Generally, players will have to wait for special events to encounter some of these Pokemon. For example, Aerodactyl will be a three-star Raid Boss in the Mythic Blade event.Getting Mystery Box and encountering Meltan (Image via Pokemon GO)The second method of getting a Meltan in Pokemon GO is through Mystery Boxes. Players can get their hands on a Mystery Box by sending a pocket monster from the AR title to Pokemon: Let's GO, Pikachu! or Pokemon: Let's GO, Eevee! The official website mentions that players will receive a Mystery Box by sending Pokemon to a friend's Nintendo Switch game.Furthermore, it also states that the box can only be opened again after players have waited for a certain period of time and then again set another Pokemon to either of the two games mentioned above.The easiest option for players is to download Pokemon HOME on their smartphone, connect it with Pokemon GO to their Nintendo account, and transfer a Pokemon from the latter to the former to get this unique in-game item. After this process, the Mystery Box will be waiting for players in their Bag.Once the Mystery Box is opened in Pokemon GO, players will be able to see Meltan spawning on their world map for an hour. Players will need to quickly catch them and it's advised they do so with Pinap Berries. Evolving this Pokemon to Melmetal is also a difficult task, as the Hex Nut Pokemon requires 400 Meltan Candies to evolve.According to Bulbapedia, Meltan has a catch rate of 1.6%. Players should keep a fair number of Great Balls and Ultra Balls in their inventory, along with Pinap Berries and Silver Pinap Berries.
