Notraiders
The Notraiders (ノットレイダー) are the main antagonists of the series. They originate from the dark and forgotten parts of the universe and are an intergalactic army of space raiders seeking universal dominion by obtaining the power of the Princess Star Color Pens to purge the universe of light. Later, they seek to capture Fuwa and use her as a vessel in Ophiuchus' ritual. Their leading members are based on yokai from Japanese mythology. Their name is derived from the word "Notto", meaning take over (乗っ取る).

Leaders

 * Darknest / Ophiuchus (ダークネスト / へびつかい座)
 * The leader of the Notraiders and the primary antagonist of the series, Ophiuchus is the exiled 13th Star Princess, who became disillusioned with the universe her fellow princesses created when they voted against her to bestow half of their collective power to all life in the form of imagination. This influenced her to turn on them, and they exiled her, but she eventually regained her strength and assumed the identity of Darknest, a snake-armored figure with an Uwabami-like serpent wrapped around her body. She eventually discards her disguise and minions, capturing Fuwa and the Star Princesses to conduct a ritual to unmake the universe and take away its light. After surviving the Star Princesses's gambit to destroy her through Fuwa, Ophiuchus is ultimately defeated by the Pretty Cures and accepts her loss, while vowing to return if things become twisted again.

 * Kappard (カッパード)
 * A kappa-like commander who wields a lightsaber-like dual blade. He originates from a planet that was destroyed as a result of other races exploiting its naïve people, which led to conflict.

While initially seeking to capture Fuwa by any means, he is also a warrior who considers the Pretty Cures as worthy opponents. After being empowered by Darknest, his blade can now take the form of other weapons by absorbing other peoples' imagination. Given a final chance, he confronts Hikaru by using his own imagination to further power up his weapon, but the Cures manage to defeat him, only for Darknest to take him back to the headquarters. During his final battle, he clashes with the Cures until he discovers Darknest's identity as Ophiuchus.
