Gothitelle

Gothitelle also has a torrid history of descriptions. In Black & White 2, it was said, “It can see the future from the movement of the stars. When it learns its Trainer’s life span, it cries in sadness.”
By Shield this got even weirder with, “A criminal who was shown his fate by a Gothitelle went missing that same day and was never seen again.”
But that’s as nothing compared to the new version of Gothitelle’s apparent living hell, this cursed Cassandra’s nightmare extending way beyond the end of a Trainer’s life.
In Scarlet we’re told:
Gothitelle unleashes psychic energy and shows opponents dreams of the universe’s end. These dreams are apparently ethereal and beautiful.
But in Violet all that sad beauty is replaced with:
It gazes at the stars to predict the future. It acts somewhat detached because it has seen the end of all existence.
Brrrrrrrrrr.
