As a B.P.R.D. and Hellboy fan who's read all the collected volumes up until this point, I couldn't have been more happy with the epic conclusion to the Plague of Frogs story arc. All the major players are brought together in this volume. From the heroes, you have Abe, Liz, Yohan, Kate, and even Hellboy. From the villains, you have the leader of the underground Hyperboreans, the Black Flame, and Memnan Saa. The combination of all these great characters butting heads makes for an exciting read.
Fans of Abe and Liz will be particularly pleased, as those characters each experience major revelations and turning points. I'll try to explain without giving too much away. We've been given Abe's past before, but in this volume we get a preview of Abe's destiny. The news is quite shocking for Abe. John Arcudi's writing and Guy Davis's artwork skillfully convey Abe's range of emotions, from utter disbelief to fatalistic acceptance. Along with a a preview of Abe's future that Liz sees, the character arc of Abe Sapien makes a hard right turn in an interesting direction. As a reader, I now have an appropriate amount of tension about what fate holds for Mr. Sapien.
Liz Sherman's character is also given further development. Liz gets her longest and harshest preview of the future yet. In previous volumes Liz's previews of the future always seemed like vague dreams. Sure, they were scary, but they didn't feel real to the reader. This flash forwards feels much more concrete. It even has a scene that foreshadows developments for the other B.P.R.D. characters. Plus, it ties B.P.R.D.'s apocalyptic visions to the apocalyptic visions from Hellboy. I really got the sense that Arcudi and Mike Mignola know were they're taking this story, and as a fan I'm apprehensive about if my beloved B.P.R.D. characters will be able to avoid their doom. Also very important to the story in the choice that Liz ends up making. It is her own choice this time, not a result of being manipulated or an unconscious reflex, which makes it so much more important. Liz's choice not only has personal consequences for Liz, but also has immediate consequences for the entire world.
If you're a fan of other characters, don't worry, as most characters end up getting enough focus for you to be satisfied. Fan-favorite character Lobster Johnson finds an appropriate conclusion to his story, Kate's relationship with her friend from Germany gets further developed, and hell, even Agent Devon gets some time to differentiate himself from the other faceless B.P.R.D. soldiers. The only character that doesn't get much focus is Panya, but that seems intentional. Panya is lonely and most of the other characters have forgotten about her. It seems like Arcudi is trying to make the readers realize that even THEY have forgotten her. Also, I can't believe that some scenes near the end of the book actually made me feel sympathetic towards Director Manning. All-in-all, most characters had interesting moments.
I'd be remiss if I didn't mention the excellent artwork in this volume. Davis (with a little help from Mignola) hits it out of the park with his creature designs. As a fan of grotesque creatures, I was really satisfied with all the new ones presented. Let's just say we get to REALLY find out what those bug-robots the underground Hyberboreans use are for...
Now let's talk about the extras. For extras, this volume contains an afterward by Mignola and character design sketches from Davis and Mignola. This is probably the most interesting set of sketches I've seen in one of these volumes. There were a large number of new creatures that had to be designed for this volume, so the sketches go in depth on that design process. You can see how Mignola and Davis pass ideas back-and-forth between each other. Many of the creatures have several pages of sketches until their final designs are arrived upon. This design process is interesting to witness.
Finally, I need to address a particular criticism in the other reviews. Some of the other reviews have complained that this volume isn't conclusive enough for being the last part of the Plague of Frogs story line. They mention how there are still unresolved story threads, and that new threads get started in this. Well, both of those things are totally understandable if you realize what the Plague of Frogs story line really is: the first act in a 3 act story. After the first act of a movie or play, are all the story lines resolved? Of course not. By that point the audience is given a clear understanding of what the story is, where it will go, and some reason to care about what's going to happen. That's exactly what happens in this volume. The frogs were only minor players in the greater B.P.R.D. story, and now that I see where that story could go I am super-excited for the future of the B.P.R.D. series. Also, I'm not just making up the idea that Plague of Frogs is act 1 of 3 in the B.P.R.D. story - Mignola himself says that in the afterward for this volume.
I can't recommend King Of Fear enough. I finished reading it yesterday and I'm still thinking about everything that occurred and all the things that could happen in the next major act in the great B.P.R.D story, Hell on Earth. If I'm still thinking about a book or movie long after it's finished, that's a sign to me that it was good. Hopefully you will enjoy King Of Fear too.
