So, what you actually need are...
- Gold paint - any gold paint you like, shade doesn't matter, it's your call!
- 2 kits of HGUC 1/144 Banshee Norn Unicorn Mode (for the 2 closed armed armor DE)
- 1 kit of HGUC 1/144 Unicorn Gundam 03 Phenex ver GFT [you will need it for the v-fin] it came with 2, you can cut and fold the other one for Unicorn Mode!
- 1 kit of HGUC Banshee Norn Destroy Mode for the backpack connector if you don't have the Phenex - but then again, you will need the v-fin of the Phenex unless you want to scratch build it and having the NT-D Phenex is cheaper way to build both Destroy mode and Unicorn mode.
