Elementary particle control beam

The elementary particle control beam (素粒子コントロール光線 soryūshi control kōsen) is a beam that is able to shrink Transformers down to smaller sizes and back to their original form. Although the name suggests wider usage, such is the only power it is demonstrated to have. Elementary particle control beam technology is installed in the "eyes" of the Galvaburg II, from where it can be shot down on any target.
