beserkers are reptillian creatures about 2 metres tall that hunt their prey using their heat vision,allowing them to see just as we do,but see heat aswell,kind of like a snake.it can also sense heart beats,making it incredibly dangerous.this was made when i imagined what a half alien(the one from avp)a future predator(from a show called primeval)and a velociraptor would look like,so the beserker was born.
