Chucky - Brad Dourif
Even though Chucky himself is just an animatronic doll, he is still voiced by a human. Brad Dourif lent his voice to the horrifying serial killer-infused doll that wreaks havoc on an unsuspecting family. Child's Play has tons of sequels and new adaptions, but the original is still the best.
Azazel - Jason Flemyng
The X-Men franchise has tons of bad guys and villains, but Azazel stands out for his shocking red skin and over-powered ability of teleportation. His first appearance is in X-Men: FIrst Class. Jason Flemyng had to sit in the makeup chair for hours so his skin could be painted red.
