The top version with no wings is Pastel's "Simplicit" form. Him in his glory, but not over-fantasized. The one below that is his "Ascended" form, him in his glory to a power of 2.

The pictures to the right show what would happen if you were to slice this lil babe in half. No bones, no guts. Just hollowness, and of course pink sparkly goop. This also doesn't at all harm Pastel in any real sense, as his body will just regenerate when he becomes frustrated with being 'injured'.

There is more to this on the way, but ehhh I'll just put it in the Explicit version. :/
