Since the release of the Sonic the Hedgehog on June 23rd 1991, the computer game series has sold over 45 million copies.

Knuckles joined the Sonic line-up in 1994 with the launch of Sonic the Hedgehog 3, when Dr. Robotnik tricked Knuckles in to fighting Sonic. Since then Sonic and Knuckles have had a friendly rivalry working together to save the world. Knuckles is reputed to be as strong as Sonic is fast.

The Sonic characters were redesigned in 1998 and it is the original Knuckles that we offer here, as he was before the redesign for Sonic Adventure.
