Revered long ago for its capacity to create iron from nothing, for some reason it has come back to life after 3,000 years.
– Pokémon Let’s Go Eevee Pokédex
Melmetal evolves from Meltan, but it can only be evolved in Pokemon Go, using 400 Meltan Candy. It can then be transferred to Pokemon Let’s Go Pikachu and Let’s Go Eevee.
I started playing Pokemon Go again after a long hiatus, in order to get Melmetal. 400 candies is a lot. I think I used a bunch of Pinap berries to help double the candy output. Also I was playing around Christmas and there was a double candy event for one week, so I was getting 4x candy.
Stat-wise, it has high Attack and Defense, as well as good HP. It has very low Speed however. It has a signature move in Let’s Go, called Double Iron Bash, which is multi-hit (double) move that has a 30% chance to cause flinching
