From Mobile Suit Gundam SEED Destiny anime, this is 13 MBF-P01-Re2 Astray Gold Frame Amatsu Gundam 1/100.
In the anime series Gundam SEED Astray, the Orb Union’s Morgenroete corporation built three Gundam Astray prototype mobile suits at Heliopolis, the MBF-P01 Astray Gold Frame, MBF-P02 Astray Red Frame, and MBF-P03 Astray Blue Frame,which in turn were used to base the five GAT-X series units that they assisted the Earth Alliance’s Atlantic Federation in creating. They successfully copied the EA’s beam rifle and saber technology, but Morgenroete did not have access to the Phase Shift armor design, and compensated by making the Gundam Astray units lighter and more agile than their EA counterparts. The Gold Frame, unlike the other two, was fitted with both Orb and Earth Alliance style hand plugs, allowing it to use the beam weapons of both nations. See details
