How Come

Well, there are actually two answers to your question. You see, the first answer is that the makers of Pokemon Diamond, and Pokemon Pearl probably did not want you to be able to battle every single Opponent over and over again. If you could battle every opponent over and over again, then it would be a cheap and easy way to level up. The other answer, is just that you have not gotten far enough into the game. I remember some instances where I was looking for some people to battle again, and after I got farther into the game, I went back and I could battle them again.

So really, just continue to play the game and later on after you get say two more badges, then go try and fight some more people, some people simply need more time before they are ready to battle you.

Some people don't like battling the same people. After a while I look for new people i'll battle you if you tell me how

Well, first off, you may need to be farther in the game. Here is why:

When you go to refight them, their level is increased. The gamemasters may not have wanted you to fight a level 50 when you are 30. And since there is no program for fighting the level 20 again, they decided to make you wait.


The other possibility is that you just haven't tried enough times. It took two or three times to get this one person to rebattle me.

Just be patient.

Just get farther into the game and they will want to battle you.Because most of the time if you battle them again their Pokemon have gotten stronger.

It's because your screen has mutliple people in it. Go to a part of the screen
Where you can only see the person you want to battle, because if you see more than 1 they'll want to battle you too. Plus, you don't have to battle them, leave the area and come back and it resets.

They just randomly awnser yes or no to battle
