Anima/Thriller is the Mother to Vance and Nehdri, whom are fraternal twins. She is able to take on a human form, which you see here. She goes by Anima or Ani in human form and by Thriller in her natural form. Her natural form was inspired by the song by Michael Jackson, believe it or not. She has changed over the decades, but I rather like how she looks now. If you can't tell she's made up of five species: canine, equine, avian, lizard, and human. There's a story behind it, but why bore you with that eh?
