The Crew of the Copper-Colored Cupids (series)

The Crew of the Copper-Colored Cupids is an independent science-fantasy series (comprising short stories, text adventure games, cartoons and webcasts) created by Lupan Evezan and Aristide Twain. It focused on the titular organisation, a group of dimension-travelling androids.

Crossovers with the DWU
In September 2020, the Retconning Crocodiles, a villain from the series, were mentioned in A Worthy Successor as an easter egg.

A more substantial crossover between the series and the DWU was released in December in the form of Auteur's Abecedarium. Written by the Faction Paradox writer Jacob Black, this short story featured Godparent Auteur of Faction Paradox, who tried to destroy the Cupids' universe by sending them a seemingly-cursed book.

Additionally, versions of the events of The Big Bang and Time Lord Victorious were mentioned, and spoofed, in passing in the earlier solo Cupids story The Grand Multiverse Hotel: it was mentioned that in one universe visited by the main characters, they'd witnessed a time traveller with a bowtie who had blown up his reality, put it back together again, and later nearly blown it up again by trying to kill Death. However, this was only a minor cultural reference to the DWU, rather than another straight-up crossover.

Behind-the-scenes connections
In addition to Faction Paradox writer Jacob Black having written the actual crossover Auteur's Abecedarium, one of the series' two primary creators was Aristide Twain, who also received a credit for the "concept" of the 2020 licensed DWU webcast, Shadows of Doubt.
