Batman Comic Generator
The Batman & Robin Comic Generator is just the kind of single-serving site we like: retro, referential, and a step up from image macros in its usefulness for helping non-‘Shoppers create new things on the quick.
Just what are Batman and the Boy Wonder saying to one another as Batman slaps his cheeky sidekick in the face, complete with motion lines? Editable captions are limited to 80 characters apiece.
