A Crossover Comic is a comic book that features characters from different comic book series or universes coming together in a single storyline. This genre allows for unique interactions and collaborations between popular characters, often leading to exciting plot developments. These comics can involve characters from the same publisher, like Marvel and DC, or even different publishers. Crossover events often attract fans from both franchises, creating a larger audience and generating buzz in the comic book community. They can also explore themes of teamwork, conflict, and the blending of different worlds.
