IMO:
Chiramii: Probably the 5th Gen's version of Rattata, but I feel like it might evolve into something somewhat useful, if not, at least cool looking.
Mun'na: My least favorite, but only because of the flowers. I mean, the pink is obnoxious, but the flowers are just too much for me. Again, it might evolve into something sweet.
Gear: I actually kinda like this one. I was thinking, perhaps it's the evolved version of Bronzoar? Give it metal coat, trade, and you have a Gear? Probably not, but there's always the possibility.
If not, the evolved version will likely have three or more gears. I like it for the fact that it's pure steel though.
Mamepato: Guaranteed the 5th Gen's Pidgey/Starly, who knows what the evolution will look like/be capable of.
Hihidaruma: Pretty good, actually. Like I said earlier, 5th Gen NEEDS more fire-type Pokemon, so hopefully we will get them. I'll probably catch one but it won't be on my team, most likely.
Shimama: My favorite of what has been revealed today! The only electric-type Pokemon I actually like is Manectric, but now I really like this one too. Plus I've wanted a zebra-like Pokemon for the longest.
Meguroko: A very close second favorite for today. I like that it is Ground/Dark, making it immune to Psychic and Electric. This one will probably be on my team as long as it's got good attacks, I'm all about picking the best type-pairing.
And I hope the second page has some more good information about the game, such as the villainous team. But I'm happy with what I've got
