Alec Baldwin 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.
Alec Baldwin possesses at least two tentacles which he generally keeps hidden underneath his clothes, each of which split at the end to form a tridactyl hand. The tentacles are long - likely over ten feet - and thereby probably make up a majority of his torso space when folded inside of the body.
- Given that Alec Baldwin has been given the most air time of the "Hulu Aliens", it can be deduced that he is in fact the expedition's leader, if not the leader of their entire affiliation or species.
