Mamoru Chiba, better known as Tuxedo Mask is a fictional character and one of the primary protagonists of the Sailor Moon media franchise created by Naoko Takeuchi. He disguises himself in order to support the series' central heroines, the Sailor Soldiers. Wearing a mask to conceal his identity, he interferes with enemy operations, offers the Sailor Soldiers advice, and sometimes physically aids them in battle. Like the Sailor Soldiers, Tuxedo Mask possesses a power item like theirs: a Sailor Crystal, which gives him guardianship over the planet Earth. He also has psychic powers, including psychometry and healing, which evolve and become important to the storyline in the manga, but which play only a minor role and remain static in the anime. Along with his primary love interest Sailor Moon, a significant player in much of the story, he has royal credentials in the "past life" storyline as well as in the future. Chibiusa and Usagi, in particular, commonly refer to him with the nickname "Mamo-chan". The DIC and Cloverway English adaptation often shortens his name, "Darien," to "Dar" as a nickname; however, this happens inconsistently.
