Here's my 1/100 GN Exia Model kit cosplaying as it's battle damaged mode in the first episode of Gundam 00's 2nd season..
some parts were manually modified with use of modeling tools and the other cosmetics such as the eyes and burn damages were Photoshopped
The cape covering what used to be the arm belongs to My 1/100 MG Crossbone Gundam X-1 Ver. KA
This model Kit can still revert back to it's normal form
the head was really purposedly damaged to give it the authentic terminator-ish look. I was lucky to have an extra head thanks to the 1/100 Astraea Type F kit
with an extra exia head
