Concept art for the Pony Emblem project.

Dusky is something of an oddball among the cast here. Speedster is actually the Myrmidon equivalent, so yes, Dusky is a pegasus ground fighter. The scarf and hairstyle are the same as her usual design. The headband and sash are Speedster standard issue gear and are there to give that sort of agile fighter feel. The vest is a leather armour that constricts her wings and is the in game reason for her staying grounded. The foreleg shoes are basically metal toed and heeled slippers (Speedsters use horseshoes, the sword equivalent).
