I binged. Check this site out and it will explain Maryann a little better :)
Maryann possesses an assortment of strange abilities which include: enhanced strength, superhuman speed, the power to influence or control the behavior of others, forcing shapeshifters into changing shape, immortality, blood that is black and toxic when consumed by vampires, being invulnerable to bullets, feed off of the energy of humans and the ability to transform her hands into claws that secrete a powerful neurotoxin able to neutralize the healing effects of vampire blood in humans.
