Ultima Weapon (SoM)

The Ultima Weapon (アルテマウェポン)' is a Keychain for Suné's Keyblade. It's the most powerful Keychain above all.

Design
Much like the first Ultima Weapon, it is a sword-like Keyblade covered with light blue filigree, like in the  version. The chain designs are, like in the Kingdom Hearts II version, three crowns connecting to a crown-and-heart Keychain. The teeth are in the shape of a crown and heart, as all Ultima Weapons have.
