Alex, a human girl version of Tails, basically

Alex, a human girl version of Tails with fox ears and tail and golden hair, with human skin still and no fur, a jumper that she puts on without realising when she's tense or sad, stronger than she looks and smarter, picks up any instrument and plays a level 80 song on it during the first minute, doesn't fit in except with Tails and the others, bad joker, but enough to make you laugh, who loves black shorts and crop tops with yellow striped hoods and black, who dives headfirst into everything, who lost everything on her 13th birthday by fire right before the Metal Virus (her family, her home, her friends and her whole neighbourhood)
