Everything about Kero, The Protector of the Clow Cards!

Keroberos or Kero is the guardian of the Clow Cards and has an affinity for the Sun. Kero derives his strength from the sun, unlike Yue who derives his power from the moon, and his master for sustenance.

Most fans would remember the iconic scene of Kero and Sakura in Cardcaptor Sakura, where they first met. Keroberos was sealed in the book along with the Clow cards by Clow Reed. When Sakura opened the book, the seal got broken and released the Clow cards and Keroberos.

Kero has taken a liking towards Sakura and chose her as the candidate to become the owner of the Clow Cards. The journey of Sakura to pursue the Clow cards was together with the guardian Keroberos or Kero. Kero’s true form remained hidden till Sakura was able to capture all the main elementary cards.

Kero’s most powers were sealed, and he was shown as a plushie in the series. Keroberos regained his power when Sakura captured the last element card Earth and sealed it.

Kero gained his true form along with his fire powers. Throughout the series, Kero was the source of comedic relief and his dislike towards Syaoran and fear of Touya were evident.

Kero had to remain hidden from Sakura’s family, especially his brother Touya, who also has magical powers.

Keroberos, for the most part, has remained hidden and acted as a plushie in front of Touya. He’s unaware that Touya is aware of Kero and his presence, and he can tell that Kero is not just a simple toy.

Kero is quite protective of Sakura and doesn’t tolerate Syaoran’s initial hostile behavior and how rudely he treated Sakura.
