The concept of Godzilla emitting U.V. spectra rather than radioisotope emissions would be fascinating. What if the forthcoming Toho Godzilla (Summer 2016, Japan) were a giant capacitor for energy derived from the sun? What a fascinating premise.
Based on this violet imagery, below (enhanced image from latest trailer), I am guessing that is where Toho is taking us this summer. I am glad that they are bucking the system a bit and taking this in different directions. From what I have read this is a reboot and does not assume any precedence or continuity with any of the legacy films.
