Additional Comments:

Kerberos is the Beast of the Seal, one of the guardians of the Clow, and Kero's job is to watch over the Clow Cards. However, Kero fell asleep, and Sakura opened the Clow and accidentally scattered all the cards. Kero stays in a stuffed animal shape for most of the first and second series, because Kero cannot change into Kerberos' original shape without enough magic. Sakura has to capture the Firey and the Earthy cards before Kero can transform into Kerberos' true form.

In Greek mythology, Cerberus, or Kerberos, is a three-headed dog with a serpent or dragon tail, which guards the entrance to the Underworld.
