What do you get when a wild mew grows up trapped in a lightless cave for the majority of it's thirty-seven years of life?

Adaptation.

Born of darkness and eyes of darkness, this is Maelstrom. He is blind, but so immensely sensitive to his surroundings that he sees sight as a limitation. One that is easily manipulated. Bold, confident, and ironically loud, he is a master of the rapid-fire Shadow Ball and has refined it so densely that hitting his targets enduce blindness upon them. His signature move, Black Abyss, covers an entire field of immense black fog that not even infrared and x-ray can pierce. The perfect smokescreen.
