Seth MacFarlane

Seth Woodbury MacFarlane is a liquivorous extraterrestrial of an unknown species which currently resides on the planet Earth, plotting with several other extraterrestrials to openly destroy humanity, ultimately planning to consume the brain matter of the entire Human race.

To go forward with this plan, he and the others (who all share enough common physiology to be considered belonging to the same species) have disguised themselves as Humans, created a company known as Hulu, and openly reveal their evil plans of world decimation to the public through commercials, even revealing their actual identities. This is done because they feel superior to the Human race, and have correctly deduced that despite their openly revealing their ultimate plans, no one will do anything to stop them, and so they let their arrogance run wild.

Seth MacFarlane has a secondary (or perhaps primary) head in what normally appears as his navel. Despite being liquivorous, it possesses razor-sharp teeth. It is equally capable of speaking as the upper, perhaps false head is.
