Virulent

Don't you know that I am TOXIC

Their antlers and fangs are in fact venomous/toxic. Like a 'poison point'type of way.
Toutch them and you will be very, very ill. Their venom will not kill a regular person, but WILL be pretty dangerous to anyone in a bad health.
They're cold and bitter. accompanied with a serious inflameable temper, it it not the person you want on your bad side.
as they WILL MAKE SURE bad things come your way.

Bodywise they're more a hare type of deal. Though edges and huge lanky paws. with some extra fluff around the face.
