Pokemon Go just nerfed the stats of a powerful Legendary Pokemon, right before its potential addition to the game.

Yesterday, game developers made several tweaks to the GAME_MASTER file in preparation of the upcoming Halloween event. While most of the changes were related to new Pokemon, dataminers noticed that Pokemon Go also tinkered with the stats of Ho-Oh, the only Gen 1/Gen 2 Legendary Pokemon that hasn't been released in the game yet.

Ho-Oh's base stats were all decreased by 9%, dropping its max CP from 4650 to 3889. This means that Ho-Oh's no longer the most powerful potential Pokemon in Pokemon Go, as it now has a lower CP than Mewtwo, whose stats were also nerfed over the summer.

With the decreases, Ho-Oh's Stamina is now 193, its Attack is now 239, and its Defense is now 274. These are all pretty great stats....just not as great as they were a few days ago.
