Black Directive (ブラック指令 Burakku Shirei?), also known as Commander Black, is the final antagonist of the TV Series, Ultraman Leo. Up to the episode before his introduction, Ultraman Leo lacked any true major antagonist (with the exception of the Alien Magmas), so it is likely that Black Directive was introduced to fulfil this role. He is the commander of the saucer beasts who hoped to destroy Ultraman Leo and to conquer the Earth, but ultimately failed after the defeat of Black End.
