Vector Mark's hybrid form, when he's transformed only halfway towards a pony. He still retains his emotion sensing antennas, his six-legged Changeling body frame and the large abdomen where he stores his emotional energy, but everything is covered in fur and for the rest he looks like a pegasus pony. He eventually uses this form when he's with his daughter Caterpillar, matching her shape to make her feel less like a freak.

Drawn in InkScape.
