Main Marina (voiced by Sonja Ball): A mermaid with waist-length golden blonde hair and green tail who is the protagonist of the show. After she saves Prince Justin of Gandor she falls in love with him and wishes to become human. Prince Justin (voiced by Thor Bishopric): Prince of Gandor and Marina's boyfriend. Winnie (voiced by Anik Matern): Marina's seahorse friend and constant companion. Unlike real world seahorses, she has the ability to scream at very high pitches which causes people to pass out. She also has the ability to fly when she is out of water. Bobo (voiced by Carlyle Miller): Marina's tropical fish friend. He often spies on Hedwig and reports back to Marina and the rest of the gang. Ridley (voiced by Arthur Holden): Marina's sea otter friend and Anselm's companion. Unlike real world sea otters, he seems to be able to breathe under water indefinitely. Anselm (voiced by Aron Tager): Prince Justin's tutor and secretly a sorcerer who was once in love with Hedwig in their youth. Chauncey (voiced by Gordon Masten): Prince Justin's short, goofy and loyal page. Antagonists Hedwig the Sea Witch (voiced by Sonja Ball): The sea witch who acts as the main antagonist of the show. She was once a sorceress who was in love with Anselm until her hunger for power forced him to banish her to the sea. She comes up with plot after plot to capture Marina and Justin so she can exchange them for the Amulet of Power which would make her the most powerful person on both land and water and therefore rule the world. Just like a mermaid, she doesn't have legs and her tail resembles that of a moray eel. The power that she uses most often is to release prehensile vines from her long fingernails. Dudley (voiced by Ian Finlay): Hedwig's halfwitted hammerhead shark second-in-command. His role is a lot more prominent than the other henchmen of Hedwig and he serves as the comic relief among the antagonists. Ray: Hedwig's manta ray. He acts as her means of transport and spy. He is heard speaking sometimes but other times he is shown to only be able to mumble (though Hedwig can understand him even then). It's not clear what his name is as Hedwig once calls him Ray and another time she calls him Manta. Hugo: Hedwig's octopus who acts as her strongman. Barracudas
