Chibiusa was bratty, slightly spoiled, and often got into fights with Usagi, even over the simplest things. She was attached to her future father, Mamoru, and even after the R season (relating to the manga), she still argued with Usagi over Mamoru, though it was unknown, if she was still attached or did it to bother Usagi. She also heavily criticized Usagi, like Rei, calling her a crybaby and clumsy.
