Vulcan Merge

The Vulcan Merge is a maneuver used by Decoe and Bocoe in the Sonic X anime series.

Description
The Vulcan Merge is a technique wherein in Decoe and Bocoe combine their bodies, although they both 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 Bazooka" from Decoe’s head.

It was shown to be powerful enough to break the steel bars of the cage the two robots and Eggman were in.
