Fennekin is an all right Pokémon—it's quite cute. I'm not very fond of its final-stage evolution though, Delphox. When it was first announced, people thought that it would be based on a witch, but in actuality, it wasn't. Instead, it ended up looking more like a priestess. d: Not that I dislike the concept or anything, but I think Delphox would've looked a whole lot better if it actually turned out to be a witch as people had expected.
Froakie is not that bad. Out of the three starters, this has gotta be second favorite. They've done a great job at making Greninja look like a ninja. It does quite look like one, doesn't it? Also, I love how they made its tongue act as a scarf—it's very creative! On the battling side of things, it has great Speed, and its offenses seem to be well-balanced. If you utilize it the right way, then this Pokémon could make a great revenge killer for almost any of your team.
My most favorite starter of all would have to Chespin. Chespin is one of the most adorable Pokémon I ever laid my eyes on. Many people may find Quilladin, its second-stage evolution, to be a little bad looking, but I personally don't mind it. It might look like a volleyball, but the Pokémon is pretty gigantic. It's got a lot of bulk. Its final-stage, Chesnaught, is absolutely monstrous, which I really like! Its facial expression may not be too intimidating, but the design of its body is just… wow. o: Stats-wise, it has great Attack and Defense. Its base Attack stat is one-o-seven, which is certainly above-average. Its Defense stat is equal to approximately one-twenty, and with that amount, it should be able to take up to ten to twenty hits in a row without fainting. That, in my opinion, is pretty impressive! :)
