September 2017 is SYFY's 25th anniversary, so we're using it as an excuse to look back and celebrate the last 25 years of ALL science fiction, fantasy, and horror, a time that has seen the genres we love conquer the world of pop culture. For us, that means lists! ALL THE LISTS! We'll be doing two "25 greatest" lists per day all throughout September, looking back at the moments, people, and characters that shaped the last quarter century. So keep checking back. Please note: Our lists are not ranked; all items have equal standing in our brains.
What items in our lists were your favorites? Did we miss something? We welcome respectful debate and discussion, so please let us know in the comments!
The comic book crossover is a time-honored tradition that sees characters who don't interact month to month suddenly thrust into an adventure together. Sometimes it's across different parts of the same world or comic book universe; sometimes it's across different parts of the multiverse; and sometimes it's even across multiple comic book publishers!
Over the last 25 years, the comic book crossover has often been a summer event and only rarely been between multiple companies, but it's churned out some of the most fun and craziest stories we've ever seen. In alphabetical order, here are 25 of our favorite comic book crossovers since 1992.
