Yveltal's typing is not nearly as surprising as Xerneas, but to me both of them are pretty interesting. I think once fairy was released, it could have been inferred that Xerneas would be Fairy type, but no one would have guessed it to be pure. On the other hand, Yveltal looks the part of Dark/Flying, and its move Death Wing sounds pretty cool.
I'm glad that some variety was thrown into the Pancham line with its dual-dark typing and intense character creation. Koronda looks pretty menacing. I still won't be using him haha, but it's nice to see it won't be a boring Fighting type. Also interesting to see what the new way of evolution will be.
The squid typing is amazing, tbh. At first glance, everyone must've thought water, but their true typing is a shock and really intriguing as well. I can see Malamar becoming a powerhouse in competitive battle if its stats are to par with its odd type. On top of all the perks of the line, Maika is so darn cute!
Honestly, as long as Spritzee has a somewhat-good evolution, it's going on my team. I don't know why I like it so much, but along with Skrelp (who is also a Y-exclusive, lucky me), it's one of my favorite new fakemon. Can't wait to see its evolution details. As for the puffy pokemon, it looks cute but doesn't compare to the surperior fairy, imo haha.
The gym leaders both look wonderful! I'm guessing that the robotic-like man will be steel, and the nature-loving man to be rock type. No matter what specialty they turn out to be, I really enjoy their designs.
The professor is fine. I would've liked it to be another female professor, but for a male one, he is acceptable. I like the young, smart and motivated concept he has, and hopefully he'll have a similar aurora to his personality. I like him!
Team Flair/Flare is going to be odd; I really liked where they were going with the more universal evil team concepts, as they had began to move away from the elemental-based ones such as Magma and Aqua, which were too one-dimensonal in my opinion, but hopefully Team Flare proves me wrong.
