In ORAS, there is a man near the battle resort who says something in Japanese. I however, am American, and haven't the slightest clue what he's saying. There is also some of the Japanese text that is in blue, so I think something is special in what he is saying....
>"I can tell by the look of you you're no ordinary trainer. I'd recommend training up some more, and challenging the Pokemon World Championship."
^^ Translation, I did not translate myself.
This is the real-life Pokemon World Championship, not the PWT. The blue part was 'Pokemon World Championship', it's nothing you should worry about in-game.
Hope I helped. :) Source
