I really hope this is the first gen with an evil professor and possibly an evil (or at least Silver-esque) rival.
For one thing, they like strength. In Pokemon games, this is a sign that you are literally worse than the devil. The rival is all mysterious and shit, but he's a childhood friend, so I don't know if they'll go the anime route of an evil childhood friend or not but hey, whatever.
The professor, on the other hand, is just a Team boss waiting to happen. Look at this motherfucker. He's ~mysterious~ and you can't quite put your finger on him in addition to researching strength, strike 1. His name is apparently taken from "achromatic", which is just begging to be an evil pun so that's strike 2. Most damning of all, he looks like Albert Wesker, strike 3.
