Miles Prower (CAV-4)

Miles Prower, better known as Tails, is the resident kid genius and Sonic's unofficial little brother. While he can sometimes come off as a bit of a know-it-all, he's just incredibly smart and tends to forget that not everyone can keep up with him when he starts talking about the finer intricacies of, I don't know, different kinds of rocks. Physics. Whatever he decides to be the exposition fairy for this week.

He finds it difficult to form his own identity separate from Sonic after spending so long in her shadow, but after helping save the day a few times on his own he's finally starting to make a name for himself.

While trying to stop Eggman from capturing Wisps en-masse for access to Colour Power, Tails got kidnapped and was used as a test subject for both roboticization and Negative Colour. He was able to escape full conversion with some quick thinking and sabotage, but had his personality completely overwritten by the latter until Sonic broke Eggman's control over him. The experience is something he'd rather forget, but while he's able to shapeshift his robotic limbs somewhat in order to use his buster he's not able to hide them completely and hasn't had any luck in finding a way to revert the changes.

Tails also makes friends with Sik over the course of Forces, and is the one responsible for putting together Sik's prosthetic leg and later creating the Gravity Band. They actually get pretty close, and are dating by the time the Bridge happens.
