Developed using the AMS-119 Geara Doga as a base, the main mobile suit of the anti-federation terrorist group Mufti featured in Hathaway's Flash—the Me-02R Messer—joins the HGUC model kit series following Penelope Gundam! Its bulbous structure features various articulation points to allow dynamic action poses (despite its girth).

This set includes pieces to build its beam rifle, shield, and 2 beam sabers.
