Brooklyn's Nick Johnson may have just become the world's first Pokémon Go grandmaster. He had previously snagged all 142 Pokémon available in the United States, but that wasn't enough for a true master. He left about a week ago to travel the world and complete his Pokédex.
In addition to the 142 Pokémon he had already captured, there are four Pokémon only available in specific regions of the world, making a journey of this nature necessary for any completist Pokémon Go player. (Though Niantic has not officially confirmed these are regionally specific, it has basically been confirmed by users around the world.) With a trip to Paris, Hong Kong and Sydney, Johnson has managed to accomplish what some thought impossible, and others hadn't really considered doing.
It seems like a crazy thing to do, taking a whirlwind trip across the globe to capture Pokémon, but worthwhile when Marriott was covering his accommodations and Expedia paid for the airfare.
