Black Bowser

"Black Bowser is the villain in Paper Mario : Color Splash. When Bowser was at Port Prisma, he saw the Prisma Fountain with it's rainbow of colors and decided he wanted a rainbow colored shell. He jumps in and mixes all of the paint together while jumping around and created black paint. Then the black paint takes over Bowser and he becomes Black Bowser. He destroys the Big Paint Stars and has Slurp Guys suck out the paint of almost everything. After Mario and Huey find and save the Red Big Paint Star, Black Bowser is first shown in the vision that the Red Big Paint Star shows them. Then Bowser actually appears and takes Peach with him. Then the only time you see Bowser again before the final bosse battle is the visions the Big Paint Stars show Mario and Huey."
