Quillfire has a brother now. Scatterspike is repainted version of Quillfire, and he turned out great. In the RiD line, there are generally straight repaints, as opposed to the Generations line that at least gives a new head sculpt.
Scatterspike is sporting a darker color scheme with burgundy and purple. The bottom of his mouth is colored with a darker shade of grey more like a gunmetal. It is the only place that the color shows up. With Quillfire, his quills were the same color, so the color matches front to back. With Scatterspike, Hasbro focused on the secondary color of purple a lot more. You know purple is the color of Decepticons, so you know he is a bad guy.
From there, things continue to be the same. He has a blaster, which is still really cool, and fits his hand very well. It is the primary color of burgundy. He also has a removable spike that is in the purple color.
Side by side in vehicle mode, I think Scatterspike has a much better disguise. He is nearly fully burgundy in vehicle mode. The paint apps are pretty much identical except for a change of color. I do like that Hasbro went so far as to change the color of the band around the wheels.
Overall, Quillfire was a good figure. He is fun to transform, and he is a lot of fun to play with including good articulation, two weapons, and a moving mouth. So to get a second character based on the first was just fine with me. They can be a couple of grumpy Decepticons together forever.
