HEy what about WALLY!!!!

Hey is Victory Road the last place Im ever going to see and
battle WALLy because he is quite a challenge and ... I miss him.
And one more thing What is POKE RUS and where can it be boght/found...

You can re-battle him in Victory Road just like you can any other trainer. The pokerus is a very rare virus that does nothing bad at all. In fact, it makes your pokemons EV gains doubled! After every battle, there is a chance that your pokemon will be infected. This is about three time as rare as getting a shiny. If you have a pokemon with the pokerus, do some battles and it wil eventually spread to your other pokemon. The virus eventually goes away, and there will be a teeny black dot in their summary that says that they already had it and are now immune to it, and that it cannot spread to your other pokemon now (but they can still get it in the normal way). Their EV gains will also stil be doubled. The only way that does not invole luck is with a code.
