Pokémon Sun And Moon: Hau :-]

Hau is your rival/Pokémon loving friend. Do not be surprised if he asks to battle within the first minute of you getting your starter Pokémon. If you are in a town with Malasada,then you'll probably  find Hau there. I think that Hau will play a very important roll, and he will probably choose a starter that is super effective against yours. Hau will probably be a very interesting character.
The qualities in Hau should be that he's very adventurous, and that he's crazy. He should obviously love Pokémon, which he does. Gotta' Catch 'Em All:-}
