Scary Becky is tough and mean. Scary Becky will kill your family cause she has already killed hers. She usually has 2 sisters. Probably named after states or places on the Earth. Probably born a normal child than after an incident never the same again. Don't be in the same car as in Scary Becky and don't mess with Scary Becky.
