You got Pokerus in gen II!? Back then the odds of getting the pokerus was far lower than it is now. A 3 in 65,536 chance of finding it, plus you had no idea that a Pokemon would have it. There is a 1 in 8,192 chance of getting a shiny Pokemon. You can see why this is a very lucky thing for you.
Go to 5th Gen Pokerus Trading thread please.can someone please trade a pokemon with pokerus to me on my pokemon black??
