One of the Dragonets of Prophecy, Tsunami is brave, very bossy and especially protective of her friends. As a Seawing, she has glow in the dark scales and is a very good fighter. However, she didn't grow up understanding the hidden meanings of her glowing scales, and didn't learn to communicate with them until later in life.

Tsunami was born under a mountain in the Claws of the Clouds Mountain Range as the SeaWing needed for the Dragonet Prophecy. They eventually escaped, and wound up in the Skywing Kingdom as prisoners forced to fight in the arena.

After escaping the arena, they ended up reaching the Seawing Palace. It was here that Tsunami met her mother, Queen Coral and discovered that she was royalty. She also met her younger sister, Princess Anemone, and Animus. She solved the mystery of why all of Queen Coral’s heirs were dying in their eggs, and saves her new baby sister, Auklet, in the process.

After the prophecy is fulfilled, she helps start Jade Mountain Academy, where she is the Headmistress.
