Black Bowser

Black Bowser appeared in 2016 video game called Paper Mario: Color Splash. Black Bowser (simply referred to in-game as Bowser) is the form Bowser took after he was possessed by black paint in Paper Mario: Color Splash. He serves as the final boss of the game.

At Port Prisma on Prism Island, various Toads were enjoying playing with the various colors of paint available. Bowser, who was looking from above, jumped into the rainbow-painted area in the middle of the Big Paint Stars with the intent of giving his shell a rainbow hue. However, his jumping around the paint caused him to inadvertently create black paint, which proceeded to possess Bowser (turning him into Black Bowser) into stealing the Big Paint Stars and ordering his minions to drain the island and its inhabitants of their color. As Black Bowser, he is more malevolent and mean-spirited than normal, willing even to drain Princess Peach's color out of annoyance after he catches her sending Mario messages, as well as making a dark joke after the fact when confronting Mario and mentioning his draining of Peach by saying she claimed she was "framed". In addition, his roar is slightly deeper and more warbled than normal.

After Mario and Huey retrieve the first Big Paint Star from Morton and return it to Port Prisma, Black Bowser appears and kidnaps Princess Peach, taking her to his castle on an airship.

Following the collection of the remaining Big Paint Stars, Mario and Huey go to Black Bowser's Castle via a kart ride from Luigi. Here, after overcoming some tribulations (including fighting Roy), Mario and Huey confront and eventually defeat Black Bowser, ridding him of the black paint and returning him to his normal self.
