Mokona is a mischievous, nonsensical rabbit-like creature with a striking similarity to a white manju bun, with a red gem in his forehead above his eyes. From this gem he can produce a tent for the girls to sleep in, food, and other necessary supplies. He is unable to speak, aside from repeating the sound "puu", although Hikaru seems to be somewhat able to understand him. In the manga, Mokona is revealed to be the Creator of the Earth, Cephiro and the other planets, as well as the laws for each planet. In the ending of the second series, Mokona and the rest of the Mashin announce that they will be traveling to other dimensions.

In xxxholic and Tsubasa: Reservoir Chronicles
Mokona of Cephiro is a separate character from Mokona Modoki from ×××HOLiC and Tsubasa: RESERVoir CHRoNiCLE. It is revealed that Yuko Ichihara and Clow Reed met the original Mokona of Cephiro during the creation of Cephiro, and that they learned of the existence of alternate realities because of Mokona. After this meeting, Yuko and Clow would go on to create the two Mokona Modokis based on the original Mokona. Several differences between the Mokona Modokis and Mokona of Cephiro include:
- The two Mokona Modoki are smaller, with longer ears
- One of them is black whilst the other is white (like the original)

- Both Mokona Modoki have 'secret techniques'.
