Okay, I just found it!
Tachyon we need to change the profile! The Wundershatze is the one which you have pictured. Both of the Fighters are merely different colored versions of the Wundershatze as I thought. The "Cloudshazte", also known as the Speed Mirage is a different Mortar Headd, or "Air Headd" as Arart Ex calls it in volume 20.
I'll write up a profile of the Speed Mirage/Cloudshatze later. Hopefully we'll be able to get more info on it than just the fact that it transforms and has a Buster launcher.
As far as I know, there are no color pics of the Cloudshatze. However, the debut of the Cloudshatze in the manga (volume 20 english version) is very large and detailed...perfect for scanning. You just need to edit out the sound effects (which don't actually overlap the MH)
