Source: Nutcracker in 3D
Location: Rat City
Threat Assessment: 5. Well.. he has his own army of nazi rats, his mother knows black magic, and he's a huge rate that can make his teeth grow five times their size with annoyed. For a kid's villain he's not only creepy but darn right scary.
Limitation: Not so smart, a little girl beats him.
Personal note: What the hell were these people smoking?
