Miles "Tails" Prower

"A young fox with two tails and a loyal friend of Sonic. By spinning his tails, he can fly like a helicopter."

- Sonic Mania's description manual.

Miles Prower, commonly known by his nickname Tails, is the deuteragonist who is a two-tailed fox (hence the alias) and is incredibly intelligent as well. He owns his Tornado bi-plane and helps his best friend Sonic the Hedgehog defeat the other evil genius, called Dr. Robotnik, together with his creation Metal Sonic.

Sonic Generations
Whilst Sonic was roaming Green Hills, a weird monster sucks in Sonic friends, including Tails, into a white limbo. He comes across his Modern counterpart and meets up with the two Sonics. He and Modern Tails both figure out that everyone who has been taken to the White Space are traveling through time and space. The Time Eater appears and roams around the area before leaving once more. Classic Tails runs at the happening and asks Tails and the Sonics where it went. The Sonics decide they need to stop the villain as fast as they can and restore the old zones which are trapped in the White Space.

At the now restored Seaside Hill, the four Tails' and Sonics meet up together once again. Although, the Time Eater appears once again, leading to Classic Tails to explain how the Time Eater causes the left-over zones to become lifeless and stuck inside a white nothingness. Sonic and his counterpart hurry once more before there is no tomorrow left.

Classic Tails, his buddy and Modern Tails all go to a Boss Gate that the Modern counterpart of Sonic goes back out from after battling Chaos. The classic Tails high-fives Sonic's double, but states he won't get used to saying 'Sonics'. The monster appears again, trying to snatch a lifeless emerald, but jumps back from it's weird power. Tails points this out and is sure that Sonic and Modern Sonic need to go get the emerald so they can defeat the enemy.

Modern Sonic has beaten the Egg Dragoon and the rest come check out the outcome. Classic Tails descends with his best friend in his hands, he lands and sees the Modern Robotnik in demise. The Time Eater later catches him up, into another portal. Classic Tails finds this situation to get stranger and stranger.

They collected the Chaos Emerald and freed their friends, now they only need to shut down the Time Eater's evil plans. But then, it unveils that Dr. Eggman and Dr. Robotnik are behind this scheme. The two antagonists have "defeated" the Sonics, but their friends (including Tails) cheer them on. With the help of the Chaos Emeralds, Classic and Modern Sonic have defeaten the Time Eater once and for all. They then say there last goodbyes to their counterparts and return home.

Sonic And Tails
Tails is working on the Tornado and sees a blur crossing by. He looks up to see his friend Sonic on the wing, who winks at Tails. Sonic throws a strange device for Tails to catch and look at. He reads that there is in fact an emerald nearby. Sonic runs at it and leaves Tails behind.

Sonic plummets back into the sand with lost rings and an injured face. Tails walks up to him and lends a hand to help him up to defeat Dr. Robotnik who is using his drill machine to claim the emerald.

Sonic jumps on Robotnik's machine which irritates him, but Tails then hits him as well. Robotnik puts on a terrified face before being attacked multiple times. He tries to attack Sonic with a drill, but Tails jumped right in time to save him from his doom. Above Robotnik, he helps spin Sonic into Robotnik's machinery, destroying it. Robotnik blasts off and Tails clings the emerald with Sonic's, laughing at the end.

Mighty And Ray
Tails is seen racing towards Robotnik's Lab alongside Sonic and is about to help defeat him and his schemes.

Metal Mayhem
Tails and his companion, Sonic, arrive at the lab expecting Robotnik's appearance. Although nowhere to be seen, his creation Metal Sonic appears out of nowhere and freezes the duo. Metal drops the boxes and snatches the emeralds. Tails is dizzy by the drop. Robotnik appears with the emeralds and Metal with the two others. Sonic gets ready to fight Metal Sonic, who is now in a super state. Tails facepalms and evades the attack of Metal Sonic to Sonic. After Mighty the Armadillo punches Metal away from the hedgehog, Tails greets him and Ray before all fighting the replica of Sonic. Tails and the rest charge at the villain in full force. Tails fiercely kicks him in the face, but gets slapped away by the claws of the robot.

With a heavy breath, Tails has a plan on how to defeat Metal Sonic and he needs Sonic's help. Sonic surrounds Metal Sonic, running at a fast speed, whilst Tails pulls up a freeze box to freeze him. The idea works and the box drops him, releasing the emeralds. However, the Master Emerald appears underneath Metal Sonic. Tails and his friends gaze upon it until Knuckles angrily punches Metal out of the lab, together with Robotnik. After the events of the lab and Knuckles taking away the emerald from it, Tails joins Sonic, Mighty and Ray in a chilidog picnic. He unfortunately coughs from the heat.
