This proposal is about Tails .
WHO IS HE / WHAT HAS HE DONE?
Miles "Tails" Prower is the deuteragonist and secondary protagonist of Sonic the Hedgehog video game series. He is Sonic's best friend and sidekick (but also adoptive brother), he is one of the smartest characters as well with an IQ that rivals that of the evil genius Dr. Eggman despite Tails being much younger: he is especially good at inventing and spends a lot of his time making new things. Although officially named Miles he doesn't like being called that, he prefers to be addressed simply as Tails and this is the name almost everyone refers to him as in the series (though in one of the cartoons Sonic threatened to tell everyone Tails real name but didn't do so).
Tails is very close to Sonic and sees him as his best friend (including Norton), in many ways Sonic shares these feelings but doesn't always show it - which can cause irritation or sadness on Tails part, in general though the two get along well and when arguments do break out they are normally resolved without violence (though the famous duo have clashed once or twice due to differences of opinion).
Tails is a gentle, sweet-natured and loyal fox cub with a positive attitude and a giant heart. In the beginning, he was fearful and cowardly, but he gained independence and became more stubborn over the years. Tails is not the selfish type and, instead, he is a pretty innocent and selfless boy, and is always ready and willing to help others without asking for anything in return.
Despite being only 8 years-old, Tails is very intelligent for his age (being declarated to be the most intelligent character in the Sonic series) and loves studying, especially when it involves science and mechanic, for which Tails holds a great love for. He finds himself most at home in his workshop working in his next creation (which usually serves to help his friends out, like Sonic). Despite his great skills, Tails is very humble about hus abilities, never giving them many thoughts, though he has yet to discover his true potential of what he can accomplish. At the time of Sonic Lost World, Tails has become more confident and even playful about his intelligence, though he still does not openly brag.
I think he would be the perfect candidate to be approved
