Movie
Description
Chibi Chibi is a fictional character from the fifth and final story arc of Pretty Guardian Sailor Moon Cosmos the Movie, serving as a mysterious and crucial figure in the confrontation with Sailor Galaxia. The character appears as a very young girl with an estimated apparent age of about two years old. She has large blue eyes and dark pink hair styled into two distinctive heart-shaped odango with small ringlets framing her face, a design that closely mirrors elements of the protagonist's own iconic hairstyle. Her vocabulary is extremely limited; she typically only repeats simple words she hears from others or utters her own name, Chibi Chibi, which has become her identifier. Despite her childish demeanor, her arrival is unusual: she floats down to Earth using an umbrella as a parachute and soon integrates herself into the household of Usagi Tsukino, the protagonist, by using a hypnotic power that makes the family believe she has always lived there, though the Sailor Guardians themselves remain immune to this effect.

The true background of Chibi Chibi diverges significantly from the original 1990s anime adaptation, and the film follows the canon established in the original manga. In Pretty Guardian Sailor Moon Cosmos the Movie, Chibi Chibi is not a separate being but a disguised form of Sailor Cosmos, who is the ultimate future incarnation of Sailor Moon herself. Sailor Cosmos hails from a distant and bleak future where an endless war against Chaos, known as Sailor Chaos, has decimated the galaxy and the Sailor Guardians. Overcome by despair and regret after years of futile battle, Sailor Cosmos chose to flee from her own time. She transformed into the persona of Chibi Chibi and traveled back to the past to secretly guide her younger self, Eternal Sailor Moon, during the final battle against Sailor Galaxia and the entity Chaos. Her primary motivation is born from a wish to change history. She originally wanted to persuade Eternal Sailor Moon to destroy the Galaxy Cauldron, the birthplace of all stars and Sailor Crystals, believing that this was the only way to permanently eradicate Chaos and prevent the tragic future she had experienced.

In the unfolding narrative of the film, Chibi Chibi acts as a silent guardian and a source of power. She carries a golden censer or incense burner, which is revealed to be the vessel that protects the spirit of Princess Kakyuu, the ruler of the Sailor Starlights' home world. As the story progresses and the Sailor Guardians face overwhelming odds, Chibi Chibi demonstrates the ability to transform into her Sailor Guardian form, known as Sailor Chibi Chibi Moon. In this form, she wears a miniature version of Eternal Sailor Moon's uniform, colored in red and blue and complete with a pair of wings in the manga and film continuity, and wields a small heart-shaped scepter. She does not typically engage in direct combat with powerful attacks; her primary function is to amplify the power of Eternal Sailor Moon. Through her presence, she transforms Sailor Moon's ultimate attack from Starlight Honeymoon Therapy Kiss into the far more powerful Silver Moon Crystal Power Kiss, providing the necessary strength to confront Galaxia.

The most significant relationship Chibi Chibi holds is with Usagi Tsukino, as she is in fact a future version of Usagi herself. Her disguise allows her to stay close to her past self, offering comfort and support during a time of intense suffering and doubt. This creates a profound but silent bond, as Chibi Chibi observes the battles while hiding her true identity. Her development culminates in the film's climax when her true form is finally revealed as Sailor Cosmos. At this critical moment, she expresses her original wish for Sailor Moon to destroy the Galaxy Cauldron. However, by witnessing Sailor Moons unwavering resolve to protect the Cauldron and all the lives it represents, choosing instead to sacrifice herself to purify it, Sailor Cosmos finds the courage and hope she had lost. Inspired by her past selfs decision, she rejects her earlier despair and returns to her own future time, ready to continue the fight against Chaos with a renewed spirit, implying that she will now follow the path of sacrifice and purification rather than destruction.

Chibi Chibis notable abilities are diverse and function on both a physical and metaphysical level. She possesses powerful teleportation capabilities, able to move herself and the other Sailor Guardians across vast distances, such as into the heart of Galaxias stronghold. She can generate strong defensive force fields and share energy or transfer knowledge simply through physical touch, as demonstrated when she empowers Sailor Moon or communicates with Chibi Moon. In her Sailor Chibi Chibi Moon form, she utilizes her heart-shaped scepter for defense. Her most unique power, however, is her ability to manifest the Seal Sword, a weapon intended to seal away Sailor Galaxia. As Sailor Cosmos, her true potential is hinted to be immeasurable; she possesses the Cosmos Crystal, also known as the Lambda Power, which is described as the ultimate ability to harness all the Sailor Crystals in the galaxy, representing the final and most powerful evolution of a Sailor Guardian.
