A new live action trailer further teases newly discovered Pokemon Meltan, which appears to be some bizarre metallic version of Ditto.  The end of the trailer also teases a possible evolved form which seems to be triggered by a large gathering of Meltan.

The new Pokemon will be making its game debut in both Pokemon Let’s Go Pikachu and Eevee and Pokemon GO, however the nature of its appearance and how it will be discovered in-game is still unknown.
