Now this was a TRALIER! Gotta say its funny that the region is called Aloha, but makes sense seeing as its Hawaii! The game itself also appears to be improved in terms of in game models and scales - no more chibi models! As for the starters, they're pretty good and simple looking, but depending on the reactions of most people so far on other forums, the impressions look to be average so far.
However, I will repeat what I said when I came to this site for the first time. The starters shouldn't be judged on appearance alone, as these are just the first forms of them. There's more to them than just appearance and it will take a while for people to warm up to them. For me, personally, I think they look pretty unique for designs - they're neither too safe, nor too predictable looking. They look wacky and funny to me, especially when it comes to the Grass Owl. I'm pretty sure someone out there is going to make a scary meme with that owl's stare. In terms of ranking:
1. Rowlet (Grass/Flying) - its facial expression is just too funny and weird based on the official art I have just seen.
2. Popplio (Water) - Has the most unique appearance of all three, combining a clown, a puppy dog and a seal in one form. Its very nicely done, so second place.
3. Litten (Fire) - At first appearance, it looks borish in a way as if has no mood to do anything, hence why I'm putting it third place despite my love for cats.
Despite the rankings, this does not determine which one I would go choose ultimately. My ultimate choice will likely fall with the direction of their second evolutions, whatever they are. Although its your free choice, I imply to people to not get too attached to any fan-art that will pop up in the following days and months to come, and keep your expectations low as possible so you can have a more open mind to their true designs whenever they get revealed in the near future.
As for the Legends, its a pity to see my theory in terms of design didn't pan out, but I really like the designs themselves. Being a cat lover by nature, I really love Solgaleo's design. Its not the usual red-colored scheme, and its facial design is pretty ace. The Bat Legendary is pretty unique in terms of appearance, having a more cosmic feel to it than the lion, but looks a bit over-designed in my opinion, whereas the lion is more simple and straight forward, but the Bat does appear to be feminine in some ways, especially how it sounds.
As for their typings, well, its easy to say and a safe guess that Solgaleo is going to be a Fire-type. That much is obvious. The Moon Legendary, however, isn't as predictable. From what I have seen now, its safe to guess this lady bat isn't going to be a Water-type as I commonly guessed at first. Based on this knowledge, my final predictions for their types of either Legendary will be either of the following:
Moon Legendary - Lunaala
Going to be either a Dark/Fairy or Fairy/Flying. I'm personally still hoping on a Water/Flying or Water/Fairy, but I highly doubt it. However, Pokémon Pearl's mascot - Palkia, wasn't exactly screaming Water-type either, and it still ended up being a Water/Dragon, so who knows?
Sun Legendary - Solgaleo
For super safe predictions I'm putting money on the lion being either Fire/Fairy or Fire/Electric. However, what is also possible, is that the Sun Legendary could be our first Fire/Grass type. This third guess is mainly based on the fact that its mane is extremely detailed, moreso than the rest of its design, having a clear hawaiian flower shape to me, and in the form of a star no less. As Hawaii has a lot to do with flowers, it makes sense to make the Legendary itself fit more with the tropical theme of the region. Third, lions live in the savannah, which is a grassland-type habitat, and lastly, Grass types in general always learn Solarbeam. Based on these ideas, I really hope this guy ends up being a Fire/Grass type in the end.
That said, ultimately, I would be fine with any of the speculated typing I just put out, as each combination is still brand new and unused (except for Water/Fairy, Water/Flying), so its refreshing at the very least. Coming to the choice of which version I want...well, I will be going for Sun this time ahead, as its Legendary Mascot really appeals to me, not to say, Leo is my birth zodiac sign, so the choice is pretty obvious. My choices, however, could still change depending on the exclusives themselves.
For now, I'm pretty content with what we have. Come on with the new theories!
