MamoUsa

MamoUsa is the het ship between Usagi Tsukino and Mamoru Chiba from the Sailor Moon fandom.

Manga
At some point in the distant past, during the Silver Millennium, Princess Serenity of the Moon and Prince Endymion of the Earth fell in love. So much so that the Princess would set up distractions so she could sneak off to Earth to see the Prince. An alien species invaded the Earth, turning the residents evil, except Prince Endymion. The Earth dwellers raged war on the Moon, and Endymion tried to save his people, but it was too late and he was killed by them. Grieved by his death, Princess Serenity committed suicide.

Dark Kingdom Arc
They are reborn in the 20th century as Usagi Tsukino and Mamoru Chiba. They don't get along as civilians, but Sailor Moon becomes absolutely smitten with Tuxedo Mask, who frequently helps when she fights an enemy. Tuxedo Mask then reaches out to the news press to help him find the Silver Crystal, so they put out an article. The Dark Kingdom takes advantage of this, and puts out brainwashing waves so people will search for the Crystal. Usagi falls under the spell, and while walking outside, falls unconscious. Mamoru wakes her up by holding her wrist, and apologizes that his actions led to this. He knows she's Sailor Moon, and tells her to transform because she's the only one who can save the city. After healing everyone with the Moon Stick, she falls unconscious again, so Mamoru carries her to his apartment.

She wakes up, and makes the connection that he is Tuxedo Mask. Mamoru explains his actions with his past, then Usagi goes to leave. From there on, they start calling each other "Usako" and "Mamo-chan".

Kunzite attacks the city, causing a blackout, so the Senshi go to investigate at the top of Tokyo Tower. Kunzite absorbs the energy from their attacks, then fires it at Sailor Moon. Tuxedo Mask takes the blast for her, and begins to regain his memories. Sailor Moon awakens as the Moon Princess and all their memories during the Silver Millennium are revived. Her tears become the Legendary Silver Crystal, and part of it enters Tuxedo Mask's body. Kunzite then captures Tuxedo Mask and disappears. He is brainwashed and attacks the command centre. Venus kills Beryl there, but falls unconscious. Tuxedo Mask picks her up, and Sailor Moon chases after them.

After being battered by Tuxedo Mask, she feels she can't bear to see Mamoru act like this anymore, and stabs herself with Venus's sword. The Silver Crystal forms a casing around them, which is absorbed by Metalia. Usagi awakens to find that the sword caught on Mamoru's pocket watch. Tuxedo Mask gives Sailor Moon more strength, and she seals Metalia away. Luna asks Usagi to come the moon, so Mamoru and Usagi combine their power to travel there. Usagi is given a new brooch that will give her more power. She transforms and uses "Moon Healing Escalation" to turn the Earth completely back to normal.

Black Moon Arc
After school, Usagi meets with Mamoru. She gives him back his pocket watch, which she had restored. The two kiss, when some child falls from the sky and knocks Usagi away. She is enraged and wants to know who that is clinging onto her Mamo-chan.

90's Anime
At some point in the distant past, Princess Serenity of the Moon and Prince Endymion of the Earth fell in love. One day, the prince visited the princess to warn her of the Earth's plans to go to war with the Moon. Later, the Earth people attacked the Moon. Endymion tried to protect Serenity, but both were killed.

Using the power of the Legendary Silver Crystal, they were sent into the 20th century and reborn as Usagi Tsukino and Mamoru Chiba. At first they don't get along well at all, and often bicker with each other, sometimes downright insulting each other.

Mamoru takes on the identity of Tuxedo Mask to look for the Silver Crystal for keys to his past since he lost his memories in a car crash. Usagi is awakened by Luna as Sailor Moon to fight the Dark Kingdom. Zoisite challenges Mamoru to a duel to see who gets to keep all the Rainbow Crystals. Usagi chases after Mamoru because she is worried he's hurt from a previous battle, and ends up getting involved. Zoisite cheats and stabs Mamoru from behind, and causes the building to start collapsing on them. The two run into an elevator, but Zoisite lights a fire from above. Usagi knows that unless she transforms, they'll die, but then Mamoru will know she's Sailor Moon. She decides to transform in front of Mamoru and escapes danger.

As time goes on, Usagi learns she is the princess. Mamoru is captured and brainwashed into evil by Queen Beryl who rules the Dark Kingdom. Usagi misses him greatly and frequently has nightmares about it. She often listens to his music box when she needs cheering up. Eventually, Sailor Moon and the Senshi confront the Dark Kingdom at D-Point. Sailor Moon finally heals him back to normal with the Moon Stick. Mamoru gets attacked by Queen Beryl and dies. Sailor Moon goes on to defeat Beyrl, but also dies. However, by miracles, they return to their previous life, but with no memories of their adventures.

Usagi's memories are returned by Luna and is upset that Mamoru does not remember her. The part of Mamoru that is his devotion to protect Sailor Moon splits off from him to become a separate entity, the Moonlight Knight, who comes to the aid of Sailor Moon when in need. In their last battle with the Makaiju, the Moonlight Knight is defeated and returns to Mamoru causing his memories to come back.

At the beginning of the Black Moon Arc, Mamoru starts having nightmares and visions that if he stays with Usagi she would die. His visions are usually correct, so he was petrified of losing Usagi. Because of this breaks up with her, but stills aids her in battle as Tuxedo Mask. They both become depressed and Usagi even suspected that Chibiusa was the cause of the breakup. They eventually do get back together. It is later revealed that it was his future self that sent the dream to test their bonds.

Children
In the 30th century, as Neo Queen Serenity and King Endymion, they bear a child named Princess Usagi Small Lady Serenity, nicknamed Chibiusa. Usagi first realized a child would be born soon after sensing a heavenly body being born inside her. Chibiusa looks similar to her mother, having pink hair styled in rabbit ear-shaped buns. In Parallel Sailor Moon, Chibiusa is in her third year of middle school.

Also in Parallel Sailor Moon, Usagi and Mamoru have a second child, Ko-usagi Tsukino. Ko-usagi also has pink hair like Chibiusa, and wears her hair in double-rabbit ear buns.

Fanon
It is among the most popular shippings. The relationship between Usagi and Mamoru was a major plot point for the series causing there to be many fans. Other fans of the show do not ship them as they feel that the present-day Usagi and Mamoru's feelings for each other are merely a result of their past lives' love and not their current lives. However, this is not the case. They fell in love with one another because their personalities were the same as in their past lives. Furthermore, Usagi and Mamoru developed an unspoken attraction to one another in the beginning of Sailor Moon. They both demonstrated many symptoms of a crush on one another and eventually realized they meant a lot to one another before they knew about their past lives.

Given the great popularity of the franchise in yuri shipping and the status of this ship as the center of biggest part of het shipping in it, this ship and Mamoru in particular are notorious as targets of several het vs slash ship wars. Although this is mostly common in modern Western fandom, the earliest nods to it were made by the first director of the show during the premiere broadcast of the original anime, when he joked that he wanted to kill Mamoru, or at least reduce his screen time with Usagi x Rei shipping.

The MamoUsa ship is commonly pitted against the SeiUsa ship.
