Fiona Fox is 16 years old in Sonic the Hedgehog.
There are two foxes in the Sonic the hedgehog series. The most well-known fox is Miles "Tails" Prower- Sonic's two-tailed sidekick. The other being Fiona Fox, appearing exclusively in the comic series.
Depends. Someone on wikianswers said his birthday on sonic x was December 4 1997, but I have seen the entire sonic x series and I don't remember hearing that. The character Tails made his debut in October the 16th, in Sonic the Hedgehog 2 the video game.
Tails first appeared in Sonic the Hedgehog 2.
He is almost as fast as Sonic.
