Sebastian (full name Horatio Thelonious Ignacious Crustaceous Sebastian) is a crab and one of the main protagonists in Disney's 1989 hit film The Little Mermaid, its prequel film, its TV series, and its sequel.

Sebastian also appears in the Kingdom Hearts series of games, in which he is voiced by Kōichi Yamadera in its original Japanese version, and by Kevin Michael Richardson in the English-language version.


Sebastian, a sidekick for The Little Mermaid's protagonist Ariel, is a character developed solely for the film, and is not derived from the original Hans Christian Andersen story.

Sebastian was conceived as a musical character for The Little Mermaid, and performs two songs ("Under the Sea" and "Kiss the Girl") that went on to become hits for Disney and were nominated for "Best Original Song" at the 1990 Academy Awards. Voice actor Wright's singing style and the compositions by Howard Ashman and Alan Menken for the Sebastian character lean heavily to calypso and reggae influences.

Sebastian's back story is that he was born off the coast of Jamaica to Claude and Claudia Sebastian and went to school in Trinidad.

The Little Mermaid appearances

The Little Mermaid

When the film opens, Sebastian is announced as being the "royal court composer", and conducts a concert that King Triton's seven daughters are supposed to perform in. Ariel, the youngest daughter, fails to show up for the concert, and later Sebastian joins King Triton in scolding her, blaming her for his humiliation. King Triton, worried about Ariel, tasks Sebastian with following Ariel and keeping her out of trouble.

Sebastian tries to do the job given to him, and is horrified when Ariel saves the life of and falls in love with a human. Sebastian accidentally lets this information slip to King Triton, who confronts Ariel. Feeling guilty for having "betrayed" Ariel, Sebastian follows Ariel when she visits Ursula the sea witch for help, and later becomes an adviser in her quest to win Prince Eric's affections. He also makes an enemy out of Chef Louis.

In the film, Sebastian starts out in a parental, supervisory role over Ariel, and over time, he becomes her close friend.

The Little Mermaid television series

Sebastian appears in every episode of the prequel television series, which follows the adventures of Ariel when she is still a mermaid. In the series, Sebastian's occupation is King Triton's assistant, adviser and confidant. Sebastian is shown as being a good friend of Ariel and Flounder, as well as Urchin, a new character unique to the television series. He is sometimes strict and often critical of Ariel's adventurous ways, but often ends up going on her adventures with her.

In one adventure, in the episode "Island of Fear," he accompanies Ariel as she tries to find the source of a pollutant that is sickening the fish. He befriends a human boy named Daniel, and helps the boy to escape from the evil scientist the boy is forced to work for. This makes it one of the few times in the series that a character directly interacts with a human.

Throughout the series, Sebastian's character is further developed via dialogue and entire episodes dedicated to him. In the series, Sebastian is said to have come from a large Jamaican family. Apparently, Sebastian was born in Jamaica and went to Music Academy in Trinidad prior to joining King Triton's staff as his assistant. "T'ank You for Dat, Ariel" reveals that he is somewhat insecure regarding his size.

The Little Mermaid II: Return to the Sea

In the sequel, Sebastian is tasked by King Triton to watch over Ariel's daughter, Melody, repeating his role from the original film. When Melody was dressing up for the party, she unknowingly tied Sebastian to her dress with a ribbon, and when Melody was dancing with a boy, Sebastian pinches him, and while he did get free, it somewhat ruined the party for Melody. He also has another run-in with Louis.

The Little Mermaid: Ariel's Beginning

In the 2008 prequel, Sebastian is King Triton's attaché, and is initially shown as being a strict enforcer of the sea king's rules. All music has been banned from Aquatica, but it is later revealed that Sebastian has been secretly performing music as the leader of The Catfish Club Band, which performs in an underground club. Technically, this makes Sebastian the first character in The Little Mermaid universe to break a major law of Triton's.

When the underground club is revealed to Triton, Sebastian is placed in jail with the rest of his band. Thanks to Ariel, they manage to escape. As part of a premeditated plan, Sebastian leads them far away from Aquatica to a specific spot where Ariel finds her mother's discarded music box. Sebastian wants music to return to Aquatica, and he returns with Ariel to convince Triton to change his mind. When the film ends, music is restored to Aquatica, and Sebastian becomes the "royal court composer", setting up his role in the opening of the original film.

According to this film, Sebastian is the eldest of Ariel's friends, having been present since she was a small child all the way to her own parenthood in The Little Mermaid II: Return to the Sea.

Other appearances

After Goofy talks about looking for the Keyhole, Sebastian, like Ariel, becomes interested in it as well.

He helps them get into Ursula's Lair by pressing a button in the wall no one else could reach.

Kingdom Hearts II

In Kingdom Hearts II, Sebastian's musical abilities from the movie are finally shown. He is trying to use musical practice to get Ariel's mind off the surface world. When Sora and the others say that they will help her, Sebastian gets mad not wanting them to help her find Prince Eric. Sebastian in the game writes Under the Sea to help Ariel want to stay in the ocean where she belongs. Ariel is instead saddened by the song and yearns for Sebastian to write a song about land and sea living in harmony, making Sebastian frantic over the fact that King Triton would find out about this. Sebastian goes a little bit too far when in his monologue, he spills the fact that Ariel is in love with a human. King Triton happens to be right behind him, hearing the confession and is deeply angered.

After Ariel changes into a human, Sebastian tries to help her kiss Eric in time. After Ariel and Eric defeat Ursula, King Triton finally allows Ariel to marry Eric even though Sebastian is a crab. Seeing this, Sebastian complies with what Ariel once said earlier in the sea, and writes A New Day is Dawning to show how the two worlds can join together in harmony.
