Sailor Moon Seasons:
Sailor Moon
This is the dub version of the first season. If you find a neat little symbol in the description, go to the bottom and check out the footnotes, which explain parts of the original version that were changed/left out of the dub version.
Serena wakes up, screaming. She's woken up too late for school, again. Serena quickly runs down the stairs, runs out the door after almost forgeting her lunch, and heads for school, yawning. On the way she notices several kids poking a black cat. Serena chases off the kids, feeling sorry for the cat, and then notices two bandaids on its forehead. She wonders if the cat's hurt, and pulls them off.
Under the bandaids is a crescent moon. The cat looks up at her, and then does a somersault off her head and lands on a nearby car, and stares at Serena. Serena gets a little freaked out, then hears the bell for school and runs off. The cat stares after her.
In another dimension, Queen Beryl says that the time it was time to find the silver imperium crystal, but had to gather energy before doing this. She summons Jedeite, and tells him to gather the energy from humans.
Serena got a 30 on her test. She feels terrible, and doesn't want to go home. Her friend, Molly, got an 85, and she was a little disappointed, since Melvin had gotten a 95 and beaten her. He says he didn't study, so he didn't get a perfect score, and Serena and Molly both got sweat drops. Serena says she didn't want to go home because her mother would find out and not let her get the new Sailor V game. Molly says she should come to her Mother's jewelry store to cheer up, since her Mom was having a big sale. Serena happily agrees to go.
Serena goes there, but the store is too packed for her to buy anything. Molly notices that her mother is acting a little weird, and Serena apologizes to her but says she has to go home. Serena slowly walks home, then gets frustrated, crumples up her test, and throws it behind her. It hits a guy in the head, who yells at her and calls her "Meatball Head." Then he sees the 30 on her test and tells her to study harder. Serena snatches the test back and yells at him, and then walks off.
Her mother goes nuts about the test, and then throws her out of the house. Eventually, Serena's mother let her back in, and Serena goes up to her room to go to take a nap. Then the cat from before enters her room from the window and walks onto her bed. Serena notices the cat, but all of a sudden the cat started talking to her! Serena starts getting really scared as the cat introduces herself as Luna, and tells her she is the "Sailor Scout of the Moon." She also tells her that Serena has to protect the princess of the Moon when she is found. Serena doesn't believe her at all, but Luna does a back flip and somehow creates a special brooch for her. Serena is very happy for the brooch, and puts it on the bow of her school uniform. Luna tells her to say, "Moon Prism Power." Serena repeats it, and then transforms into Sailor Moon.
Serena, now Sailor Moon, is shocked at her new outfit, but Luna tells her that she has to help her friend Molly. Sailor Moon hears Molly's cries, and heads out to her mother's jewelry store. Meanwhile, a monster disguised as Molly's Mom and sent by Jedeite has been sucking energy from all the customers by the jewelry that she sold them. When Molly realizes her mother is acting weird, the monster starts choking her. Then Sailor Moon arrives, saying she was going to punish her for hurting Molly. The monster starts attacking her, and all Sailor Moon does is run away. Then someone threw a rose, tells Sailor Moon not to give up, and introduces himself as Tuxedo Mask. Sailor Moon starts crying anyways, and Luna tells her to throw her tiara at her and say "Moon Tiara Magic." Sailor Moon tries it, as her first attack, and the monster is destroyed. Tuxedo Mask leaves, and Sailor Moon exclaims what a hunky guy he was.
This continues for a while, with Jedeite sending out monsters to collect energy, but Sailor Moon destroying them before Jedeite can recover the energy, and Tuxedo Mask helping out when she's in bad trouble. Sailor Moon also finds two more Sailors, Sailor Mercury and Sailor Mars. Sailor Mercury appears as Amy, the lonely girl who was transferred from a very smart private school. Everyone is a little mean to her because she's so smart and coming from a great school, but Serena treats her the same as anyone and they became friends. Mercury's powers are associated with water, and her attack is "Mercury Bubbles Blast!" Sailor Mars appears as Raye, the priestess of the Cherry Hill temple with a big temper. Serena and Raye definetly do not get along with each other, and fight constantly. Mars' powers are associated with fire, and her attack is "Mars Fire Ignite!" She also can create an anti-evil scroll, which when placed on a monster can freeze them in place. However, this power comes from her abilities as a priestess, and not a Sailor. Meanwhile, Serena finds out that her crush, Andrew, is friends with the guy Darien, who was the one that called her "Meatball Head" earlier. He encounters them several times, and while Raye thinks he's cute, Serena thinks he's a "big dork."
Finally the showdown came between the Sailors and Jedeite. Queen Beryl is very angry at him for failing to collect energy, and Jedeite has one last chance to get back in her favor, which is to kill the Sailor Scouts. He sets up a trap by threatening to destroy Tokyo, and gets the Sailors to meet him at an airport. They transform at the airport, revealing their identities to him by mistake. Then he uses his powers to control airplanes so that they run the girls over. Meanwhile, Tuxedo Mask appears and starts fighting Jedeite with his cane, but Jedeite knocks him into the bay. Sailor Mars is about to destroy a plane with her attack, but Luna tells her that she'd have to pay for that airplane for the rest of her life. They run away, seeing no alternative, and then Sailor Mercury uses her attack to fog the area, and Sailor Moon gets the planes to chase her over to Jedeite. Sailor Mars uses her anti-evil scroll to freeze Jedeite in place, and he almost gets run over by the planes. He transports himself to Queen Beryl's dimension in just enough time, but Queen Beryl is so angry at him that she freezes him in a stone, telling him to "sleep FOREVER!"
The girls think Tuxedo Mask was dead, and were all very sad. Then he appears to them, assures them that he's fine, and then flies away into the night. Sailor Moon is all heart-eyed again, and Sailor Mars is a little too.
Queen Beryl speaks to a new general, Nephlyte, who assures her that he will do a better job then Jedeite. Nephlyte explains that he would take energy from one specific person as they reach their maximum energy peak, which was a better way then getting energy from a large group of people. Nephlyte does this by placing a certain Japanese symbol on a belonging of the person, which causes them to use a lot of energy related to that belonging. For example, a photographer starts going nuts taking lots of pictures with the symbol on his camera, or a sewing teacher creates a wedding dress from fabric with the Japanese symbol on it. A monster appears from the object with the symbol to take the person's energy, and possibly take energy from people around this person. However, each time this happened, the Sailors appear, and use their attacks to destroy the monster. Nephlyte attemps to find out Sailor Moon's identity when she becomes a major nuisance, but instead stumbles upon her best friend, Molly.
Molly encounters Nephlyte several times, and develops a crush on him, or his human identity (Maxfield Stanton). The girls find out that Maxfield Stanton is in fact Nephlyte, and Serena is really worried about this crush that Molly has. Meanwhile, Nephlyte decides to start looking for the silver imperium crystal, since he's failed in gathering energy. Zoisite *, another general, shows up, and tries to stop him from looking for the crystal, claiming it was her job. Malachite, another general (that Zoisite's in love with), tells her to wait and see if Nephlyte finds the crystal, and then take it from him. Nephlyte creates a black crystal which will react to the silver crystal, and the crystal detects Molly. He thinks that Molly must have the crystal, but instead he finds that his crystal was reacting to her love for him.
Nephlyte's been discovering this by breaking into Molly's house while she was sleeping. When Molly wakes up, Nephlyte thinks that perhaps she knows who Sailor Moon is, and tells her all about himself, and who he's lied to her from the start. Molly is very sad, and when Nephlyte leaves, she calls up Serena and tells her. Nephlyte hears the name Serena, and decides to check it out. Meanwhile, Zoisite finds out about this black crystal, and decides to steal it in order to find the silver imperium crystal. While Zoisite kidnaps Molly to use as black mail, Serena is running to Molly's apartment to help out. Then the road starts shaking and twirling, and Serena transforms to Sailor Moon. Nephlyte laughs, saying he's discovered her identity, and was about to attack her. Then Tuxedo Mask appears and stops him, and Nephlyte leaves. Sailor Moon is all worried that he knows her identity, but Tuxedo Mask says that he has bigger things on his mind.
Nephlyte goes to where Molly is being held hostage by 3 monsters, and easily rescues her. He carries her to a park, and Molly bandages his arm with a part of her nightgown. She says that she'd always wanted to go to a restaurant with him and eat choclate parfaits, and Nephlyte agrees to go someday. Then the monsters appear, and strike him with a huge root-like stick. Nephlyte is badly hurt and the roots keep sucking energy from him, and then Zoisite appears and takes the black crystal from him, gloats, and leaves. Molly tries to pull the roots out, and the monsters laugh and say she'll never do it, but she pulls it out a little and surprises them all. Then the monsters strike her away from him. Then the Sailors appear and destroy the monsters, but Nephlyte is too badly hurt to survive. Molly starts crying, and Nephlyte says that he's sorry he couldn't go and eat chocolate parfaits after all, and that every since he'd known her he'd lied to her. Then Nephlyte dies, and dissolves into bubbles that float into the sky. The only thing that was left was the bandage that Molly had used. Molly keeps on crying. :'(
The NegaVerse ^ tells Beryl that they'd gathered enough energy to find the silver imperium crystal. Then Queen Beryl tells Zoisite that in order to get the silver imperium crystal, she has to collect the 7 Rainbow Crystals. Beryl explains that her 7 Shadow Warriors had been her finest warriors, and had fought the war with Queen Serenity. But then the silver imperium crystal had shattered into the Rainbow Crystals, with a Shadow Warrior locked into each piece. They disappeared into earth's atmosphere and were reborn into humans. Beryl had been very sad to lose them, and wanted to get them back as well as the Rainbow Crystals. Zoisite asks how to find the humans with the Shadow Warriors locked in them, and Queen Beryl creates a crystal to find them.
The next Sailor has joined the team: Sailor Jupiter. She was transferred from her old school and everyone at Serena's school is scared of her, but Serena is nice to her and treats her the same. Lita is very surprised, but offers her some food that Serena gladly accepts and discovers is really delicious. Serena befriends her, and Luna eventually finds out she's Sailor Jupiter. Jupiter's powers are associated with thunder, and her attack is "Juptier Thunder Crash!" or "Jupiter Thunder Bolts Crash!"
When Zoisite finds a human with a Shadow Warrior in them, she uses the dark crystal to open the person up and take the Rainbow Crystal away from them. Then the person turns into the Shadow Warrior that once inhabited them. At that same time, Luna creates a Crescent Wand for Sailor Moon, that allows her to change back the Shadow Warrior to the human they use to be. After Zoisite takes away the Rainbow Crystal, usually a fight happens between Tuxedo Mask, the Sailors, and Zoisite. During this time, Tuxedo Mask dropped his Crescent Moon Locket, and Sailor Moon picked it up. When she tries to return it to him, he tells her to keep it for the time being. After all the Shadow Warriors are unlocked and defeated, Tuxedo Mask has 2 crystals, the Sailors have 1 crystal, and Zoisite has 4. Zoisite goes after the Sailor's crystal, by using Molly as a hostage, and gets the crystal from them.
Zoisite turns to Tuxedo Mask's crystals by teaming up with Malachite, creating a fake Sailor Moon that she disguises herself as. The Sailors follow the fake Sailor Moon and are captured in a dome by Malachite, while Tuxedo Mask saves the fake Sailor Moon, who looks like she's in danger. Then Zoisite strikes Tuxedo Mask and reveals herself, and starts battling with him. In the battle, Tuxedo Mask's mask falls off, revealing Darien to Queen Beryl (who's watching in her crystal ball). Zoisite almost defeats him, when an attack comes out of nowhere called "Venus Crescent Beam smash!" which hurts Zoisite and allows Tuxedo Mask to escape.
Meanwhile, Malachite is shrinking the dome that's captured the Sailors, and they start to get hurt. Zoisite tells Tuxedo Mask to come out and give her the crystals or she and Malachite would kill the Sailors. Tuxedo Mask is about to give them the crystals, when Sailor Venus appears, and uses her attack on Malachite which makes the dome disappear. Then Artemis appears, and says that the fifth Sailor had appeared, and he was her guardian. All the Sailors face off against Malachite and Zoisite, but then Beryl appears and tells them to return immediately.
Beryl tells them she knows Tuxedo Mask's identity, and instructs them to capture Tuxedo Mask and take him to the NegaVerse. Zoisite contacts Darien in his apartment, and strikes a deal to battle out for all the crystals at Crystal Tower, 5 PM.
Serena is really worried about being late for the Scout meeting, and then spots Darien on the street. She smacks him on the back, saying hi, at the exact spot where he was hurt by Zoisite. He looks hurt, and calls her "Meatball Head." She yells at him and tells him not to call her that anymore, and he agrees and then walks off. Serena can't believe that he was nice to her, and then looks at her hand and sees blood on it. She realizes that Darien must be hurt, and decides to follow him. Darien notices her and wants to know why she's following him, and she says because he's hurt. He tells her to leave her alone, but then Serena follows so close that she and him get caught in a red bubble sent by Zoisite, that flies to the Starlight Tower. Meanwhile, Raye is mad that Serena is so late, and then Mina and Artemis show up. They say they felt weird vibes at the Starlight Temple, and the girls head out to check things out.
Darien and Serena arrive at the tower, but Serena is still unconscious. Darien puts out his crystals, Zoisite puts out hers, and Malachite appears and takes them all. Darien gets angry and throws a rose at him, but it hits Zoisite's face. Zoisite gets angry, and then the room starts collapsing. Serena wakes up to hear Zoisite tell them to go up to the roof, and Serena wonders if Darien was brought there because of her. Instead, she finds it's the other way around. Darien and Serena reach an elevator, which slowly goes up to the roof. During this time, Serena asks him why he wants the Rainbow Crystals, and he says that he wants to know who he is. He says that when he was a child, his parents were killed in a car accident and only he survived. But recently he's been having dreams of a princess waiting for him, and Darien thinks that the princess could tell him who he was. Serena is very surprised, and thinks that maybe he's Tuxedo Mask.
They reach the top, and then Zoisite throws a fire ball down the elevator shaft. Serena realizes she has to transform to protect herself and Darien, and so cries "Moon Prism Power!" right in front of Darien and transforms. Darien can't believe it.
Zoisite starts gloating to herself, when Sailor Moon appears, and gives one of her introductory speeches, declaring that a fireball could never stop her. Zoisite laughs, and says she was after Tuxedo Mask, not her. Sailor Moon says that Tuxedo Mask wasn't there, but Darien says that he was, and transforms to Tuxedo Mask in front of her. Sailor Moon is... shocked. Tuxedo Mask tells Zoisite to keep Sailor Moon out of their fight, but instead Zoisite forms an ice spear behind her and is about to strike her with it. Tuxedo Mask sees it at the last second and jumps in front of it, saving her, but then he collapses. Sailor Moon starts crying, and Tuxedo Mask tells her that she has to get the crystals, and that he's always been on her side and always will be. Sailor Moon begs him not to die, and one of her tears starts to sparkle. The Rainbow Crystals fly away from Malachite and form in the tear, creating the imperium silver crystal. Everyone is shocked as the crystal joins with Sailor Moon's Crescent Moon Wand, and Sailor Venus realizes that Sailor Moon is the Moon Princess they were looking for. Then Sailor Moon transforms to a princess.
Luna, Artemis, Princess Serena, and Tuxedo Mask all get part of their memories back. Princess Serena remembers how Tuxedo Mask was Prince Darien, and that they were going to be married, until Queen Beryl attacked the Moon Kingdom. She gave him her Moon Locket, and he went off to fight, where he never returned. Tuxedo Mask remembers it too, and realizes that he's finally found his Princess. Zoisite gets angry and tries to get the crystal away from Princess Serena, but she uses power from the crystal to blast Zoisite back. Then Princess Serena transforms back to Sailor Moon and collapses. Luna says she must be exhausted.
Malachite appears and rescues Zoisite, and then transports Tuxedo Mask away before they can stop him. Then the girls start to look for a way to escape the place they were in. Mercury says that they are in some strange sort of dimension. While she searches for a way out, Luna and Artemis tell them that they use to be a Princesses of their own planets, but also a part of Princess Serena's court in the time of the Moon Kingdom. Queen Serenity sent them to the future when Queen Beryl had attacked her kingdom, and erased their memories so they would be happy in their new lives. But Queen Serenity sent the cats to awaken the Sailors if Queen Beryl broke out of her dimension and tried to attack them again. Sailor Moon has woken up by now, and starts crying, saying she never wanted to be a princess or Sailor Moon, but just wanted to be a normal teenager. Sailor Mars slaps her, and Sailor Moon yells at her and says that she always hated her, but Mars says that wasn't true, and admitted that Sailor Moon was a better leader then she had thought.
Queen Beryl is angry ~ at Zoisite for trying to kill Tuxedo Mask, and so kills her. Malachite is shocked and very very sad, and Zoisite asks him not to forget her. Then, just as the Sailors have figured out how to get out of the dimension, Malachite attacks them. Jupiter, Venus, Mars, and Mercury try to protect her, but get knocked unconscious. Then Sailor Moon pulls herself together and attacks Malachite with the crystal, seriously hurting him. He escapes.
For the next several episodes, Malachite tries to figure out who Sailor Moon is by trying tricks with monsters. The girls kept falling for the tricks, but could always defeat the monster. Queen Beryl also turned Tuxedo Mask evil, and so he attacks them a lot too and tries to get the crystal away from him. Serena is heart broken, but decides that she has to fight him anyway. She even manages to bring back some of his memories by using her "Moon Healing Activation" power, but Queen Beryl recaptures him and erases those memories too.
Eventually Sailor Venus and Artemis find an entrance to the NegaVerse, and the girls enter it and start searching the place. Malachite intercepts them and almost gets the crystal from Sailor Moon, but then the crystal reacts « and brings them back in time to the Moon Kingdom. A miniature Queen Serenity speaks to Sailor Moon, explaining the events of the Moon Kingdom's downfall. She says that the Moon Kingdom had always been a happy place, and that Princess Serena had been promised to Darien, the prince of Earth. But when Queen Beryl broke out of her dimension and attacked the Moon Kingdom, she killed almost everyone, and tried to get Prince Darien to join her. Prince Darien refused, and Queen Beryl was so angry she killed both Princess Serena and Prince Darien. Queen Serenity felt terrible, and didn't want such a terrible ending for her Moon Kingdom. So she used the last of her power to lock everyone into the silver crystal, and sent them to the future on earth. She also locked Queen Beryl and her soldiers away into a dimension, where she was stuck for a long time. But she instructed Luna and Artemis to awaken the Sailor Scouts in case Queen Beryl broke out of her dimension again. Then she died, having used all he energy.
Meanwhile, Luna and Artemis discover where Queen Beryl will attack the earth from, which is at the North Pole. They are about to run back and tell the Sailors, but Malachite finds them and attacks.
The girls arrive back in the cave where they ended up at, and can't believe the story Queen Serenity told her. Then they hear Luna and Artemis' cries, to see Malachite attacking them. The Sailors are really angry, and Malachite can't believe they're still alive. Then he creates flying sword things and starts throwing them at Sailor Moon, who passes out. The girls combine their powers to protect Sailor Moon, but they get hurt. Then Sailor Moon wakes up and vows to defeat him, and uses a new power, "Cosmic Moon Power," with the crescent wand, and begins sparkling with power. Malachite throws another flying sword at her, but she reflects it back with her wand, and he gets struck with it. He cries out to Zoisite, and then dies. Sailor Moon and the girls vow to destroy Queen Beryl.
The girls gather at Raye's temple, and talk about how they'll defeat Queen Beryl. Then they transform. Luna wonders if the girls are ready for this, and Artemis assures her that Amy, Mina, Lita, and Raye are very ready. Luna mentions Serena, and Artemis says that maybe she'll have a clutz attack and trip Queen Beryl if she fails.
The Sailors gather their powers together and teleport to the North Pole, where Queen Beryl has sent her "Doom and Gloom" girls to attack them. After several battles, Mars, Mercury, Venus, and Jupiter manage to kill the "Doom and Gloom" girls and protect Sailor Moon, but also get captured by the NegaVerse. ¿
Sailor Moon is captured in a red bubble and brought to Queen Beryl's throne room, where she sees Prince Darien kissing Queen Beryl's hand. Beryl orders him to get the crystal and kill Sailor Moon, and then badly hurts her with his sword. ± She tries to reach her Crescent Wand, but is too hurt to reach it. Prince Darien is about to kill her, when she uses her tiara and strikes him in the stomach with it. He falls over, and then starts to get up again with his sword. Sailor Moon begs him to stop, and shows him the Moon Locket she had, reminding him of the times on the Moon Kingdom. He touches the Moon Locket, and all his memories come back.
Queen Beryl is really angry, and so she creates a shard and throws it at them. Prince Darien throws a rose that breaks the shard into pieces and strikes Queen Beryl in the heart. She melts into the ground, saying it wasn't over yet. Prince Darien is hurt by the shards, and says he'll find a way back to her. Then he passes out. §
The NegaVerse energy rejuvinates Queen Beryl, who goes to the North Pole, ready to take over the earth. Then Sailor Moon walks out, saying that Beryl would never rule the universe as long she lived. Queen Beryl strikes black lightning at her, which creates a big pile of ice shards. The ice shards part, to reveal Princess Serena and the Crescent Moon Wand.
Weather is getting worse in Tokyo. Artemis thinks that the Sailors must have lost, and Luna begs Serena to win and not let Queen Beryl win.
Somehow Serena has heard Luna, and raises her Crescent Moon Wand. Queen Beryl creates more of that black lightning, and Princess Serena cries "Cosmic Moon Power!". They both let lose their power at each other. Princess Serena holds up to her power for a while, but then she gets struck by some of the black lightning. She asks for help from the Sailors, who appear at her side and each of the place a hand on the Crescent Moon Wand. They all cry out their powers ("Mercury Power", etc.) and Princess Serena says, "Cosmic Moon Power... IGNITE!" This creates a huge pink sphere of energy that strikes Queen Beryl and disintigrates her. Soon the sphere has covered the entire North Pole, and over this Serena says that they finally have a chance at peace. ²
Serena wakes up screaming. She's late for school again. She grabs her lunch and runs out the door. Artemis says that Queen Beryl has been destroyed, but the girls all lost their memories. Luna thought it was sad that the girls had no memories of their friendships, but Artemis says they'll meet again. During this we see scenes of Serena running to school with Lita running past her, Amy getting a perfect score at school and causing a sweat drop on Serena, Raye sweeping out the steps to the temple, and Mina waiting for a bus and checking her watch.
Luna wonders about Serena and Darien, then we see a scene of Serena at a hospital with Darien in a hospital bed. Serena says she hopes he feels better after the accident he was in, and Darien thanks her and mentions how weird her hair looks. ¤
* Zoisite was actually a man in the original version, which would mean that Zoisite and Malachite... are gay lovers...
^ The NegaVerse in the dub was actually Queen Metallia in the original version, who gave Queen Beryl orders. For some reason the dub never gave this talking entity a name.
~ The dub never really explained why Queen Beryl was so angry. She got angry at Zoisite because she was in love with Prince Darien and therefore was jealous of Princess Serena.
« Actually, Malachite sent them to a "random time," where he said they could end up in prehistoric earth with dinosaurs, or a war in Europe. So it was all a big coincidence that they ended up back in the Moon Kingdom, and not somewhere else.
¿ In the original version, the Sailors sacrifice their lives to protect Sailor Moon and kill the "Doom and Gloom" girls. This was cut from the episode, but also made the ending much much more confusing.
± In the original version, Sailor Moon gets really really hurt by Prince Darien, but the dub only kept the scene where he strikes her with his sword. In fact, she gets strangled and kicked by Prince Darien several times after that.
§ Another confusing part. In the original version, he protects Sailor Moon from the shards, and gets struck by one in the back. Then he says goodbye to her and dies.
² Actually, the scene with the expanding pink bubble was much longer and showed the dead bodies of Sailor Moon, the other girls, and Prince Darien. Over that, Serena talks about all the little things in her life that make her happy (waking up late, failing another test, eating crepes with her friends, seeing a party dress in a store window), and that those are the thing she wants back.
¤ This whole part did not make sense at all. The dub stole that hospital scene from when Sailor Moon turned Prince Darien good, when he thinks that he's alone and then Serena says, "You're not alone. I'm here." In the original version, they do an almost total replay of their first encounter, where she throws her test behind her and it hits him. But this time Molly is with her and says that he could be the guy of her dreams, and Serena says she has to be kidding.
