Actually, Batman is merely Edward Cullen’s final form

Robert Pattinson is now Batman, which means for three hours he broods around the dimly lit city of Gotham clad in all black, while solving crimes and shirking his responsibilities as head of Wayne Enterprises. The actor does a bangup job of bringing a new Caped Crusader into the cinematic world, enough that it’s easy to forget that his casting was once thought controversial.

Some fans griped that the dreamboat star of the vampire romance saga Twilight could never embody the gruff caped crusader. Others countered that Pattison had taken on some very eclectic roles since his Twilight days, and that proved his acting chops. Both of these factions are missing the point: Bruce Wayne is already the perfect evolution from Edward Cullen. No one could be more suited to take on the role than Robert Pattinson.

If you paid attention in high school literature class, you may remember the Byronic hero, but for those of you who have filtered out that information, it’s a core character archetype of Gothic Literature. The broody, tortured, sullen, but honorable, man who wanders the moors (or similar) with a heart full of secrets and/or vengeance. Sure, sometimes he has a softer side buried deep deep down, but on the outside it’s all brooding in the halls of Forks Community High School — or on the edge of tall buildings.

Yes, Batman is a Byronic hero and, as someone who spent four years of his early career channeling that energy, Robert Pattinson is uniquely suited to take on the role. For instance, when playing Edward Cullen, Pattinson specifically chose not to portray the vampire the way that author Stephenie Meyer penned, as the super beautiful guy who is amazing at everything.

“I think a lot of actors tried to play that aspect,”
