At the start of Batman R.I.P., Grant Morrison makes a reference to The Killing Joke, which is surprising considering the feud between Morrison and Alan Moore, as the opening sequence features the Dark Knight visiting the Joker at his cell in Arkham, while the Clown Prince of Crime plays a dead man's hand with his cards. As Batman questions him about what the Black Glove is, the Joker taunts him, saying how scary feeling about not knowing what’s coming. As Alfred says later in the story that Bruce Wayne has pursued physical and psychological perfection, shaping himself to the hero that Gotham needs, but is that enough to take down the Black Glove?
As Dr. Simon Hurt announces the Black Glove's next venture, which is the destruction of Batman, Bruce has to cope with the fact that his new romantic partner, Jezebel Jet, knows about his crime-fighting persona. While Jezebel tries to convince Batman that he is simply living a life he has fabricated in his own head as a child to cope with the death of his parents, Bruce is suddenly vulnerable, which is the perfect time for the Black Glove to strike as they drug Batman, beat Alfred, and wreak havoc upon the cave.
I have said this somewhere else that although Morrison didn’t coin the phrase “Bat-God”, they certainly have acknowledged it, whilst somewhat deconstructing it, specifically what happens to Batman when you take Bruce Wayne out of the equation. Morrison’s thesis on his entire Bat-run is to embrace every aspect of Batman’s comics history, including the stuff that most creators and readers would tend to ignore, such as the Silver Age comics where there was a lot of sci-fi going on as Batman interacted with aliens. How Morrison explains all of Batman's diverse history makes sense, is that Batman took part in an isolation experiment called Thogal which lasted in an effort to train himself to death and through this, he hallucinated all kinds of different Batman adventures.
As we see these flashbacks of Bruce taking part in the Thogal experiment, this is where Bruce develops the personality that will be a major part in the story, “The Batman of Zur-En-Arrh", and begins taking advice from Bat-Mite, who functions as the voice of reason. Right away, Morrison seems to be cutting loose and embrace the ridiculousness from Bat-Mite acknowledging that the 5th Dimension is imagination, to Batman has a conversation with two gargoyle statues. As trippy as the story goes, it can get even nasty, not least with the presence of the Joker as Tony S. Daniel giving several costume changes, whilst cutting open his tongue with a razor blade; certainly not for kids.
Although Nightwing and Tim Drake/Robin get their share of action as they battle the fun, eccentric members of the Black Glove, this is Batman’s story and how he has to think of EVERYTHING in order to win, as he states through the captions that are presented as passages from his Black Casebook. Going back to Tony S. Daniel, who proves to be one of the best artists for the grimness of Gotham, there is striking imagery throughout this book from a double page spread of the Batmobile, to two splash pages of Batman rising out of the grave.
Following the conclusion of Batman R.I.P., the remaining two issues are a change of pace as they tie in with Morrison’s crossover event that was happening around the same time: Final Crisis. Trapped in a machine that is used to create lumps that will become clones of the Dark Knight, Batman relives his history and even alternate directions where tragedy never struck and Batman was not conceived. Drawn by Lee Garbett, he’s having a blast illustrating fragments of the character’s history, in which Batman and his world have changed over the years, including how the Joker went from scary to ridiculous.
Despite its title, this is not the end of Batman, not even Grant Morrison’s time with the character, but arguably Batman R.I.P. – which does require multiple readings to get a full grasp of what’s going on – might be the finest work to come out of the writer's seven-year run.
