Mamoru Chiba is the reincarnation of Prince Endymion and Usagi Tsukino's love interest. He is the civilian identity of Tuxedo Mask. In the 30th century, he will be known as King Endymion. He is the future father of Chibiusa Tsukino. This is the original depiction of the manga character created by Naoko Takeuchi.
At a young age he lost his parents in a car crash on his 6th Brithday. This blocked his childhood memories of his current lifetime and opened up the memories of his previous life as Prince Endymion. In the beginning of the series, dreams of Princess Serenity haunt Mamoru. Unaware of his dual-identity as Tuxedo Mask, he suffers painful headaches and visions whenever Usagi gets into trouble, and he transforms unknowingly into Tuxedo Mask. As Mamoru, he tries to piece together his strange dreams, and as Tuxedo Mask, he tries to remember his past and identity, while searching for Princess Serenity. He seeks the Silver Crystal in the belief that this will fully restore his memories.
The manga develops Mamoru extensively, showing that the car-crash happened on his birthday, and it gives a glimpse of his parents. Mamoru also struggles with his identity and function throughout the manga, worrying first about his true nature, then later whether he gets in the way of the Sailor Senshi. A fair amount of subtle characterization is made for Mamoru, and later extending his role within the manga as to who he is. He also is given the power of psychometry. This manifests in his ability to see and read dreams (such as Chibiusa's), heal people and monitor the status of the Earth. This was not fully developed until the second season, and was used occasionally throughout the series.
The manga tends to show Mamoru as quiet, studious, mysterious and stoic. The student body of his high school often admires him for these qualities.
Mamoru is an adult male who has black hair and deep blue eyes. He stands at about 175 cm or 5 feet 9 inches, and his left ear is pierced.
Mamoru first appears in Act 1. Depressed over her bad grade, Usagi crumples her test up into a ball and throw it over her shoulder, only for it to accidentaly land in his face. He calls her "bump head" and asks if she is trying to put bumps on his head. She angrily protests that they are dumpling buns, not bumps. He mocks her for only scoring 30 points on the test, and throws the paper back in her face, saying that she needs to study more. Usagi angrily says that he needs to mind his own buisness, and also notes that he rather strange for wearing a tuxedo in the middle of the days. She calls him a "snobby jerk" and walks away. The man exclaims that OSA-P is a rather large jewelry store, and that it might hold the "Silver Crystal".
His name, just like the girls', carries a pun. His surname "Chiba" means local and contains the kanji 地 (chi) which also appears in the word "Chikyuu", the Japanese name for Earth and 場 (ba), meaning place or location. His given name "Mamoru" (衛) means to protect. So the pun in his name is loosely "Earth Protector", "Local Protector", or simply "Protector of Earth".
- Of all the characters, Mamoru gets brainwashed and captured the most throughout the series, probably because of his importance to Usagi. Mamoru was kidnapped and brainwashed by the Dark Kingdom and Black Lady. Mamoru is killed then brought back (along with the Sailor Senshi) under the control of Sailor Galaxia.
- His name 'Mamoru Chiba' is similar to the name "Mamoru Chino," the prototypical name for Makoto Kino.
- Mamoru displays healing abilities without becoming Tuxedo Mask.
- Mamoru's birthday falls on August 3rd, which means he is a Leo. The zodiac sign of Leo is ruled by the Sun.
