JunJun

ジュンジュン

JunJun (her name remains unchanged in the dub) is the green-haired tomboy of the Quartet. She is athletic and somewhat impulsive. JunJun works as an acrobat in the Circus, where she is known as the Magician of Acrobatic Feats. Her Senshi counterpart is Sailor Jupiter, and her associated color is green.
Naoko Takeuchi described her as vulgar and a Yankee, noting that she uses very informal male speech. She is also said to have dark skin and to be the third sister, a detail that corresponds to the number and size of her asteroid. She was originally intended to ride a motorcycle. In the manga, it is revealed that she is actually Sailor Juno, named after the asteroid Juno and the Roman goddess Juno.
In the anime, she often speaks with a hard edge. She tends to wear biker outfits outside of her circus uniform, even though she is never shown riding a motorbike. She likes to let her targets attain their dreams before she takes their dream mirrors, which may be an oddball reference to the mothering aspect of the goddess Juno. She always summons male lemures; she is the only member of the Quartet to do so.
