1) Other then the determination he has, Skulker is also an example of brawn and brains. Brawn being his fighting skills and brain being the knowledge he not only possess in terms of hunting, but in general other areas such as leadership skills. I always love it whenever he's with bunches of other ghosts because he usually acts as the "leader". It's a nice quality of his'. I also LOVE his face, cutest shit ever.

2) I don't really have a dislike.

3) Skulker/Sam! SKULKER/SAM!

4) His ghost powers are fine.

5) Read Question 3.

6) His original actor. MUCH sexier. I have no problems with his latter, but his first is talking sex.
