So I read in a magazine a boy named Ash Ketchum and his greninja were able to sort of fuse and create an Ash- Greninja. Is this fusion possible with all types of Pokémon? Or was that story a hoax?

It’s difficult to say, anonymous. The “Ash-greninja” is a fairly new discovery, and not much is known about how it works and whether or not it’s possible for others. We assume that it’s similar to mega-evolution, but until we fully understand that, it may still be a mystery.

I do know, though, that Ash Ketchum is a rather unique individual, so it wouldn’t surprise me in the least if this is a talent of his alone. On that note, I fully believe that the story was not a hoax … but then again, I first learned of this evolutionary anomaly from Professor Oak, so perhaps my opinions were influenced just a little from the outset.
