Hey guys, I thought it might be fun to start a threat of the week here on Perfect Pokemon. In this thread, we will discuss a new threat each week. This includes talking about counters, checks, cores, sets, and everything in between. If you have anything to say about a particular Pokemon this is the place to say it. I will try to highlight strong threats for as long as possible and potentially revisit threats as new sets and tier changes come out. Since this is a relatively new thread, I'll try to keep it OU only for the time being, but this may change as time goes on. To get things started, let's talk about a somewhat controversial Pokemon for the first week: Greninja. This true terror of OU sports an amazing speed, a great movepool, and one of the best abilities in the game. Greninja's combination of mixed offenses, a movepool that many Pokemon would kill for, and STAB on every attack via Protean make for a deadly cleaner that few teams can properly prepare for. If you see a Greninja on the opposing team, make sure you have a gameplan for it or else you could find yourself slowly losing Pokemon after Pokemon to it in a frantic attempt to learn it's moveset.
