. . . I would be over joyed (I want Riolu to be in the anime and I would like to see how Dawn works with it in contest).
I would probly draw some coo fan art for them if it happened.
. . . But you know everyone else hear would whine about how "Dawns getting all the cool pokemon!!!".
Now many people were angry at the fact that Dawn caught buizel but now what if she caught a riolu how mad would you be?
