a relative appearance as to where he earned that Keychain, or who he obtained it from. It is noted that his Keyblade abilities become more advanced as the series moves on.

Donald
Donald uses staves, and these usually either increase attack (since Donald's is usually very low) or increase his magic proficiency.

Goofy
Goofy ironically uses shields, though he is the captain of the Disney Knights. His shields are usually either inclined towards strengthening his defense (typically the larger shields)or his attack (typically the smaller shields).

Organization XIII
All of the Organization's weapons below are featured in Kingdom Hearts 358/2 Days. The weapons featured in Kingdom Hearts II are noted as such.

Xigbar
Xigbar uses ranged weapons known as Arrowguns, a peculiar type of laser gun with traits similar to crossbows and handguns. Many of his weapons' names are based on demonic names and ranged weapon terminology, and several are named after enemies from the Final Fantasy series. Unlike other characters, his attacks have a much longer range and a slight homing ability. However, his attacks are limited by a number next to the "Attack" command. Once the number runs out, Xigbar must then reload, leaving him open for almost two seconds. Xigbar's joke weapons are Dryer and Trumpet, both still retaining the ammo limit and reload features of Xigbar's other weapons. If equipped with the Zero Gear, Xigbar can wield his Sharpshooter arrowguns from Kingdom Hearts II. Xigbar is able to combine his Arrowguns into a single sniper rifle, regardless of what model he is using.

His shield, Frozen Pride, has even been shown to have a health bar of its own in the data battle in Kingdom Hearts II Final Mix.

He can equip Frozen Pride with the Zero Gear.
