The Chadwick Family is Rikki's family. They are not very close, but do love each other, and consist of Rikki and her father; it’s implied her dad has a girlfriend (in H2O: Mermaid Adventures this is stated as canon) and it is unknown what happened to her mother beyond the fact that she divorced her father.
Terry Chadwick[]
Terry Chadwick is Rikki's father. His profession is unknown, but he does mechanics with his motorcycle.
Rikki Chadwick[]
Rikki Chadwick is one of the main protagonists of the series. She is a 16 year old rebellious schoolgirl who became a mermaid.
The Chadwick Family Home[]
The Chadwick house is Rikki's Home. It’s rather small, and she used to lie about it in order to appease her boyfriend, Zane Bennett, who is richer than she is, but she eventually told him the truth.
