The Amazon exclusive Skylanders Giants figure is called Gold Flameslinger. As the name he has been painted all gold from head to toe. The paint job makes sense considering the character shoots flaming arrows from his bow. He's a Series 2 figure and compatible with both the original Skylanders and Giants on Xbox 360, Playstation 3, as well as Nintendo Wii, Wii U and 3DS.
Amazon is selling Gold Flameslinger at the time of this post for $9.99. However, he could go out of stock any moment and then will only be available via the secondary market. There's no telling right now how many of these Toys for Bob made, or whether they will be restocked again.
If you're looking to fulfill the "gold" portion of "silver and gold" for Christmas, go grab a Gold Flameslinger while he is still on sale.
