Visual effects for the creature were provided by Weta Digital in Shang-Chi and the Legend of the Ten Rings, which supplemented its winged, tentacled, and eyeless appearance with a large jaw and tongue.

In 2026, during Danvers's team-up with Monica Rambeau and Kamala Khan, Goose is overseen by the agents of S.A.B.E.R., and begins breeding Flerken eggs around the station, giving birth to numerous offsprings which eventually help evacuate the agents when the S.A.B.E.R. station begins to collapse. She was introduced in Captain Marvel and returned in The Marvels. Hand-drawn pictures of her were seen in Ms. Marvel and she was mentioned on Fury's file in Secret Invasion.

The Great Protector can bestow her power onto people, giving them the ability to manipulate wind; and her scales can be fashioned into weapons and armor that are effective against the Dweller's forces. A life-sized replica of the dragon's head was built for the production of Shang-Chi and the Legend of the Ten Rings, which Weta Digital then digitally added visual effects to. Weta also based the dragon's eyes on those of Fala Chen, who portrays Ying Li in the film, and referenced sea snakes and eels when designing her flight movements.

Visual effects for the creature were provided by Trixter in Shang-Chi, who looked at wombats and puppies for inspiration.
