This is the Gyan Vulcan, made using the HGUC 197 Gyan and the Variable Pod.

The Variable Pod is compatible with the HGUC 002 Gyan, but requires modification to attach to the newer one. This time, I went with the easier method of just drilling holes.

This means that the shoulder armor will be missing when using the Variable Pod, but if you're not going to display the pod on its own anyway, this is probably the better option.

For the less easy method, you'll need to enlarge the holes in the inner parts of the Gyan Vulcan's shoulder armor or make a U-shaped cutout, and also extend the Gyan's shoulder joint.
