The AEUG's first original mobile suit design, taking in traditional aspects of Zeon MSs and pioneering new solutions such as the 360 degree monitors and the ejectable head-mounted cockpit.
A red unit was initially piloted by Quattro Bajeena, which sparked the fear of The Red Comet of old in the Titans; once the AEUG became aware of this, all subsequent Rick Dias units moved on from the old black and grey (resembling a Dom) to the new red, so as to capitalize on the psychological impact of the color.
