Jacketinal
The word used to describe something that can use venom, poison, or other. This word can be used for any creature as long as it may contain things that are harmful to humans.

Examples of what may make something jacketinal: Shooting things like fire, ice, venom, acid, lava, or plasma from its mouth, being poisonous, and unable to be eaten, or having venom, fire, ice, acid, lava, or plasma in its fangs, claws, or other.
