Nextwave is a humorous comic book series by Warren Ellis and Stuart Immonen, published by Marvel Comics between 2006 and 2007. Nextwave consistently features extreme violence and comedy, and simultaneously satirizes and celebrates Marvel's superhero comics. The series frequently uses flashback scenes in which existing Marvel characters such as Captain America, Ulysses Bloodstone and the Celestials act grossly out of character for comedic purposes. In an interview, Ellis said: "I took The Authority and I stripped out all the plots, logic, character and sanity. It's an absolute distillation of the superhero genre. No plot lines, characters, emotions, nothing whatsoever. It's people posing in the street for no good reason. It is people getting kicked, and then exploding. It is a pure comic book, and I will fight anyone who says otherwise. And afterwards, they will explode".
