This is Lunala, the Moone Pokemon.

It devours light, drawing a dark veil over the brightness of day.

Lunala's Darkness

Heheheh. Behold my power!

Oh no! The darkness is spreading!

*vwrwrwrwrrr*

Heheheh... It's showtime...!

It can watch movies outdoors, even during the day.

This one is pretty good.
