So . . . this was supposed to be an ATC (Artist Trading Card), but things didn't quite work out that way. The idea was that all of the parts to make Rainbow Dash would have been mounted on an ATC-sized "sprue tree", much like the parts for a model car, plane, etc. While they weren't my inspiration, Hasbro does have similar "My Little Pony: Pop" toys in the stores right now, although those kits make 3D ponies, not 2.5D ones like mine. ("2.5D" is the term I use to describe figures made mostly out of 2-dimensional planes arranged in a 3-dimensional manner.)
My Rainbow Dash figure does fit within an ATC's 2.5" x 3.5" dimensions when she's disassembled, but the angled wings don't lie flat enough for the look I wanted to achieve (I'd have to make the wing assembly a 3-piece affair for that). Originally, rather than the peg-and-hole interfaces you see on the final version, I had intended to make all of the parts connect to one another via slots, which would have resulted in everything lying flat like I wanted (and more pieces), but my plans changed while I was working on the vibrantly-hued pegasus. I still like the idea of an ATC that's also a snap-together model kit, so maybe I'll make another attempt in the future with different subject matter.
Cardboard from a potato chip box, newsprint, tissue paper, white glue, acrylic paint, marker, ink, and colored pencils.
2.5 cm (1.0") wide x 6.4 cm (2.5") long x 6.2 cm (2.4") tall.
Four points; all of her limbs can rotate at their connections.
Of course, as she was designed for one, specific pose, the practical usage is relatively limited (i.e., she'll fall over if you move her back legs out of alignment).

It might seem counter-intuitive, but I think it would have actually been faster and less labor to sculpt her in full 3D (I had to do a fair amount of design/prep work for this project before I could start physically fabricating anything). I imagine that her rainbow locks would probably have been just as time-consuming to paint regardless though.
