I've written down my thoughts on each Pokemon and given them a score out of 10. Most of this batch was good and there were only a few that I didn't like. I've also included the new Pokemon and Alola forms leaked a few hours ago.
---
Yowashi - Love it. The designs are awesome for both forms and I really like the idea behind them as well. Can't wait to see this one in-game. 6/10 - Win
Nuikoguma - Bewear is one of my favourite Alola Pokemon so far, so it is no surprise that I love this little guy as well. I mean, c'mon it's adorable. So far this batch of new mons has been great. 8/10 - Win
Sunaba - Strange idea for a Pokemon, but I really dig (pun intended) the design for this one. I love how they have made it look a bit like a ghost to fit in with it's Ghost typing. 7/10 - Win
Shirodesuna - No, just no. Unlike Sunaba, I do not like the design for Shirodesuna at all. I find it's face to be really weird looking for some reason, and there are a few other things that really bug me about the design but I I'm not sure exactly what they are. 2/10 - Fail
Pyukumuku - An adorable Sea Cucumber that spews out it's guts and fights with them? Sign me up! 6/10 - Win
Morelull - Damn Game Freak you're doing great with these Gen 7 Pokemon designs so far. I love this one as well, and I like the typing they have given it. 7/10 - Win
Alolan Marowak - I wanted to like this one, I really did guys, but something about it's design I can't stand. I think it's the fact that they have made it's body look so scrawny that it looks out of proportion with it's head. I also feel like this is another one of those 'SUPER EDGY!!' Pokemon, like Mega Charizard X. I do like the typing and the green-blue flames though. 3/10 - Fail. To much Edge.
Alolan Meowth - I like this one, even if it doesn't change to much in design from regular Meowth. I like the choice of grey colouring and the Dark typing as well. Oh, and it's smug expression as well, how could I forget that? I love smug Pokemon. 6/10 - Win
Alolan Raichu - Upon first glance I really didn't like it since I thought it just looked like a rounded Raichu, but after seeing it's typing and the surfing idea behind it I like it a lot more now. I don't really have anything else to say about Alolan Raichu other than I can't wait to see it in-game. 5/10 - Mixed (mostly a win though).
