Precure Diamond Power (パワープリキュアダイヤモンド! Purikyua daiyamondo Pawā!?) is the official transformation phrase used by the Cures in Diamond Precure. To activate their transformation, the girls need their Diamond Brooch and their Mascot Pety.

Precure and their Mascot

Kokoro (Pety)

Miya (Pety)

Kira (Pety)

Takara (Pety)


Pety gets up then shouts "Hearts Precure! Let's go" And there she sends Diamond Brooch to the heart of Precure then by turning they shouts "Precure Diamond Power" Then of the brooch take out pink ribbons (kokoro) Yellow Blue (Miya) (Kira Vert) (Takara) which wrap all their body. Then Pety sends small pink hearts to the dress of Kokoro, to the shoes of Miya and to Kira's palms and Takara's hair. Every time a heart affects the body this part forms. Precures open their eyes and begin their introductions
