Picking up from "Volume 9: The Wild Hunt" (Vols 10 and 11 were collections of Hellboy short stories), Hellboy faces his destiny as the potential destroyer or saviour of the world.
While this is a potentially exciting finale, the book feels oddly flat. Hellboy doesn't have many lines and his wit and charm is mostly missing (until his final scene). I think part of the problem was that this didn't feel like the end you would expect. I expected a summation, a kind of retrospective taking in his friends and family, the adventures he's been on, a look back on the long, long journey he's been on to get him to this, his final hour. Instead, there's a brief introduction and then Hellboy's plunged into endless fighting against monsters for the rest of the book.
And yet how else could it have ended? Nearly every book in the series has seen Hellboy punching out the monster at the end, why break the formula now? Well, sure, but it still felt rote and somewhat impersonal to see Hellboy fighting the monster at the end and then... what happens, happens.
But this is the comics world, it's all origins and middle stories. While it purports to have endings in the form of deaths of famous and favourite characters, those characters always come back - always. While this book ends the main Hellboy series, I wouldn't expect that this is the end of the character, not by a long shot.
So fans of the series get an ending but as with most endings, its unsatisfactory and doesn't live up to readers' expectations. But it's an ending. And as said by one of the characters in the book about Rag Narok "it is the end. But it is also a new beginning". Methinks the red guy ain't down for the count.
