Originally, my thinking was that fusions are a bit different, because they're not really a crossover. They're AUs using the rules and structures of a pre-set fictional universe.
Technically, as an example, most people don't realize that Sentinel and Guide AUs are really a fusion AU (most people don't remember that The Sentinel was a TV show in the 90's). And a Pacific Rim Fusion would generally not have any Pacific Rim characters in it, and would adjust the Pacific Rim mythology as necessary for the fic to work. Same thing with Daemon AUs.
There's also been a new category added for Non-Powers AUs (such as coffee shop AUs, comic book store AUs, bagel shop AUs, prostitution AUs, etc.)
