JunJun, whose name remains unchanged in the dub, is the green-haired tomboy of the Quartet. Athletic and somewhat impulsive, she is an acrobat in the Circus, known as the Magician of Acrobatic Feats. Her Senshi counterpart is Sailor Jupiter, and her color is green.
Naoko Takeuchi described her as vulgar, a Yankee, and noted that she uses very informal male speech. She has dark skin and is the third sister, corresponding to the number and size of her asteroid. Originally, she was supposed to ride a motorcycle. In the manga, it is revealed that she is really Sailor Juno, named after the asteroid Juno and the Roman goddess.
In the anime, JunJun often speaks with a hard edge. She tends to dress in biker outfits even when not in her circus uniform, though she is never shown riding a motorbike. Interestingly, she allows her targets to achieve their dreams before taking their dream mirrors, which might be a nod to the nurturing aspect of the goddess Juno. She is the only one of the Quartet who summons male lemures.
