Miles "Tails" Prower is an anthropomorphic nine-year old, two-tailed fox who is Sonic the Hedgehog's best friend and sidekick throughout their adventures together. He is also a master mechanic, strategist, inventor and air pilot.
Tails is a young, anthropomorphic fox with the unique mutation of giving him two tails instead of one. He has mostly orange-yellow fur with white fur around his muzzle, front torso, and the tip of his tails, and has blue eyes.
Tails wears a pair of white gloves and socks with small gray fasteners on his hands and feet. He also wears a pair of red sneakers with white toes and gray soles. He even wears a brown work belt with a shoulder strap around the front and back of his body, and a pair of brown work goggles on his head.
Tails is gentle, sweet-natured and loyal with a positive attitude. When young, he was initially timid and shy, but he has opened up and become more outgoing over the years. Tails is not one to grab the spotlight for himself and is instead always ready to willing help others without asking for anything in return.
Tails has a distinct love for mechanics and he finds himself most at home in his workshop working on his next creation. Despite his great skills, Tails is very humble about his abilities, never giving them many thoughts, though he has yet to discover his true potential of what he can accomplish. As the series progressed, Tails has become more outspoken about his intelligence, though he still does not openly brag.
When young, Tails often lacked self-confidence and courage. After meeting Sonic and gaining his support, Tails gained more confidence and belief in himself. However, this status quo, created from Sonic's authority over him put a mental stranglehold on Tails that made him dependent on Sonic. As such, he often lacked directions and confidence whenever he was on his own. A turning point for Tails came when Station Square was in danger of being destroyed, Tails was the only one who could stop this. With Sonic nowhere to be found, Tails realized that he could not depend on Sonic forever and had to try on his own. After saving Station Square, Tails realized he could be independent and support himself without Sonic, and all he needed was determination and faith. Since then, Tails has become more independent, self-confident, motivated and brave, and can as well rise up to be a real hero when needed.
During their earlier adventures together, Tails strove to become just like Sonic by replicating the mannerisms he found admirable. In this period, Tails was content with being Sonic's sidekick as he was just happy to hang out with Sonic. As Tails grew as a person, he still remained as close to Sonic as ever as his sidekick and still looks up to him, but his esteem about Sonic's heroics have dwindled, as he these days cares more about inventing then Sonic's heroic deeds.
Despite his development, Tails still tends to depend on Sonic when he is in a moment of weakness. However, he hopes to one day be self-sufficient and independent like Sonic, while proving he can be relied upon. Also, even though Tails still enjoys being Sonic's sidekick, he believes that he can do almost anything if he puts his mind onto it.
Despite his intelligence and general fearlessness, Tails is afraid of lightning and can be naive and big mouthed. Tails also hates feeling useless or being ignored, as seen in the cases when he is talking to Sonic. He also gets very angry when someone dismiss his mechanical skills and takes it very personally, as seen when Wave the Swallow mocked his self-customized Blue Star. Tails also has a tendency to talk techno-babble, much to the irritation of his friends, such as when he tried to explain how an Extreme Gear worked, meaning that Tails does not always use tact in a situational matter. Nevertheless, Tails is supportive of his friends, willing to be by their side no matter what or how dangerous the situation might be, and do whatever it takes to help them, even if it means sacrificing himself for them.
Despite his young age, Tails is hailed as a natural genius for his immense intellect and natural talents in all sorts of mechanics and science, and was Sonic the Hedgehog's equal partner when ever the young fox would go on missions with the heroic hedgehog.

When there's a machine, I couldn't help but make or fix it.
(to Sonic the Hedgehog) - You did it, Sonic!
(about Sonic) - I've relied on Sonic to protect me for too long. I know that I can fight my own battles... because I have to believe in myself!
(to Wave the Swallow) - You're gear is still as amazing as ever, Wave.
I've changed a lot since I've started hanging with Sonic... but I can't depend on him forever. I know I can do this by myself! Okay, Eggman, bring it on!
(cornered by the Egg Walker) I'm not scared! I'm not scared! I can do this!
(to Cream the Rabbit) That's a pretty impressive Gear you've got, Cream! You'll have to show me later!
(about Sam Spartan) Sam, you have been a wonderful friend and technical helper I've loved, though Sonic and I have been through together, and I think it's time we've shown our friendship with each other.
But why would Kisame want to attack Cream?
This is seriously bad, Sonic! We have to get Cream to a safer place where Kisame won't notice!
Kisame, how I hate this jerk so much!
Naruto, I call upon the power of the Kitsune to give me the power of speed.
Please don't cry, Cream. You're still safe from Kisame for now. Everything is going to be alright. I promise it's going to be okay. I promise.
You don't have to apologize, Cream. Now let's get out of here before Kisame notices us again.
