Editing Sailor Moon (character) (section)

===Variations===
Usagi's character is different between versions of the series. In the manga, she starts out as a crybaby, but quickly matures and embraces the responsibilities of her role.<ref name="vol1">{{cite book|last1=Takeuchi|first1=Naoko|title=Pretty Soldier Sailor Moon Vol. 1|date=1996|publisher=[[Kodansha|Kodansha Comics]]|location=Tokyo|isbn=4061787217}}</ref><ref name="act52">{{cite book|last1=Naoko|first1=Takeuchi|title=Pretty Soldier Sailor Moon Vol. 18.|date=1997|publisher=[[Kodansha|Kōdansha]]|location=Tōkyō|isbn=4061788582}}</ref> Regardless of her maturity as a heroine, the manga often portrays Usagi as lazy or unmotivated in applying herself in her civilian life, such as making fun of her tendency to use [[kana|phonetic writing]] instead of more [[kanji|formal script]] or consistently receiving low academic marks.

The [[Sailor Moon (anime)|original anime]] often portrays Usagi as being more childish.<ref>{{Cite web |last=D'Alimonte |first=Michael |date=2017-09-12 |title=15 Things You Never Knew About Sailor Moon (The Character) |url=https://screenrant.com/sailor-moon-serena-usagi-facts-trivia/ |access-date=2023-12-25 |website=ScreenRant |language=en |archive-date=May 9, 2022 |archive-url=https://web.archive.org/web/20220509105146/https://screenrant.com/sailor-moon-serena-usagi-facts-trivia/ |url-status=live }}</ref> She frequently engages in petty squabbles with her friends, usually with [[Sailor Mars|Rei]], and Chibiusa to the point of developing a friendly rivalry with them or sometimes her little brother Shingo with whom Usagi isn’t shown getting along and shares a sibling rivalry with. Though she is likewise depicted as deeply caring of those around her, and even of her enemies. Repeated themes in the series depict Usagi feeling sympathy for villains she encounters, and working to help redeem them. Her clumsiness and other slovenly aspects are often highlighted for comedy purposes, both as a civilian and while fighting her enemies. Characters often comment on the unlikeliness of someone with as many graceless qualities like Usagi being a fierce warrior like Sailor Moon, but her lack of grace is simultaneously described as charming to those around her. Usagi's gregarious personality is often emphasized as bringing people together, including her friends and allies.

In the live-action series, Usagi differs slightly from her manga and anime counterparts. She is more outgoing and extroverted, and makes friends very easily. This immediately puts her personality in conflict with the other Sailor Guardians, each of whom is solitary to some degree. She rarely uses [[Honorific speech in Japanese|formal speech]] with those of her age (though she does with adults), and refers to everyone as "''given name''-chan" (which is very informal and a way of expressing closeness). She teases Ami when Ami continues calling her "Tsukino-san" (a formal way of speaking to classmates), saying that it is like they are not friends.<ref>''Pretty Guardian Sailor Moon'', Act 5.</ref> Every time a new Sailor Guardian appears, Usagi immediately tries to befriend them, even though almost all of them resist. However, Usagi eventually makes the other Sailor Guardians realize that they are stronger together than alone. Usagi also has a habit of forcing her interests on her new friends. This is prominent in her relationship with Rei, where Usagi repeatedly tries to get Rei to sing.{{Citation needed|date=April 2016}}
