Cupida Hartnell

According to a Retconning Crocodile, the Creator of the Crew of the Copper-Colored Cupids was a genius, unlike the Cupids themselves who were "inconsequential fools". The Crocodile further described them in Auteur's terms as "if the lovechild of Urizen and Nikola Tesla had pursued a double career in robotics and biodata-manipulation".

Behind the Scenes
Cupida Hartnell is likely named in reference to William Hartnell, the "creator" of the character of the Doctor.
