From the talented  Roy_Wolverine of a wonderful pic that I commissioned him

Here we see Maku meeting with Kai again near the village of Mata Nui during his family visit to the Polynesian mer kingdom. Kai is very grateful to the prince as he was the one that saved and turn her into a merotteress. While on the surface, she respect the ocean and has wish to be apart of it. Now she is more than being one with the ocean, but get to be in a world she felt truly belong to and to see the merwolf prince again; she can't be more happier than to thank him for giving her a new beginning.
