The rivalry between vampires and werewolves is overplayed. Lets get some new paranormal rivalries going on.
Um.
Harpies vs Selkies, sky vs sea?
Vampires vs the ghosts of blood donors?
Aliens vs Mole Men, extraterrestrial vs intraterrestrial?
This is hard.
Aliens vs Fair Folk. “IT’S TIME FOR THE ANNUAL HALLOWEEN ABDUCT-OFF! LET’S GET CARRIED AWAY, SHALL WE?”
Ghosts vs demons, always fighting over who gets to possess the mortals
Centaurs vs werewolves – constant territory disputes and arguing about whether the Man controls the Beast or vice versa
Dragons vs wyverns, where wyverns are like the second-class citizens of the dragon world because they don’t have enough legs and all the dragons laugh at them
Mermaids vs kelpies. STOP DROWNING PEOPLE IN MY HARBOR, THIS IS MY SODDING HARBOR
