Hiya! I merged your thread on over to an existing thread that also talks about Hau. :>
I prefer the rivals from the good old days. Red/Blue/Yellow, Gold/Silver. I remember always giving them really bad names... oh the good old days :')
Not to mention it's fun trashing the rival when they're a jerk :P.
I don't like Hau, really. For entertainment purposes, when there's a forced Double Battle Team-Up with Hau, I attack his Pokémon before attacking the intended Opponent. Hey, I'm a foreigner to Alola, I didn't know that's how Double Battles work. Isn't it more like a Battle Royal? *lie*
