Alright guys and girls, we have seen multiple Alolan forms so far and it appears that they are mostly there to put Dark type into Gen1 and Ice type on non-Ice things.
(disclaimer: I really like them, though)
So far they mostly made a lot of sense and brought some fresh air into the old and stale designs. And now with Grimer even one of the most simplistic Kantomons got a good makeover. (is that a skull peeking out there?)
What are your ideas for more Alolan forms? Unfortunately, things like Lapras, Fearow, Primeape, Psyduck, Machamp, Arcanine, Relaxo, Tauros and Dragonite have already been somewhat confirmed to not receive a new form.
Hula Water/Psychic Jynx
Kappa² Water/Grass Golduck
Electrode turning into a spirit orb (Ghost) or a different kind of Pokéball (Dive Ball?)
Alley-lurking Psychic/Dark Drowzee/Hypno
Cosmic Fairy/Psychic or Fairy/Ghost Clefable/Clefairy HAVE to happen. Willing to bet money on it. As fellow Hawaii researchers, we know how important celestial and astronomic exploration and superstition is to Hawaii. And with one of world's most prominent observatories being stationed on Hawaii and the recurring spacemon trope, this would be an oddly missed chance were they not to do it.
