cerberus is the guardian beast of the clow. his symbol is the sun. he first appeared when sakura came across the clow book. it was his duty to watch over the clow cards and not let them escape...but, he fell asleep. ^^ in appearance, he looks like a teddy bear with wings. (or, according to mako, he looks like a mouse. ^^) this is because there was not enough magic to sustain his true appearance. in actuality, he looks like an armoured lion...with wings. ^^ He first appears in his true state when sakura captured "the earthy" and "the firey." it was "the firey" that was the key to allowing him to go back to his true form. (this was quite an amusing moment because sakura who saw cerberus transform, had no idea it was him. the result was cerberus promptly crashing into the ground. ^^ this is another example of the few times that sakura is clueless. ^^) kero-chan is very cute and his personality matches with it. you can often see him playing video games, watching tv and he has this liking of sweets. it's like the most important thing in his life...other than video games. ^^

counterpart: kero-chan's counterpart is spinel, a kawaii black cat with butterfly wings and somewhat evil looking eyes. he is somewhat a foil to Kero-chan because he likes to spend most of his time reading. books and video games...they don't get any more different than that.
