Cleo can be described as shy, awkward, patient, trusting, gullible and a loyal friend. Her loyalty is her most prominent feature. In fact, she is so loyal that it can make her easily manipulated at times as she sees the good in people first and foremost and refuses to see the bad. Her mermaid power allows her to mold water into a different shape, and from the second season, to create a strong wind that can reach up to 200 km/h. Cleo appears in all 3 seasons.
