Hey everyone here is my version of "bad guys' voices rated";  this is the current top five:

5.  E. S. Blofeld (James Bond) [Note that this position was a toss-up, because I also considered giving it to the character, "Skeletor" from the He-Man live-action feature, or the animated series either which/one], so Skeletor is in fact an honorable mention here.]

4.  Venger (Dungeons & Dragons)

3.  Darth Vader (Star Wars)

2.  Doctor Claw (Inspector Gadget)

1.  Borf (Space Ace)
