Knuckles was a born climber, and you can see why! He uses his unique knuckles to climb walls, and a punch from him will leave you seeing stars for a month. He was born on the Floating Island and is the Guardian of the Chaos and Master Emeralds. At first, Dr. Robotnik had Knuckles convinced that Sonic and Tails were trying to steal the Master Emerald, when of course he was the villian. Today Knuckles and Sonic compete and argue, but their friendship is stronger than even they know.
