This Particular Lunatic (Book Three, Part 10: The Dragon, Batman: Gothic)

Previously in The Last War in Albion: Grant Morrison’s first major hit was Arkham Asylum, a Batman graphic novel whose dense symbolism included, among other things, the Tower card and the Great Dragon.
This particular lunatic claimed he was the Biblical Anti-Christ and promised to return to Gotham one day, on the eve of the battle of Armageddon. -Grant Morrison, Batman
This suits Crowley’s larger signification, but is tangental in the extreme, relying on Dīs Pater’s later conflation with the more traditionally bestial Orcus, who provided the roots for the French ogre and Italian orco, from which Tolkien’s orcs and the ensuing high fantasy trope emerged. More abstractly, however, the presence of a fire-breathing mouth implies a dragon, and Morrison’s association of the figure with primal chaos cements this tidily, suggesting again a flaw at the heart of things.
Morrison states that the dragon is opposed by reason, represented by the spear. Within the lore of DC Comics, then, this would imply Batman, the world’s greatest detective. Unsurprisingly, however, things are not that simple given Morrison’s conception of Batman. In the gallery at the end of the book that serves as a cast of characters, Batman is given a brief, anxious narration: “Criminals. Criminals are a terror. Hearts of the night. I must disguise my. Terror. Criminals are Cowardly. Superstitious terrible omen. A cowardly lot. My disguise must strike terror. I must be black. Terrible. Criminals are. Criminals are a superstitious cowardly lot. I must be a creature. I must be a creature of the night. Mommy’s dead. Daddy’s dead. Brucie’s dead. I shall become a bat”. This invocation of “creature” makes it clear that Batman is not some dispassionate force of reason who can combat the Great Dragon within the Tower, but rather a force of the Dragon. The clear implication—which Morrison pays off—is that Batman is only ever confronting himself as he battles his way through the Asylum.
It is worth stressing that this is not all a bunch of mystic interpretation being imposed onto the text. Arkham Asylum makes active and extremely literal use of these symbols in accordance with their occult implications. The aforementioned passage in which Amadeus Arkham’s journals transition from talking about the Dark Tower to the Dragon plays out as narration overlaid with Batman encountering Killer Croc, a relatively recent addition to Batman’s rogue’s gallery created by Gerry Conway in 1983, with “And face the Dragon within” appearing in a half-page panel of Killer Croc. The Dragon easily gets the better of Batman, hurling him out a window. McKean draws this with clear resemblances to the Pamela Coleman Smith rendition of the card—a tall panel in which Batman crashes out of an upper spire of the Asylum, lightning crashing behind him. Batman falls, then catches himself, pulling himself up to find a statue of Saint Michael defeating Satan.
This, of course, is the event described in Revelation when the “great red dragon, having seven heads and ten horns, and seven crowns upon his head,” provoking a “war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, And prevailed not; neither was their place found any more in heaven.…
