Hello....

 If you could create a monster would be one that did not have head and deformed.

My monster called the embittered.

Scare people because it has no head and is deformed. My monster lives in the street of New York. My monster misbehaves, scream, change shape. My monster was not happy, and comes from a legend that somebody removing the head killed him. this man was as a monster to take revenge on the people, and scares people as part of their revenge. and more hates all those who are happy. When the people is happy that monster come and damage all relationship.
