My teams? Can't remember what I used before, but here's my Sun team:
Primarina (Pearly - F): Just too cute for me to resist. Seriously, has anyone given Brionne or Primarina beans? They're just too adorable!! My favourite of this generation hands down
Toucannon (Pecko - M): Didn't think I'd keep him, hence the lame name. Turned out to be absurdly strong!
Marblepie (Lycanroc - F): Same as Pecko, I saw pure Rock, thought "meh" but was lacking a 6th Pokémon. Now she's my second favourite of this generation! Prob should rename her, though.
Sawbeet (Ribombee - F): Such a cute wittle bee! And so I tried to find a name and came up with that pun... Kinda wish they made a Pokémon out of that name, curious to see what that'd give. Too bad she's getting too weak to sweep the story by now.
Petahlia (Lurantis - F): Just loved her design. Pure plant and poor offensive type coverage coupled with low speed makes her rather bad but hey, who cares? Skin before skill! And who could resist to her great looks?
Last slot will be taken by either a Salazzle or an Alolan Ninetales. Haven't decided on a name for either yet. There's also 3 Pokémon I used to battle with but eventually parted with, and so, time for honourable mentions:
Wishiwashi - M: This one doesn't have a nickname because it was weak and without evolution. Then I battle the Totem Pokémon and fell in love with it. My third favourite Pokémon of this generation! Alas, already had a water Pokémon, but I'll use him again.
Charjbug (Airzap - M): Yup, not fully evolved. This one should have been in my team instead of Sawbeet but for some reason, GameFreak decided it was a great idea to have a bug-type pokémon aquired at the start of the game evolve only when you're nearing the end of the game.
Gumshoos (Munchacho - M): He had a good run, but with Pecko and Marblepie in my team, there was nothing he could actually bring. Sorry Munchacho, at least I got you to evolve.
And finally, my number one Pokémon, all generations included, the Pokémon I care for the most:
Mawile (Little Fey - F): I have no idea why but from the first time I saw her, I fell in love with the design. However, I never could quite use her because of low stats and a rather poor pool of moves... To my greatest joy, this changed with the introduction of the Fairy-type - giving her access to Play Rough - and of course, with that of the Mega Evolution! Ahhh, can't wait to welcome her to Alola!
