I've seen this site before, but having been reminded of its existence by this thread, I now remember how amazing it is.
Not going to post any pictures this time around, but I will note that due to the system that's used to combine the names of each Pokemon, it's not that hard to create a fusion that inherits traits of multiple Pokemon but takes its name from only one. (or at least, that's how it appears)
Not that interesting, but I found it noteworthy.
EDIT: Anything in the first slot with Ditto in the second slot, or the reverse. This is what happens when Ditto fails to transform completely.
