As we all know, Chibi-usa is Mamoru and Usagi's daughter from the future. In the anime she came in R to try and find the Ginzuishou to save her mother. She thinks that the loss of the future ginzuishou was her fault because it disappeared when she touched it. She's incredibly homesick in the past with only the Luna-P to connect her to her home, and beyound this she's hunted by the Black Moon family, so she's having a really tough time. Of course she eventually finds out the identities of the senshi, and takes them to the future. There Usagi tries to use her ginzuishou to wake Neo-Queen Serenity, but it doesn't work. Chibi-usa runs of and Wiseman captures her, twisting her thoughts and memories and turning her into Black Lady, an older evil version of her. However, Usagi, as Neo-Queen Serenity, and Tuxedo Kamen reawaken her real memories and she goes back to being herself. She finds out she had the ginzuishou all along and she and Usagi manage to destroy Wiseman.
In SailormoonS Chibi-usa comes back to train as a senshi and to make friends. Her powers as a senshi are stupidly weak, and hilarious to watch. On the making friends side she does much better. She quickly manages to make friends with Hotaru after they meet, becoming a bright spot in the other girl's lonely life. Chibi-usa's the main reason Hotaru managed to fight and overcome Mistress Nine.
In SuperS she comes back again. Well, actually she was only gone a few minutes in the last episode of S before coming right back, so coming back isn't the right phrase. Anyways, SuperS is mostly about her dealings with Pegasus, keeping him from the Dead Moon Circus. Their relationship would be romantic, except he's a bloody horse! She barely ever is around him in human form, and she has a crush on him before ever having seen him as a human! He does have a good personality and a nice voice, but still! Anyways, she spends time with him in her dreams, and talking to him in this globe without telling any of the senshi about their relationship, and pretending not to know more about him then they do. In return for her protection he gives her and the other senshi the ability to transform into their Super forms.In Stars she's only around in the first arc. She begins to disappear when Neherenia kidnapped Mamoru. Eventually she does disappear, only to reappear when he's returned,
