It may appear to be smaller than previous regions, but you've got to consider the fact that Alola is split into four separate islands. Each island appears to have a variety of different towns and explorable areas to discover, just like any other region.
Lusamine is the champion and she is evil in the plot~~~ ^^
According to a leak , Alolan Blue is the champion of Alola.
However, I'd imagine it won't happen since the Champion is meant to mostly appear as a mentor figure who you encounter a few times before their Champion battle.
That actually reminds me, would the fifth island count towards the island trails? I mean, it's not the same as the other islands and only really exists to host the Aether Paradise, so I don't think so, I don't think it even has a guardian Pokemon.
Hard to say. Thanks to Sina and Dexio we know that XY takes place before Sun and Moon, meaning that the backpacker's comment on their Champion is also before Sun and Moon, so we can probably rule out Hau or Gladion becoming Champion. Probably some other character we'll see in the game.edit: speaking of, does anyone else have an idea of who can possibly be the champion of this region?
Well to this point Hau or Lusamine or Kukui, either is fine as a Champion for me, because I don't want another Diantha :/ sorry Diantha, you're elegant and all but for a champion to not involve in the major plot is very upsetting, and I don't care about your movie star status (XY anime she did appeared, kudos to anime department LOL)
p/s: I guess Iris did the same stuff too, meh... :/
