Pulseman?
You heard it here first folks
While I would agree that's a good guess, it doesn't look like Pulseman.
I'm hoping this is the equivalent of a game like Harvest Moon (not necessarily the same gameplay just stick with me for a moment) and this silhouette is a new Pokemon, that will play a part in that Harvest Moon Game.
Imagine for a moment it would be like Animal Crossing, but you get to ride a Gogoat. Hence this would be revealing Gogoat, but more to the point of it playing a role in this brand new game, not entirely related to Pokemon.
