saix's weapon in kingdom hearts
Saix uses a massive blade called a Claymore. His main Claymore is named "Lunatic" Despite many dissimilarities to real claymores, Saix does use a very large, two-handed bladed weapon. His Claymore is decorated with many additives that resemble the Nobody logo, in blues and yellows. When in normal form, Saix attacks with powerful slashes and combos with the bladed edges. Although it seems to be a completely different weapon, the Cursed Hammer of the Berserker Nobodies is used in much the same way, and even has the same Reaction Command. The names of Saix's various claymores are all references to astronomy or astrology, especially the moon.
In history, a Claymore refers to the Scottish variant of the late medieval two-handed long-sword. It is characterized as having a cross hilt of forward-sloping quillons with quatrefoil terminations. It was in use from the 15th to 17th centuries. The term claymore is an Anglicization of the Gaelic claidheamh mor "great sword", first attested in 1772 (as Cly-more) with the gloss "great two-handed sword."
The Lunatic has a smooth, white handle with a grey spike set in its pommel. The guard is a pale yellow semi-circle with four small notches in its outer edge. The lower part of the main blade is thick and has concave sides, each side being lined by three small notches. The blade is pale blue and has blue-grey edges. The lower half of the blade is decorated by two small, light blue diamonds. The tip of the Lunatic is a blue ring with dark-blue edges and lined by seven spikes. The tip is connected to the main blade by a pale yellow symbol shaped like the top half of the Nobody logo.
When Saix enters his berserker state, the tip of the Lunatic is divided into two large, identical halves, each with three complete spikes lining the outer edge. These halves also gain four enormous, pale blue spikes shaped like those on the Nobody logo. The two halves retain the coloration of the normal Lunatic and are connected to the main blade by the cross-shaped symbol, which has become slightly larger. The word "lunatic" comes from the belief that the moon induces madness, much like Saix's Berserker state is entered with the moon's power.
