On the show, you'll notice that Rainbow Dash is, pretty much, the only rainbow-haired pony. But there was a whole set of them at one time. These ponies are Starshine and Sunlight. Yes, Sunlight's color scheme matches RD's almost to a T, minus the fact her hair doesn't have quite as many colors, and her eyes are purple. Her cutie mark is oddly similar, too- two golden clouds, with a silver sun behind them.There are so many old MLP toys out there, there's a site for them. I love going on their and redrawing them.EDIT- I made another one, but with Pinkie Pie! [link]
