The Real Ghostbusters Frightful Four

 When people think of the Frightful Four, they tend to think of the supervillain group who would oppose the Fantastic Four in Marvel comics. Howeverthere is another Frightful Four from Marvel. Marvel UK's The Real Ghostbusters issue 118 introduced readers to a group of ghosts based on the classic universal monsters but wearing uniforms similar to the Ghostbusters. 

This quartet were sent to capture and punish the Ghostbusters for their crimes against the spirit world. Basically, Ghostbuster Busters. 

The team consisted of Frank (the Frankenstein monster), Arnold the Werewolf, Wilbur the Mummy and Vigor the Vampire the leader of the group.  Vampire the leader of the group. 

Their first appearance was in a text only story but in their second outing in issue 136 they would get a full comic strip story.

The Kenner Real Ghostbusters toy line included a Monster Series of toys based on Universal Monsters, including Dracula, Frankensteins Monster, a Werewolf and Mummy. The closest we got to toys of the Frightful Four.
