I believe this is yet another story about hunting humans that is inspired by the 1924 classic tale, “The Most Dangerous Game,” by Richard Connell. That story has been very popular and influential for almost a century. In this comic book version the tables are turned by an uninvited guest, who wishes to join the clique in their murderous ways.
