What is FAZZ?
What's?
A mobile suit created to evaluate the additional armor of the ZZ Gundam. The name "FAZZ" is a nickname given by those involved and the pilot for convenience, and is not its official name. The model number was also given for convenience after construction. (From Gundam Wiki)
This is the one I chose to build this time. Actually, I'm still in the middle of reading "ALICE's Confession," so I don't know what it does, but it's obvious that the design is cool. It's a product that's easy to see why it's a popular kit.
For details on the construction process, see the production notes.
