On the Rockruff/Starter "secret":
Now, this is speculation on my part, but hear me out. Earlier in the year CoroCoro stated that Rockruff and the starters share a secret, which in the coming months was assumed to be an exclusive Z-move, split evos, syncro-evos, etc. However, based on the descriptions that we got today of the middle starters, I would like to propose a different theory:
The starters (and Rockruff) do not evolve into their final stage based on level but based on a mechanic similar to Happiness if not happiness itself
The Evidence:
- "Lycanroc obeys its Trainer’s orders dutifully. In particular, if a Trainer accepted it during its more rebellious pre-Evolution period, Lycanroc will never ever betray that Trainer and will be the most loyal of partners." -Midday form
- "Contempt rises in this Pokémon for Trainers who give orders it doesn’t agree with or who try to force it to battle. On the other hand, it will feel a deep trust in a Trainer who can truly draw forth its power in battle." -Midnight Form
- "When it loses its focus, it sometimes even retires from the battle on the spot! It’s up to each Trainer to help Dartrix overcome this troublesome stage. If this Pokémon is with a Trainer who helps it through, its strength will grow hugely!" -Dartrix
- "Torracat has a great love for battle and will attack so relentlessly that its opponents lose the will to fight. And yet it sometimes behaves like spoiled child in front of Trainers or Pokémon with whom it has built a relationship of trust." -Torracat
- "Brionne always acts cheery and positive. Even when it’s feeling sad, this Pokémon doesn’t allow its sorrow to show. It’s said that Brionne will only reveal a sad expression to a Pokémon or Trainer to whom it has opened its heart completely." -Brionne
All of these descriptions heavily emphasize the trust and loyalty that a pokemon needs to develop to its Trainer, and Pokemon has always stressed that relationship building and friendship are the goal of the games, and not so much winning every battle. Now, in previous gens I would say that such a theory would be ridiculous because it ignores precedent, but as we all know by now, Sun and Moon doesn't really care about that (i.e. no gyms). And numerous other Pokemon evolve based on knowing a certain move, holding a certain item, Happiness, etc. so why not the starters? Maybe after 20 years Pokemon has finally grown tired of the first evo at lvl 14-16, second evo at lvl 36. In my opinion, it would add alot to the immersion experience if we have to care for our pokemon's Happiness, Trust Meter, etc. rather than tossing it out to grind.
