Top 5 Famous Aliens

Famous celebrity aliens. They can be fictional or nonfictional (if you happen to know something...) My only rule is to eliminate human looking aliens. The lines would become to gray as to what is and isn't an alien; therefore, Superman, Mork, or the characters from 3rd Rock from The Sun have been ruled illegal. The famous alien has to look like an alien. Also, you will not find Alf or Howard the Duck on my list. They have no place near the top 5.

Honorable Mentions:
Spock, yeah he looks pretty human, so I kept him off the top 5, but technically he does have pointy ears.
Barf, or Barfollomew, from Spaceballs
Optimus Prime, believe it or not, he is an alien. He justs conveniently takes the shape of Ford Truck.
Alien, from the Alien series of movies
The Predator, crab-faced martian from the same-named movies.

5. Stitch, from Lilo and Stitch, not as famous as some, but he is an awesome little hawaiian bugger.

4. Chewbacca, "Would somebody please get this walking carpet out of my way?"

3. Marvin the Martian, Best Looney Tune character in my opinion. So he wants to destroy Earth. No hard feelings.

2. E.T, the Extra Terrestrial! How much more alien can you get. Plus he fixes ouchies, has a glowing heart, and can make bicycles fly. Every kid's fantasy friend.

1. Yoda, The ultimate little green man from outer space.
