To protect herself, Sailor Mercury in the live-action series possessed the ability to generate a sword from standing water, which did not feature in the anime or manga. She obtained the ability to emit a stream of bubbles after awakening her Senshi power in Act 29, and she used this talent twice throughout the series. She also possesses the ability to control the weather but does not use this power until late in the series.
In the final episode, it is revealed that Sailor Mercury has become immortal due to a deal made with Tonia Zaroff, the woman who murdered her family. Now that she cannot die, she uses her power on a daily basis to protect others by sending out messages through her fan club. She also makes an appearance in the final scene of the series watching over her friends as they graduate from high school.
Sailor Mercury was created by manga artist Naoko Takeuchi. The original story was going to be about a girl who lost her memory because of an accident and then finds out that she is a famous singer who must fight against evil forces to save mankind. But since the manga's release in 1981, many changes have been made. For example, there are now seven Senshi instead of six, and their powers and personalities have also been altered somewhat.
Takeuchi based Sailor Mercury on the character "Mary Marvel" from issue #8 of DC Comics' anthology series Adventure Comics.
Sailor Cosmos is reported to have the Lambda power, which she retains even as Eternal Sailor Moon. It is stated as having the ability to lose everything in order to save everything. This can be construed in a variety of ways. One interpretation is that it means that her power can destroy anything at any time, but this would make her an invincible monster who could not be defeated. A more reasonable interpretation is that it simply means that she has the capacity for such great strength that nothing can stop her from saving everyone.
In addition, her moonstone bracelet acts as a magnifying glass when needed. It is possible that this is what allows her to control her powers at all times. However, it is also possible that it amplifies the danger of using them improperly or against a villainous opponent. For example, if Sailor Cosmos used her power to destroy something vital to Princess Serenity's body, then there would be no saving her. Also, since Sailor Cosmos' power seems to come from the moon, it may be that its use requires a lot of energy. If she uses it too much, then she may become weak or even die.
Finally, it should be noted that even though Eternity Moon reports that Sailor Cosmos has the Lambda power, she still needs sleep and food.
Ami, Usagi's sister, is the first person in Usagi's world to be exposed as a Sailor Senshi, and she is unquestionably an important part of the group. Her knowledge and ability to think on the go aid the squad in dealing with formidable foes. Sailor Mercury, on the other hand, is not a very physically imposing member of the Sailor Senshi. But she is brilliant at using her brain instead of her fists to fight crime.
Sailor Venus also has skills that go beyond just dressing up in a cute outfit, but it's her relationship with Sailor Mercury that forms the core of the team. They work well together because they have similar abilities and know how to use them effectively. Also, Sailor Venus' beauty is such that people often don't notice her when she's fighting off enemies. This allows her to perform amazing feats of agility while still maintaining her composure.
Sailor Mars, the martial artist of the group, is the strongest of the Sailors Senshi. She is also the most aggressive and does not hesitate to use physical force when necessary. But even she admits that Ami is far more skilled than she is, noting that "even I can't fight like my sister".
Finally, there's Luna, the psychic of the group. Her role on the team is mainly limited to psyching out opponents before fights involving monsters or aliens. But she does have one powerful spell known as the Silver Crystal Ball that can destroy entire planets!
Sailor Jupiter is the most physically powerful of the Inner Solar System's Sailor Scouts, capable of picking up and slamming a Youma to the ground before even transforming into her Scout form. She is also a martial artist and the Inner Scout team's hand-to-hand combatant. As a child, she traveled the world with her scientist father, who was researching new energy sources for Earth's civilization. When their work brought them to near-extinction, they were rescued by Queen Beryl who adopted Jupiter as her own daughter. Ever since then, Jupiter has wanted to help others in need, becoming a Sailor Scout.
In addition to being strong, Jupiter is wise beyond her years and tends to get her friends out of trouble with her fighting skills. She is also a talented musician who can play the piano and violin. As a child, she used her powers to aid in saving people during earthquakes and other natural disasters.
When she isn't working on developing human technology, Jupiter spends her time sailing around the world in her spaceship, the Jupiter Star. It is here that she trains with Doctor Atria to improve her combat abilities and craft new tools for use in warfare. In addition to having her own deck, the ship features a holographic projector that allows Jupiter to appear anywhere on board as long as there is enough light to see by. The Jupiter Star is also equipped with an artificial sun that provides constant heat and light regardless of where it travels to.
