The Red Bluster

, also known as Red, is a red sea monster on The Sea Beast.

Biography
Sea monster hunter Captain Crow had a 30-year vendetta to capture the Red Bluster. He assumed her to be a raging monster driven by nothing but violence. However, Maisie saw signs that Red was a more nuanced and thoughtful creature than she first appeared. Even though Red didn't think twice about fighting or even killing if needed, she was also a loyal and brave friend who only wanted to be left alone to live in peace.

Throughout The Sea Beast
During The Inevitable's attack on the Red Bluster, Maisie cut the ropes attached to the Red Bluster to save both the crew on the ship and the Red Bluster. When Captain Crow was angry at Maisie for disobeying him and ordered Jacob Holland to bring Maisie to him. When Jacob refused, Captain Crow held them at gun point. Seeing this, the Red Bluster swallowed them whole and brought them to an island.

When Maisie and Jacob were attacked by the Purple Crustacean, the Red Bluster came to their defense and attacked the Purple Crustacean. It ended up leaving them alone.

The attack left a hole in their boat. Jacob was adamant that they would use the boat anyway, but Maisie asked the Red Bluster to transport them. She carried the boat on her back. Later, Maisie helped pull out all the spears that were stuck on the Red Bluster's back.

Seeing Jacob struggle to spear fish, the Red Bluster swam in circles to force the fish to jump out of the water, helping them catch enough fish.

When Maisie, Jacob and Blue arrived at Rum Pepper Island, Jacob vowed to never hunt sea monsters again. Shortly afterwards, Red noticed that The Imperator ship was on the other side of the mountain and charged towards them, attacking the boat. Maisie and Jacob tried to stop Red, but Red charged anyway, only stopping after Jacob Holland shot her with a spear. Red became angry and wanted to attack Jacob and Maisie. A gunshot was heard in the background, and it was the sound of The Inevitable. Red turned her attention to the Inevitable, and left Maisie and Jacob.

The Red Bluster attempted to attack The Inevitable as well, but stopped when Captain Crow injected her with a poison that Gwen Batterbie had created. The poison make her unconscious, which allowed the sea hunters to tie her in rope, and drag her Three Bridges, where Captain Crow planned to kill her.

At Three Bridges, just as Captain Crow was about to stab her with a spear, he was stopped by Jacob Holland. Meanwhile, Maisie was secretly cutting the rope using her small knife. She was found by Sarah Sharpe, who cut the rope with her larger knife in one go. The Red Bluster was free from the rope and collapsed on different parts of the kingdom, damaging the building. She saw Captain Crow and went directly to kill him, only to be stopped by Maisie. Maisie gave a speech on the origins of the sea monster lore and accused the royal family of inventing the story for their own benefit. She explained that sea monsters had learned to become violent, as a result of being attacked by hunters. As people realised the truth, they turned against the king and queen, who ran away. The Red Bluster was set free.

Trivia

 * According to director Chris Williams, the Red Bluster needed to be both appealing and ferocious. She was the most powerful creature in the world, but the producers didn't want her to look scary. They wanted her to be appealing in a very divine way.
 * The team hired a sculptor to craft a clay model that would define even the beast's internal musculature. There were also a few story-based requirements that helped set guardrails for Red’s design process.
 * Unlike other monsters in the movie, Red had no one-to-one real-world analogue. The creature in the film is a pure fantasy, with a few qualities borrowed from real ocean creatures.
 * For inspiration, the team looked into walruses and how they navigate in the water. They also looked at whales, turtles and sharks.
 * The Red Bluster originally had front and hind legs, the producers felt that paddling in the water like a cat was not elegant.
 * The Red Bluster's eyes were inspired by cat eyes.
