There is a reason that Hellboy said what so many others before him have thought before: "That guy needs a vacation."
In the Batman/Hellboy/Starman limited series written by James Robinson and illustrated by Mike Mignola, Batman's latest pursuit of his nemesis ends with Starman Ted Knight's lecture being interrupted by a group of Neo-Nazis who attempt to kidnap him.
Faced with unknown enemies, Batman has to put aside his reputation as a grim loner and work with Hellboy, whose knowledge about the so-called Knights of October proves to be just as important as his skills and otherworldly appearance. ed by Ted's son Jack Knight, the current Starman, the group is ready to set off in pursuit of the Knights of October when Batman learns of Joker's return. Hellboy wishes him luck in stopping his nemesis, and Batman replies with a typically self-serious remark about the darkness waiting for him on his mission. Out of earshot, Hellboy utters one of the most obvious truths in comics, with Starman immediately agreeing.
The rest of the issue details Hellboy and Jack's mission to the Amazon, where they defeat the Knights, stop the resurrection of a Lovecraftian Old God, and save Jack's father. After the secret Nazi base is destroyed, the victorious heroes have to figure out how to get home. It's at that moment Hellboy is forced to eat his words, as a Batplane hovers above them, ready to pick them up on of Batman's ceaseless commitment to his mission. The Dark Knight was successful in his goal of apprehending the Joker, shifting instantly to helping his allies in their own mission.
Say what you will about his personality, methods, or how he may be Gotham's true villain, but when push comes to shove, you'll be glad to learn Batman doesn't take vacations.
