[Kajitsu]

Regirock, Regice, Registeel, Zapdos, Moltres, Articuno, Kyogre, Goudon (or whatever it is; I don't have Ruby), Rezi-something (you know, the dragon), Raiku, Entei, Suicune, Really Cool Diamond/Pearl Version-Exclusive Region-Creating Pokémon...

Oh yes, Mewtwo. I love him. Did I miss anyone? I don't know Diamond/Pearl so I'm sure I don't have all the ones from those versions.

Hoenn must be my favorite region. It's so beautiful and diverse. I once had a secret base in the desert, then in a bush, then in a rock, and hopefully someday in a tree.
