All for One (オールフォーワン Ōru fō Wan) is a Keychain for Sora's and Riku's Keyblades that appears in Kingdom Hearts 3D: Dream Drop Distance. It is obtained after clearing Country of the Musketeers.
The Keyblade is primarily based off the Musketeers' rapier, while the teeth are the golden Musketeer fleur-de-lis emblem, and the hilt is Mickey's hat. The blue band on the hat extends outwards to form the guard. The handle is colored a light brown, as part of the rapier blade, while the chain is yellow and the Keychain is Mickey, Donald and Goofy's rapiers placed together to form a triangle.
