Bandersnatch (Pesvastus dissimulatus) is a form of sasquatch that has been infected with the Human-Metahuman Vampiric Virus (HMHVV) but without manifestation of the vampiric aspects of the virus. It's coat is more mangy-looking than a normal sasquatch and it's strong arms are more elongated as well. It has the teeth of a carnivore, and it does prefer fresh meat, either still alive or recently killed.
The supreme advantage the bandersnatch has against its prey is the ability to refract light around its body, making it virtually invisble to the naked eye. Since it refracts lightwaves, ultraviolet and infrared wavelengths are affected as well. Combined with the sasquatch's mimicry ability, and the bandersnatch becomes a powerful hunter indeed.
