Pentagon

He's a chupacabra. When he was a child,he lived with his big family/tribe,and he was the son of the leader. But once humans found the tribe,and killed everyone who didn't hide. Then they found small chupacabras who hidden in the grass or in their holes,and took them to the laboratory. Pent was only one who survived after the experiments in the lab,and he grew up. Once at night,he saw three chupacabras in his age through the small window in his "dungeon".He escaped,and followed them,but they didn't recognise him,and fought. When he was wounded and weak after the fight, Vempels found him. He decided to stay with them,as a pet. He still dreams that he may find his family again.
