One from my massive vault of rp characters that I use, this is Jaicen a rabbit who upon his death was brought back to life by his younger brother, a white alligator named Incognito. (Jaicen takes after his father) though you can't see, Jaicen has alligator fangs. Anyways, his brother was a scientist and had brought him back to life, but not without consequences. Jaicen is able to take a ghost form.
