I'm surely not going to put them in a box. Litten looks the cutest, and just makes me want him more than ever.
That said though, putting PKMN in a box isn't as bad anymore with Poke Pelago on the horizon.
I'm still choosing Litten over the others. Brionne I see becoming a Fairy and I hate that tyoe, meanwhile Rowlett kept that ugly nose.
Litten stayed good looking, just hope he grows the Dark type and not Fighting. We need a NEW Pokemon that has Dark typing
Litten's final evo must be fire and dark. We need a new dark type
Interesting. Now add to this that Dartrix, Torracat and Brionne all have in their description something about how they will act only if they get very close to their trainer and I'm pretty sure there will be more special scenes with the starter.
Unless this means the game would force you to keep your starter in your party.
Well it better not, haha, that would be one change that would not go down well with a LOT of people.
But I really think the whole "does this pokemon really want to come with you on the journey?" bit is just a bit of flavour that won't effect anything later on.
