The Vulcan Merge (バルカン合体 Barukan gattai?)[1] is a move that appears in the anime series Sonic X. It is a technique used by Decoe and Bocoe where they combine to form a powerful weapon.


The Vulcan Merge is a technique wherein Decoe and Bocoe combine their bodies, although they still maintain their separate conscious. It starts by Decoe extending his body while retracting his arms in. Bocoe then stretches his arms and extends them upwards for Decoe to fall on. Decoe then inserts a head plate from his chest onto Bocoe’s head before firing an attack named the "Decoe-Bocoe Brain-Bazooka"[2] from Decoe’s head. This shot is powerful enough to break the steel bars of a cage.
