Mark XVII
From Jenny Everywhere Wiki
Mark XVIIs were a mark of Clockwork Cherubs from the Crew of the Copper-Colored Cupids. Cupid Fact File #001 compared them to the Mark Is, noting they were the youngest Mark of Cherubs yet extant as of the last update to the File. Mark XVIIs were small and streamlined, with round heads, plus-sign-shaped eyes, and bendable limbs. They had a power core in the centre of their chest, from which piping ran on the outside, forming an X pattern. (PROSE: The Crew of the Copper-Colored Cupids)
