The Visitor

Background
The Visitor is an alien of an unknown race that works for Eac. He is assumed to be a bounty hunter to some extent.

Although he seems terrible, he is usually friendly, but will attack viciously if provoked.

Genetics
The Visitor is a yellow-skinned "humanoid" that has to consume large amounts of proteins in a single span of twenty-four hours. The Visitor is not actually humanoid in its true form, but maintains the body-shape and details because it thinks that the best suits are made by humans. Visitor defies all laws of biology, it can consume incompatible proteins and change its metabolism speed.

Visitor is naturally mustard yellow in color, and can shape-shift. When it "digests" its prey, it uses a strange metabolism method. This causes bioplasmic energy to resonate throughout the area, this was an evolved trait that is speculated to be used when one of them is attacking and eating prey, this would allow them to electrocute the other hostile creatures in the area belonging to that species. The Visitor's only weakness known is Oxygen.
