The Tales of Transformation season debuts Mega Metagross in Pokemon GO as a Mega Raid Boss. Mega Metagross comes as a Mega Raid Boss during Raid Day events throughout the event. Those who win the Mega Raid get a guaranteed Metagross encounter, which can later Mega Evolve.

Those who already have a Metagross can Mega Evolve it into a Mega Metagross somewhere between the Tales of Transformation season. The Mega Pokemon will also start popping up as a Mega Raid Boss during the season’s events. Those who win these Mega Raids can encounter a High IV Metagross, which can later be a powerful Mega Metagross. That said, this guide details how to get Mega Metagross in Pokemon GO and Shiny Mega Metagross availability.

Those who win Pokemon GO Mega Metagross Raid get a guaranteed Metagross encounter. After catching a Metagross, you can then Mega Evolve it into a Mega Metagross. But winning a Mega Raid requires a team of 4 or more trainers with strategically selected counters.
