The Garren Buckle (ギャレンバカル Gyaren Bakaru) is the transformation device that Sakuya Tachibana uses to become Kamen Rider Garren. It was designed for specific compatibility with the ♦A: "Change Stag" Rouse Card and harnesses the DNA of the Stag Undead. This model utilizes the "Turn Up" mechanism (similar to the Blay Buckle) to produce a stationary transformation screen, which initiates the fusion of Undead DNA with a human to produce the Kamen Rider transformation. Coincidentally, the transformation screen itself can act as a deflective wall against assaults.
- During its usage in Super Hero Taisen GP: Kamen Rider 3, the transformation screen produced by the Garren Buckle moves towards the user much like the screen produced by the Leangle Buckle. The reason for this is unknown.
