Let's blast through with sonic speed!
— Sonic the Hedgehog, Sonic Heroes
Team Sonic (チームソニック Chīmu Sonikku?), also known as Team Heroes (チームヒーローズ Chīmu Hīrōzu?), is a reoccurring group in the Sonic the Hedgehog series. The team was founded by Sonic the Hedgehog, Miles "Tails" Prower and Knuckles the Echidna to stop one of Dr. Eggman's plans for world domination, who later turned out to be Metal Sonic in disguise. With its primary members having at least one talent at which they are virtually perfect at, Team Sonic is a highly capable team who has overcome several threats to the world.
Team Sonic made its first appearance in Sonic Heroes as one of four teams playable in the game. At the start of Team Sonic's story, Sonic is running through a desert when Tails and Knuckles arrive in a plane. Tails hands him a message from Dr. Eggman, saying that in three days, he will conquer the world. Up for a challenge, Sonic goes to stop him. Tails and Knuckles come along as well, forming Team Sonic.
This team's levels are for intermediate players of the game, and contain a variety of high speed sections. Their extra missions involve completing the stage in a certain time limit. Team Sonic's Team Blast is Sonic Overdrive. In the team "Super form", Team Super Sonic, the Team Blast is Super Sonic Power.
Sonic Riders series
In this series of games, the team is mainly referred to as Team Heroes, and appear as the protagonists in all three entries of the series.
The team returns in Sonic Riders. Sonic, Tails and Knuckles encounter the Babylon Rogues (a group of thieving birds who ride Extreme Gear) who steal an emerald that the team was tracking. The next day, the three watch an announcement made by Dr. Eggman advertising the EX World Grand Prix, when Sonic discovers that the Babylon Rogues have entered the race. The trio signs up as Team Sonic and serve as the playable characters in the hero's story alongside Amy Rose. The members of each team develop a rivalry against their respective character. During the course of Sonic Riders, Wave criticized the handling of Tails' Extreme Gear, but this later helped Tails beat her in a race. In a Grand Prix race sponsored by Dr. Eggman, Sonic was just about to win, but was unaware of a bomb on his board. Wave detonated the bomb, causing Sonic to wipe out and Jet to unfairly win. In the Babylon Garden, Team Sonic, the Babylon Rogues and Amy faced off against the Babylon Guardian, and later found out the treasure of Babylon was a Flying Carpet. Before the credits rolled, Sonic gave Jet his box back, seeing as the Rogues needed it more.
Sonic Riders: Zero Gravity
In Sonic Riders: Zero Gravity, Tails received a news report of MeteorTech robots going berserk. One of the berserk robots attacks Sonic and company, who proceeds to chase it. The team later finds a circular stone which was later revealed to control gravity. The team arrives at ruins, and Knuckles proceeds to examine it. On closer inspection, Knuckles infers that the ruins spoke of a "lightless black". Later, as Team Heroes and Amy meet up, the Babylon Rogues arrive and demand Sonic to hand over the Ark of the Cosmos, which was the circular stone that Sonic, Tails and Knuckles found. The team then collects the Arks of the Cosmos and lets Jet keep them as Sonic has no need for them. However, a MeteorTech Robot steals the Arks, and Team Sonic and the Babylon Rogues proceed to defeat the robot and retrieve the Arks before they get sucked into the massive black hole. Later, Tails talks about the ruins' message to Sonic and Knuckles, telling them that it was a warning about using the Arks. Jet then appears and has a friendly race with Sonic.
Sonic Free Riders
In Sonic Free Riders Sonic, Tails and Knuckles teamed up for the second World Grand Prix and competed against the Team Rose, Team Dark and Team Babylon for the title of the best Extreme Gear riding team in the world.
In the crossover series Mario & Sonic, Team Sonic is expanded out to every character who originated from the Sonic the Hedgehog series. Sonic, Tails, Knuckles, Amy, Dr. Eggman, Shadow, Vector and Blaze are all included in Team Sonic. In the sequel, Mario & Sonic at the Olympic Winter Games, two more members joined Team Sonic: Silver the Hedgehog and Metal Sonic. Jet, Rouge, Sticks, Espio, Omega, Dr. Eggman Nega, Wave, Cream, Zazz, and Zavok joined Team Sonic in Mario & Sonic at the Rio 2016 Olympic Games.
Sonic Runners series
Team Sonic returns as the main protagonists of Sonic Runners, which revolves around their constant attempt to stop a series of plans set by Dr. Eggman and to discover what exactly his true plan is. Though all three members appear together from the very start of the story, only Sonic is playable by default within the gameplay, while Tails and Knuckles must be unlocked.
While Tails and Knuckles must be unlocked, they appear as the earliest playable characters (alongside Sonic by default) and also the only ones who can be unlocked through Story Mode. In this game, all three members are classified as Hero Type characters and retain their ability formation of Speed, Fly, and Power.
Sonic Runners Adventure
Whilst Team Sonic did not officially appear until Sonic Heroes, there have been several instances throughout the series where all three characters have worked together or teamed up.
The first instance of this happening is in Sonic the Hedgehog 3 & Knuckles, if the player chooses to play as Sonic and Tails. During the game's climax at Hidden Palace Zone, Dr. Robotnik reveals his true colors to Knuckles and steals the Master Emerald. After an unsuccessful attempt to retrieve the Emerald from Eggman's clutches, Knuckles assists Sonic and Tails, leading them to a hidden room with a teleporter to Sky Sanctuary Zone. Upon arrival, Knuckles, already weakened from his short bout with Robotnik, offers one last bit of assistance to the duo by opening a bridge to the rest of the Sanctuary. Upon recovering the Master Emerald, Sonic and Tails cement their friendship with Knuckles and leave Angel Island on good terms.
In Sonic Triple Trouble, while Knuckles is enemies with Sonic and Tails for most of the game (due to Dr. Robotnik's lies), at the very end, he is the only antagonist out of the main three (the others being Nack the Weasel and Robotnik himself) who decides to make peace with the heroic duo and befriend them as well, sharing a handshake, escaping together from Robotnik's base, the Atomic Destroyer.
In Sonic 3D Blast, Sonic, Tails and Knuckles travel together to Flicky Island to visit their Animal friends. Tails and Knuckles help Sonic defeat Dr. Robotnik by helping him collect the Chaos Emeralds, letting him access the Special Stages.
In Sonic R, Sonic, Tails and Knuckles (plus Amy) work together to prevent Dr. Robotnik and his robotic minions from gathering all the Chaos Emeralds in the Grand Prix Tournament.
In Sonic Adventure, Tails and Knuckles assist Sonic in the final battle against Perfect Chaos, by bringing him the energy-drained Chaos Emeralds and are the first to arrive, helping Sonic go Super; they also cheer him during the battle. The trio is seen standing together in a platform after Chaos' defeat.
For the majority of Sonic Adventure 2, Sonic, Tails and Knuckles do not work together. However, after Knuckles has completed Aquatic Mine, he joins forces with Sonic and Tails, although when the group reaches outer space on their way to Space Colony ARK, Knuckles goes to find the pieces of the Master Emerald accidentally jettisoned from the shuttle the trio were piloting.
Through the Sonic Advance series, Tails and Knuckles are unlockable characters who join Sonic at different points during his adventures.
In Sonic the Hedgehog (2006), Tails and Knuckles assist Sonic during Sonic's storyline. Occasionally during Sonic's levels, Tails or Knuckles may take over and become playable for a brief section of the stage. In Town Mission 8: The Legend of the Three Musketeers, the player must play through three parts of the mission as Sonic, Tails and Knuckles.
Sonic, Tails and Knuckles appear as playable characters in Sonic Chronicles: The Dark Brotherhood. Sonic appears as the main character whilst Tails and Knuckles are recruited to the player's party later on. When Tails and Knuckles are in Sonic's party, the three can perform a special POW move called the Triple Tornado, and with the addition of Amy, the Hail Storm. Their team name is also said twice by Shadow.
In Sonic Mania, the trio work and are seen together several times, acting as allies to Sonic through the game.
