We had this fun GB in 2009, a group build of RX-178 MKII.
The theme is to give the MKII a mythical code name, though I should have, but we didnt set which race's myth.
Mine is Athena, the Goddess of Wisdom. so the MKII i build basically is a mecha for infiltration and information & data spy. The weapon it carries is minimal, and just like Athena/Athene, it has a powerful shield to protect it from attacks. The red thing i made for this gundam is a energy shield generator, which exist all overall athena's body.
For workmanship, just basically some detailing n test with loads of metal parts. other than that is just standard gundam color spraying n flat top coat.
