A New Mythical Pokemon Has Been Revealed

The Pokemon Company has officially revealed the final "Gen 7" Pokemon, Marshadow. In a trailer released early this morning, the Pokemon Company finally acknowledged the Pokemon's existence, but declined to release any other details about the Pokemon. You can check out the official reveal trailer below:
Marshadow will have some sort of role to play in the upcoming Pokemon the Movie: I Choose You, as it lives in Ash Ketchum's shadow. The plot focuses on Ash trying to find Ho-Oh, the Legendary Pokemon he saw on the first day of his Pokemon journey 20 years ago.
While we don't have any "official" details about Marshadow, a datamine of Pokemon Sun and Moon revealed tons of info about the new Mythical Pokemon last month. Marshadow is a Ghost/Fighting dual-type Pokemon and is known as the "Gloomdweller" Pokemon. As seen in the movie trailer, Marshadow lives in the shadows of others and has hid its existence from humans for years.
Marshadow's Signature move is "Spectral Thief," a Ghost-Type move that deals out physical damage and also steals an opponent's stat boosts. It can also use the unique Z-Move "Soul-Stealing 7-Star Strike."
It's a bit of a surprise that the Pokemon Company revealed Marshadow already, especially as its the last unrevealed Pokemon for the latest generation of games.
There's been no official word on how players can get Marshadow for Pokemon Sun and Moon, but it will likely be tied to a distribution tied to the release of Pokemon the Movie: I Choose You later this year.
