I'm getting the horrendously done ML Super-Adaptoid - Hasbro made it so he can't even strap on the damned shield! - so I gotta tweak that. But I also wanted to give him some classic wings like in his first appearance. Any suggestions on how this could be done?
So the early Super-Adaptoid wings are kind of an odd shape. Honestly, I would go look at some random plastic kitchen spoons at the dollar store etc., and cut them down and add any additional detail you want with fodder/sculpt. Once they are hit with the same base paint, and any dry brush/weathering that you apply to the rest of the figure, I don't think most people would know that the wings didn't come with it.
That is if you are going for a Tales of Suspense 84 cover type appearance. If you are going more for an X-men ('63) 29 cover appearance, you could probably just get away with cutting some styrene.
