Tails

Miles Prower, better known by his nickname "Tails", is a two-tailed yellow fox from the  franchise, and the sidekick and best friend of Sonic. He is a mechanical genius who has the ability to spin his tails like a propeller, and thus fly. In Mario & Sonic at the Olympic Games and Mario & Sonic at the Olympic Winter Games, he is voiced by Amy Palant, but in Mario & Sonic at the London 2012 Olympic Games, he has been voiced by Kate Higgins. Since 2014, he has been voiced by Colleen O'Shaughnessey. "Miles Prower" is a pun on "miles per hour".

Mario & Sonic at the Olympic Games

Mario & Sonic at the London 2012 Olympic Games
Tails returns as a playable Skill type character in the Wii version of Mario & Sonic at the London 2012 Olympic Games. He appears in the opening with all of the other athletes, as well as competing in Uneven Bars and Dream Hurdles. Tails appears as one of the characters that can be spoken to in order to play a minigame and earn stickers in London Party mode, and a Mii outfit based on Tails can be unlocked.

In the Nintendo 3DS version, Tails is included in the Heroes group, alongside Mario, Sonic, and Luigi, meaning that he is only playable in certain Events. In the Story Mode, Tails first appears alongside Sonic when they arrive at the Tower of London and find red Phantasmal Fog, which they clear up and conclude that Bowser is involved with it. The next day, the pair head to Tower Bridge, where they find more Phantasmal Fog and clear it up with the help of Yoshi, Shadow, Silver and Jet, allowing the bridge to be lowered. They also learn from Bowser Jr. that Dr. Eggman is also partly responsible for the fog, so Tails and Sonic head to the British Museum to continue investigating. At the museum, Tails and Sonic find and team up with Mario, Luigi, and Toad, and the group clear the fog from the area and head into the museum to find some more information about the Phantasmal Fog, which Tails manages to do. The group then splits up, with Tails following Espio to ExCeL London where they find that Omega has had a chip installed by Dr. Eggman, and remove it with Donkey Kong's help. Tails, Espio and Omega then head back to the Main Stadium, and Tails helps rescue Cream from some imposters when the fog returns. Tails then heads to Stonehenge with Mario, Luigi, Toad, Sonic and Omega, where they find the lid for the Fog urn and learn from Omega that Bowser and Dr. Eggman are hiding inside Big Ben. The group head there, and Toad passes the walkie-talkie onto Tails before he and Omega leave the group. The Heroes head into Big Ben to confront Bowser and Dr. Eggman, and after they have been defeated, Tails goes with them to the Main Stadium so that they can register for the Olympic Games, later appearing at the opening ceremony. A badge of Tails can also be obtained from the badge machine.
