Meltan, the recently revealed new Mythical Pokemon, has been shrouded in mystery since it first (sort of) appeared in Pokemon Go following September's Community Day event, but now we've learned a lot more about it. The Pokemon Company has revealed some new details about Meltan, the most tantalizing of which is a hint at a possible second form for the Hex Nut Pokemon.

The company revealed the details via two new trailers revolving around Meltan. The first is the second installment of the Two Professors video series, featuring Professors Oak and Willow discussing the new information they learned about the Pokemon, including how players can acquire it. The second, which you can watch below, is a promotional trailer showing off a group of Meltan mischievously playing with different items around a house.
