The Pokemon Company has just released two brand new trailers for the new Mythical Pokemon Meltan. At the end of one of these trailers, it appears that the Pokemon Company is teasing either an evolution, or a whole new form for Meltan.
This comes right at the end of the trailer, where all the Meltan are cuddling together only for the screen to go white and a shadow to appear. The trailer then ends with “I think Meltan still holds a greater secret to be uncovered.”
