Her Undercover Panther is a paranormal "shapeshifter" romance set mostly on a pair of South American islands. One island is a hedonistic resort where, for a large fee, shifter men are made romantically available to wealthy non-shifter women for a few days. The other island contains a top-secret biotech laboratory, and a village of native shifters. The FBI suspects that the laboratory and its Dr. Moreau-like owner are up to no good, so Special Agent Tara Strong is sent to investigate. She's undercover, though, which means she'll have to pretend to be one of the rich patrons of the resort, which of course involves pretending to enjoy the affections of Luis, the shifter man she's chosen to rent for the week. Luis is actually an FBI informant, though, so he accompanies Tara as she tries to find a link between the laboratory and the shifter village.
For Tara Strong's voice, I couldn't think of a better model than the voice actress of the same name. Specifically, her performance of Batgirl from Batman: The Killing Joke.
Luis has a generic Spanish accent, but otherwise has no real vocal model.
Andrew is a by-the-book FBI chief; I imaged him as Dan Aykroyd from Dragnet from the '80s.
The rest of the characters are relatively minor, and use voice models that I'd already developed for previous projects.
Her Undercover Panther is a good representative of the paranormal shapeshifter romance genre. It follows the conventions of the established lore without too much exposition, and the descriptions of the scenery are immersive.
