Kat's girlfriend (AKA Doctor K) looks like Kat but with a more feminine appearance. As she is the same species, she may have the similar abilities as Kat.
She is seen only once in the first season at the conclusion of "The Kitty Vanishes" as a hologram Kat is looking at.
She is seen more often in Season 2, in the episodes:
- "Birthday Bashed" where Kat converses with her hologram.
- "Who's Haunting Who?" where Kat looks at her photo.
- Plays a major role in "The Kat Went Back Part 1" and "The Kat Went Back Part 2", and she's the first Kat Nebulan shown speaking a human language.
