Marvel Comics #1000 is a celebration of 80 years of Marvel, featuring 80 different creative teams telling 80 one-page stories featuring various Marvel characters big and small… but one non-Marvel character managed to sneak in: Batman.
That’s right, the Dark Knight himself makes a cameo in Marvel’s big anniversary issue. It won’t surprise you to hear that he shows up in the story featuring Deadpool, the one character who can get away with such a thing.
In the strip by writer Gail Simone and artist David Baldeon, Deadpool decides to engage in some uplifting activities to celebrate Marvel’s 80th birthday, so he eats at a buffet dressed as Galactus, throws a luau with frenemy Cable, and goes on what he describes as a “peaceful boat ride” when in reality we see he’s stolen the Batboat from a caught-off-guard Batman. We only see the back of Batman’s cowled head as he yells after Wade Wilson making his watery getaway, but it’s unmistakably him.
