So, since it looks like I'm not the only one who has it in his head to build a MG Full Armor ZZ using the MG FAZZ and MG ZZ, here's a breakdown of the parts you need to do it.

As I said in >>23397877 , the MG FAZZ includes almost everything from the Enhanced ZZ expansion kit, except for the waterslides and a single runner (the blue chest parts, two backpack beam saber sheath parts, and a single back skirt underlayer). If you think you can live without those, then you can save yourself $20-25 in a P-Bandai expansion kit (which hasn't been sold in the US since 2022). And if you think you can live with the wrong backpack and no beam sabers, then you can dispense with the MG ZZ too and just recolor the MG FAZZ.
