In the anime, Chibiusa changes into her princess form when she needs more power than her Guardian or civilian forms allow, similar to how her parents can become Prince Endymion and Princess Serenity when they need more power. In this form, she wears a dress and jewelry identical to that of Princess Serenity, albeit smaller. This happens twice, during the final battles of the second and fourth series. Like her mother, Chibiusa grows a pair of functioning, angelic wings during the SuperS climax. She does this after Usagi, as Serenity, grabs her while they are falling, and the two of them collide with Pegasus. It is unknown if she grew the wings on her own or with Usagi's or Pegasus' help. The Chibiusa of the future, Small Lady, is also shown in her princess dress when she is not transformed, so this form is not exclusive to power-ups.
