Tails Sonic Movie Character: Voice, Story and Fate
Tails, Sonic's sidekick in the movies, is a fox with two tails, and Colleen O'Shaughnessey voices the character in all three Sonic films. Tails first appears in the mid credits scene of Sonic the Hedgehog (2020), then joins the heroes properly in Sonic the Hedgehog 2 (2022) and Sonic the Hedgehog 3 (2024), all three directed by Jeff Fowler.
Who Plays Tails (voice)?
Who Is Tails in the Sonic Movies?
Tails, full name Miles "Tails" Prower, is a fox with two tails who serves as Sonic's partner and teammate across the Sonic films, and the character is an animal, not a human. The character comes from the Sega games that the films adapt. The credits list the role as "Tails (voice)" in sonic 2 movie and sonic the hedgehog 3, while the cameo in sonic the hedgehog 2020 was voiced by Colleen O'Shaughnessey without a credit.
Tails is a boy, and the films refer to the character as he. Colleen O'Shaughnessey voices every appearance, from the 2020 cameo to the third film, so the sidekick never changes voice partway through the saga. That is a small comfort for any parent who has watched another franchise swap a favorite character's voice. The most recognizable trait, the pair of tails, carries over too.
All three films carry a PG certification in the US, the UK and Australia, which makes Tails a gentle way into the saga for younger viewers. If you want the wider cast around the fox, the sonic characters page lists every main player, and the sonic cast page covers the actors.

Tails Story Arc Across the Three FilmsSpoilers
Tails goes from a one scene teaser in the first film to a full member of the team by the third. The arc is short on screen time but clear in direction.
In Sonic the Hedgehog (2020), Tails appears only in the mid credits scene, arriving through a ring portal to find Sonic while Robotnik sits stranded on the mushroom planet. It is a sequel hook and nothing more, but it promises that Sonic will not be alone for long.
In Sonic the Hedgehog 2 (2022), Sonic is settled on Earth when Tails comes along to help him face a new danger. The two race to find the Master Emerald before Dr. Robotnik and Knuckles can, and their trip is disrupted by an ambush at a wedding involving G.U.N. and then by an avalanche. After Robotnik betrays Knuckles, takes the Emerald and leaves both Sonic and Knuckles to drown, Tails arrives in a biplane and rescues them. The action then moves to Green Hills, where the Master Emerald breaks into seven Chaos Emeralds and Sonic uses them to become Super Sonic.
In Sonic the Hedgehog 3 (2024), G.U.N. sends Sonic, Tails and Knuckles to Tokyo to catch Shadow, who has been released from a prison facility. Shadow escapes, and from there the heroes learn his history, track Ivo Robotnik's drones to an abandoned G.U.N. base and team up with Agent Stone to stop the Eclipse Cannon.
Is Tails Sonic's Best Friend? Relationships Explained
Tails is Sonic's closest ally in the sequels, and the other relationships in the films grow out of that partnership. In Sonic the Hedgehog 2, Tails comes along specifically to help Sonic face the new danger, and the two set out together to find the Master Emerald.
Knuckles starts as an opponent. He teams up with Robotnik to hunt the Master Emerald, is double crossed, and then Tails arrives in a biplane to rescue him alongside Sonic. By the end of the film Knuckles, Sonic and Tails promise to protect the Emerald together, and the three return in the third film as a trio. For more on the echidna, see knuckles sonic movie.
Dr. Robotnik is the threat that sends the heroes racing in the second film, and the family name returns in the third with Ivo and Gerald. Read more on dr robotnik.
In the third film, Tails shares the Tokyo mission with Sonic and Knuckles against shadow the hedgehog movie. The team also joins forces with agent stone sonic, Ivo's assistant, and works with Tom and Maddie (see tom wachowski sonic and maddie wachowski sonic). Sonic himself is covered under sonic the hedgehog character.
What Happens to Tails at the End?Spoilers
Tails is alive at the end of every film in which the character appears. In the first film, the fox appears only in the mid credits scene, arriving through a ring portal to find Sonic. In the second, Tails survives the Green Hills battle in which Robotnik is lost with his giant robot, and stands with Sonic and Knuckles as they agree to guard the Master Emerald.
In the third film, the closing stretch is darker for others than for Tails. Gerald dies in the reactor core after revealing he wanted to destroy the Earth for Maria's sake, and Ivo and Shadow give themselves up to push the unstable cannon core away from the planet. Sonic survives and reconciles with his friends and family.
If you are wondering what comes next, Paramount set the US release of sonic 4 for March 19, 2027, and the film is now in post production. For how the films connect, the sonic movies in order page lays out the sequence, and the sonic timeline page follows the story.
Best Tails Moments in the Sonic Films
In my opinion, the biplane rescue in Sonic the Hedgehog 2 is the best Tails moment in the saga. Sonic and Knuckles have just been left to drown by Robotnik, the film has been playing the two as rivals, and the sidekick shows up from the sky to save both. It could be argued that the scene does more for the team dynamic than any speech, because it gives Tails a practical job instead of a joke.
Perhaps the neatest piece of franchise planning is the 2020 mid credits cameo. The fox arrives through a ring portal in the final moments, and a casual viewer leaves the theater knowing exactly who is coming next. Compare that with the second film's own tease, where Agent Stone overhears G.U.N. discussing a facility tied to Project Shadow: both are sequel hooks, but the Tails one is the more cheerful of the two.
The third film gives Tails the least individual spotlight, which is fair given that Shadow, Gerald and Ivo take most of the story. Still, the Tokyo chase and the push to stop the Eclipse Cannon show a team that works. If your child asks which film to start with for Tails, I would point them to the second, since that is where the fox truly gets to play a part.

FAQs
What kind of animal is Tails?
Tails is a fox with two tails, and not a human. The mid credits scene of Sonic the Hedgehog (2020) introduces the character as a two tailed fox arriving through a ring portal, and the character stays a fox in the two sequels, alongside Sonic and Knuckles, who are not human either.
Who voices Tails in the Sonic movies?
Colleen O'Shaughnessey voices Tails in all three films. She is uncredited for the 2020 cameo and credited as "Tails (voice)" in Sonic the Hedgehog 2 and Sonic the Hedgehog 3. Game casting, including Sonic Adventure 2, is separate from the film credits, so this answer covers the movies only.
Why did Tails betray Sonic?
In the movies, Tails does not betray Sonic. The betrayal in Sonic the Hedgehog 2 is Robotnik's, who double crosses Knuckles, takes the Master Emerald and leaves Sonic and Knuckles to drown. Tails arrives in a biplane and rescues them.
Is Tails a girl or boy in Sonic?
Tails is a boy. Miles "Tails" Prower is a male fox, and the films treat the character as he, even though Colleen O'Shaughnessey, a woman, provides the voice.
Why is Tails always voiced by a girl?
Tails is voiced by Colleen O'Shaughnessey in all three Sonic films, and none of the sources for the films gives a reason beyond casting. Voice actors of one gender often play characters of another, particularly young animated characters, so it is a casting choice and not a story point.
Is Tails actually 8 years old?
The eight year old figure comes from the Sega games, not the films. None of the three Sonic films states an age for Tails on screen, so the movie answer is that no age is given.
