My friend just told me that, in acient egypt, there was a sickness the pharo would give to a bad slave called Pokitiru. Pokitiru would make that person feel powerful for a day, then die overnight. Doesn't that sound stupid?
First off, I have no clue if that's true. Second off, no pokemon virus. It would just give people more ideas that Pokemon are satanic.
But that does give me an idea. A pokemon that has abnormallyhigh stats in every stat, but dies in one turn. Oh, wait. Deoxys F pretty much has that covered -_-
