whats a......

Pokerus is not a thing. So, you would not say whats a Pokerus. Instead, you would ask what is Pokerus? To answer your question, Pokerus is a rare virus that your Pokemon can become infected with. The chances of one of your Pokemon ever getting infected with the Pokerus virus are slim to none, but you can always hope that they do. You would want one of your Pokemon to become infected with the Pokerus virus because Pokerus is not bad for your Pokemon. On the contrary, it is actually really good for them. While infected with Pokerus, your Pokemon's Iv's increase by two times after each battle. This means that when he grows a level, his stats will increase by twice the amount. Pokerus randomly infects a Pokemon. Look up a video tutorial for help with the Action Replay.


Hope this helps.

It isn't an item. It is a Pokemon disease. You probably won't get it without an Action Raplay, but with the chance you will get it, spread it around. It is contagious, so infect your Pokemon with them. It goes away after a couple days, so spread it as best you can.

With this disease, your Pokemon grow twice as fast as normal. Say a Pokemon gains a level and gets +2 HP. With this disease, it gets +4 HP!

Pokerus is a virus that can be caught legitly by battling an infected Pokemon in the wild (extremely rare)

Or by using AR

Pokerus is a good thing for ev training it serves as a macho brace, it doubles the ev's earned by battling pokemon

So pokerus + Macho brace = Major EV training
