Origin

Pentagon Jr had long felt he had not received enough respect and gratitude from Mexican fans. Pentagon, obsessed with injuring and hurting is opponents, would begin to gain a reputation for being overly sadistic and violent. Even more so when he would begin dedicating his unique brand of violence and wrestling to an unseen master. Eventually this would turn out to be Vampiro, despite his alter Ian Richard Hodgkinson being a color commentator for Lucha Underground. After beginning a new technique, Pentagon would go on to break the arms of several Lucha Underground competitors, such as Argenis and Super Fly.
In a daring and bold move, Pentagon Jr would even attack and break the arm of then champion Mil Muerte.
