The Ford Mustang is iconic, but may soon become mythological.

Ford launched a social media promotion in June asking people to submit potential names for a new Black Accent appearance package that will be soon offered on the Mustang.

The pony car is currently available with a simply named Black Accent Package that features black Mustang badges and black aluminum wheels, plus a black grille, roof, spoiler and mirror caps.

A Ford spokesman told Fox News Digital that the new package will be different, but did not provide full details.

The automaker received 25,000 entries before it stopped accepting suggestions and has since narrowed it down to four and wants to hear from fans again on social media before it makes a final decision.

The finalists include the self-explanatory Nite Pony, Shadow Stallion and Shadow Mare, plus one with a connection that requires some knowledge of classic history: Alastor.

The name has had several uses over the millennia, including for avenging demons and spirits, but one is most relevant to the Mustang.

The company recently filed a trademark for the name Dark Horse, which was either a red herring or may be used for something different, but has not yet done the same for any of the four finalists.

Whatever it ends up being called, the new black Mustang will soon be overshadowed by the new next-generation 2024 Mustang that's set to debut at the Detroit Auto Show in September.
