you can either use theft an reds pikachu or try catching a pikachu that has it. reds pikachu is a sure thing though.
You can't get everybody's phone number.If this is to battle him again,you have to beat the elite four again.
all you have to do is beat cyrus and beat red so he will call you to have a battle against ash.
