Ranking all sorts of undead from the most basic to the most specific iteration.

I wanted to know what the best undead was, because they are such a vast category of monster, and they are so intriguing to me, horrifying for both their distance, and close proximity to reality.

By using the S.D.T.N. method. Standing for Spook, Danger, Transformation and Name, I will rank each undead's ability to scare, dangerous powers, their transformation from their natural form, and the sound, creativity, and public understanding of their name. Each will provide statistics into how good this undead is, save for the transformation, which exists mostly to classify each undead into a reasonable weight class to compare them to.
