King Neptune is the ruler of the entire ocean. Everyone fears him greatly. He has powers that can zap anyone, destroy anything, transform one thing into another, etc. He has a different look in the movie, probably because that is an older version of him. Neptune has two children, Prince Triton and Princess Mindy, and a wife named Queen Amphitrite. To him, being the king of the sea is nothing more than the love for his family. He is voiced by John O'Hurley.
