Shan Yu's towering height, sickly gray skin, purring voice and cold, eagle-like eyes make him terrifying enough. However, even more scary, is the destruction of villages, soldiers and civilians he leaves in his wake in his goal to conquer China.
Much like Shan Yu, Sykes's towering frame and husky voice make him absolutely terrifying, not helped by the fact he has two scary Dobermans. Add to the fact he terrorizes Fagin-a homeless man-for money and has no problems hurting children or animals, and you have yourself a completely monstrous villain.
