all this hate on froakie over the internet and on earlier pages in this topic
let me take you on a trip down memory lane
Squirtle, a small squirrel turtle hybrid, turns into Blastoise, some sort of army cannon turtle that will blow your brains out
Totodile, a tiny crocodile with a sad bite, turns into Feraligatr, a massive crocodile type pokemon with a badass name that will rip your brains out
Mudkip, the annoyingly cute pokemon that started a crappy internet meme, turns into Swampert, some sort of swimming, wrestling, badass pokemon with anger issues who will stamp your brains out
Piplup, the cute little penguin, who only wishes to love and adore you, turns into Empoleon, possibly the most badass penguin with some sort of pointy trident on his head who will drill your brains out
and Oshawatt, the tiny little ugly otter, who turns into Samurott, some badass samurai sealion otter hybrid with a badass sword on his head who will stab your brains out
my prediction
Froakie will be some sort of cute, innocent badly designed pokemon, who will turn into some epic giant toad with a badass attitude which will try to remove your brains from your body one way or another.
