What a funny name. It says “Madrock” on the box but “Mudrock” on its base. This is your typical dated GFF with loads of details and one of many with the option to convert to another totally different (yet slightly similar) Gundam.
Posing on this figure is of course limited to basic movements and you should definitely watch out for impurities such as messed up paint and bent parts. I left it as the G05 because there’s more going on with it than the Mudrock.
