Which Sonic game introduced the character Tails?

Which Sonic game introduced the character Tails? It was Sonic the Hedgehog 2. Released in 1992 for the Sega Genesis, the sequel introduced Miles “Tails” Prower, a young yellow fox with two tails who becomes Sonic's longtime partner and sidekick.

Tails' two tails are not merely a visual trademark: in Sonic the Hedgehog 2, he can spin them like a propeller to fly briefly. In the original Genesis version, a second player could control Tails while the first played as Sonic, helping establish the cooperative character dynamic that became central to later Sonic games.

His real name, Miles Prower, is a pun on “miles per hour,” matching Sonic's speed-focused identity. The nickname “Tails” refers to his unusual twin tails. Players sometimes confuse Sonic the Hedgehog 3 with his debut because that game expanded his abilities and role, but the character himself first appeared in Sonic the Hedgehog 2. Sonic CD instead introduced Amy Rose and Metal Sonic.
