The Sonic series is well known for its interesting characters, and Knuckles is deffinetly one of em!

Sonic's first rival debuted in Sonic the Hedgehog 3. Dr. Eggman fooled Knuckles into believing that Sonic and Tails were invading Angel Island to steal the Master Emerald. In the end, Eggman revealed his true intentions and Knux joined the hedgehog and fox.

Knuckles is well known for both his appearence and abilities. In real life, echidnas look a lot like hedgehogs, but Knuckles looks nothing like Sonic. He is red with long dreadlocks and spiked gloves. His abilities include gliding, digging, knowledge of martial arts, and power over the Master Emerald which he protects.

The personality of Rad Red changes constantly. Knuckles is somewhat gullible and has been tricked by Eggman on many occassion. He can also be quick to anger, depending on the circumstances. Fans try to look past this, knowing there is more to Knuckles than brute force. In the Sonic Adventure series he was calm and very likeable. However, ever since 4Kids took over and Dan Green began voicing the character, Knuckles has been nothing but these flaws ruining him. Other than Sonic himself, Knuckles is my favorite character and shame on 4Kids for ruining a great character!

In the near future, I hope Sonic Team will develop on Knuckles. He's the last of his kind and it would be great to know more about his past.
