Black is the opposite of White in MIKAN Marble Race and he loves to beat the race and win all the time with his best friends and he is darker than Gray and his best friend White but sometimes he gets eliminated in any stage whenever he dies.
Black: Hey guys, My name is Black and I am the opposite of White! And this is my best friend, White! White and I are the opposite colours, because White is different than mine! White and I mix to make Gray! I am darker than Gray, and I am more darker than White, and that makes me black!
