Okay, time to yap.
One of the ending themes to Sonic X, Hikaru Michi, was sung by Aya Hiroshige when she was 10 years old. It was her debut.
Speaking of Sonic X, the Sonic movies spiked just enough popularity in Japan to allow the finale to air in Japan- in Japanese. I'm serious.
One of the composers for Sonic CD, Naofumi Hataya, said if that he were to write a book about how much he loved the soundtrack, it would be over 2,000 pages long.
More of a misconception, but Maurice was not a Ken Penders trademark.
Speaking of Ken Penders, the following characters are not created by him: Monkey Khan, Rosemary Prower, Mammoth Mogul, Mina Mongoose, Zonic the Zone Cop.
In very early canon, Tails taught Sonic how to spin-dash.
Sonic used to ride with dolphins from time to time.
One of Sonic's concepts pitched to SEGA in New York while the 1989 (or 1990) mascot contest was going on was a parakeet. It ended up becoming Sharps the Parakeet.
Sonic Underground was supposed to have an Archie adaptation for Sonic Universe #50, but was replaced with Worlds Collide- to weave into the reboot.
And finally... Knuckles used to be a hedgehog. Then a mole. Then he got turned into an Echidna named Stealth. Yeesh, real good development there.
(why did the original #7 sound so much better in my head)
