There is one legendary pokemon that sets even the most powerful pokemon quaking in their boots. Some say that it is uncapturable... others say that it is exactly the opposite - that even if you don't want it, you may have
thousands in your collection, and never even know it. Maybe even more.
It is a poison-type pokemon, vile and corrupt, that delights in causing torment to everyone - pokemon and human alike.
I bring you.... Germo:

What? Don't see him? That's exactly his plan. He is tiny. So tiny that he could be piggybacking on any pokemon and you would never notice, except for a strange bugged pixel. For that's the size of germo. And with the visual capabilities of the strange lands that the pokemon live, that makes him virtually undetectable. Let's look a little closer:

Not that scary you say? Well, perhaps not at first glance. We have available here at the pokecenter a device that lets us look closer than close. To bring this fuzzy pixel to full resolution!

And there you have it - the dastardly Germo. He settles into pokemon, slowly working his poison into them until they are finally defeated, where he tries to jump to a new host.
SO... next time you think you spy a strange pixel on your pokemon... don't just assume that it is a strange art style... or a bug in your player... it could be germo....
DUN DUN DUUUUUN!
!!! A worthy opponent!
