Other Universes – Events & Crossovers by A-Z

An ever-growing list of guides to indie comics crossovers. These are stories that hop from one comic book title to another to tell a complete story. I’ve labeled them as follows:

• Crossover: Stories with 2-11 direct crossover issues.
• Major Crossover: Storylines with 12-21 direct crossover issues.
• Major Event: Storylines with 22 or more direct crossover issues.
• Minor Crossover: Stories in which elements from one title impacts another, but may only cross over very loosely.
• Related Events: Stories impacted by related villains or themes that make more sense when read as a whole, but don’t actually cross over.
• Series Launch: A story designed specifically to launch or relaunch a series.
• Themed Event: A number of titles coming under one event banner that don’t actually cross into each other.
