Here's my official predictions:
| Pokémon | Type |
| 1. Stantler | Ice/Psychic |
| 2. Dunsparce | Bug/Dragon |
| 3. Cacturne | Grass/Fire |
| 4. Hariyama | Ground/Fighting |
| 5. Pachirisu | Ice/Electric |
| 6. Mismagius (+ Misdreavus) |
Ghost/Fairy |
| 7. Delcatty (+ Skitty) | Normal/Fairy |
| 8. Seviper | Poison/Steel |
| 9. Zangoose | Fighting/Fairy |
| 10. Masquerain | Bug/Water |
And here are some others, that aren't part of my prediction:
All fossil pokemon other than Aerodactyl (perhaps they're still alive on Alola? Aerodactyl is a special case because it has a mega form): Kabuto/Kabutops (Bug/Steel), Omanyte/Omastar (Bug/Psychic), Lileep/Cradily (Grass/Ghost), Anorith/Armaldo (Steel/Dragon), Rampardos (Ground/Fighting), Shieldon/Bastiodon (Steel/Grass), Tirtouga/Carracosta (Fire/Water), Archen/Archeops (Poison/Flying), Tyrunt/Tyrantrum (Dragon), Amaura/Aurorus (Fire/Fairy).
Other pokemon: Vibrava/Flygon (Bug/Dragon - Trapinch being Bug/Ground), Victreebel line (Grass/Flying), Torkoal (Fire/Ice), Unown (Dark), Relicanth (Water/Ground), Spiritomb (Ghost/Fairy), Girafarig (Psychic/Dark), Farfetch'd (Normal/Fighting), Cryogonal (Rock), Volbeat/Illumise (Bug/Fire).
A few to specifically talk about - Stantler gets a Christmas makeover, Masquerain becomes the true water bug it was supposed to be, Victreebel line's leaves become more functional, Unown in the area have been corrupted somewhat, Relicanth had to be softer in a place where more humans wander into the water, Girafarig's tail becomes stronger, Spiritomb's spirits have been calmed, Farfetch'd gets more expertise with its vegetable (probably not a Leek in Alola), Cryogonal needed a tougher material so it's Crystal instead of Ice, and Volbeat/Illumise's tails become a lot hotter.
For the fossils, a few need some explanation. Lileep/Cradily are actually the black things inside the bulbs of the plants, so I'm picturing them becoming more dominant to replace the Rock tping, so I went with Grass/Ghost. Rampardos needed typing that still suited its basic design, so Ground/Fighting. Shieldon/Bastiodon are based on herbivores, so I figured I'd go with that. Tirtouga/Carracosta needed something to replace the Rock, and I figured Fire would be interesting. Archen/Archeops look like snakes with wings, so I followed that logic. Amaura/Aurorus reverse the transition seen with Vulpix/Ninetales.
It's actually quite fun to imagine possibilities. For instance, maybe Doduo/Dodrio become real flying pokemon (wings go from tiny and nonfunctional to real wings), perhaps as Fighting/Flying? Maybe Ekans/Arbok could be Poison/Dragons? Maybe Hoothoot/Noctowl could get the Psychic types they always deserved? Maybe Lickitung and Lickilicky could be Normal/Poison because of their diet in Alola? Maybe Milotic could be a Dragon type?
Oh, and what if Spiky-eared Pichu comes from Alola? Perhaps it could show up, with evolutions having special typing? A Pikachu with a few visual tweaks, with typing Electric/Grass, maybe?
