[Timber Wolf]

ah come on where's Alien? it may not be big, but if you can blast it out the airlock with a grappling hook and it crawls back up it to get you screams hardcore
So here's my list

5.Stay Puff....
He's funny and awesome, you can't deny it

4.Nosferatu
One of the original vampire movies, and I think he's creepier than Dracula

3.Frankenstein's Monster
And I mean the real one, not the dumb one in the various movies, I know they made one version on the 90's that was a lot closer to the book, but the acting was atrocious

2.Alien
I've already explained, Alien was the best, and Aliens(Alien 2) was awesome, the rest of the series isn't worth mentioning

1.Agrajag
He's been killed more times than Jason, and still keeps just appearing to be killed.....again, but when he's re-incarnated in his Cathedral of Hate, the description of him is awesome, and ironic to no end
