There were reports all over Reddit, Twitch, and other networks of players reporting they got their hands on Legenday Pokemon, the most common one being Articuno. Players were trying to “prove” themselves with live gameplay and reasoning, but many players obviously doubted the truth behind it. Especially since the stories regarding how they got the Pokemon were not lining up.
As it turns out, they really did have the Pokemon. Developed Niantic revealed today that the pokemon “mistakenly got added to some users profiles.” They didn’t explain how the players came across the Pokemon, or what error caused it, but they followed up by stating the Pokemon have been removed.
“We recently noticed that a few Legendary Pokemon got into a few accounts when they shouldn’t have, To preserve the game’s integrity and as a measure of fairness, we have rectified the situation and revoked the legendary Pokemon from the Trainers’ accounts.”
Based on these words it doesn’t appear the players hacked into the game to gain the Pokemon, and instead it was some type of error. As of writing this Niantic has yet to release any Legendary Pokemon in the game officially.
The Pokemon were, of course, listed in multiple gyms and players were live streaming using them. Many players were questioning the intregrity due to the low stat count many of them had. Niantic hasn’t stated if this will represent the actual release.
