I'm a relatively new player to Pokémon Go, but I do know the basics. That being said, I was out for a drive earlier today when I stumbled across a gym at a church with a pokémon that had a CP of over 48,000! Later, I found another gym with another 48,000 CP pokémon in it, and that's when I started wondering if I was missing something.
I researched in and out about gyms, but I was unable to find anything about these high-level CP pokémon. What are these high-CP pokémon?
