Duncan

Duncan is the name of a dog who was owned by pirates that kidnapped Indiana Oakley back in the 1990s. Her sexual encounter with Duncan led to her giving birth to a dog-human hybrid named Zara Zimmerman months following her release from captivity, although Duncan had no contact due to being long gone with the pirates and moving on.

Backstory
Whilst Indiana Oakley was being held captive by pirates, she had sex with their pet dog named Duncan. Following her release, she gave birth to the first human-dog hybrid, but gave it away for adoption. The creature grew up to be Zara Zimmerman, and had little knowledge of her true parents and the circumstances. Duncan presumably went on to never know he had a daughter, and Zara would pass away 11 years following her birth.

Legacy
Zara's son and Duncan and Indiana's grandson Herbert Zimmerman visited Indiana when tracing his roots, and was informed about her sexual encounter with Duncan. Duncan appeared in a flashback when they first "met". When Herbert inquired if she knew what became of Duncan; Indiana replied that she wasn't too certain, although it was more than likely that Duncan would be dead due to the lifespan of dogs (it had been over 21 years since her encounter with him).
