Knuckles the Echidna 

One of the main characters of Sonic the Hedgehog franchise. He's really cool, stoic, badass, friendly, ass-kicking and a true hero. Knuckles shares many similarities to Piccolo from DBZ. Both are loners who don't talk much but are honest, they are both heroes who were villains when they first appeared, but turned good. They both have a friendly rivalry with the protagonist (Sonic and Goku, who are also very similar) and also became good friends with a cheerful kid (Tails and Gohan). Both protect their homeland which means everything to them.

Another character similar to Knuckles is Gaara from Naruto. They were both villains by for a very short time but became heroes afterwards. Both are very good friends and former rivals of the protagonist (Sonic and Naruto). They are also both red headed.

Knuckles the Echidna is ultra badass

Knuckles The Echidna 

Knuckles is a cool guy with a bad attitude. He does'nt like to be pushed around. Him and Sonic fight a lot, but I think their good buddies.

Knuckles is cool.

Knuckles The Echidna 

Knuckles the echidna is one tough dude. Always protecting the Master Emerald from anything/anyone that could take it. He's a loner, he's gullible, and very shy around certain girls. He's the only reason that you should be playing any Sonic The Hedegehog games. He's also got good manners, but when he's around Rouge the bat, he changes all that (even though Knuckles secretly loves Rouge) because he knows that she's after the Master Emerald.

Knuckles The Echidna and Rouge The Bat do belong together, they're just meant together know what I mean? Anyway, Knuckles really is the best out of all the Sonic characters. I LUV KNUCKLES!

Echino Scale 

The Echino scale assigns a single number to quantify the amount of gayness in an individual or event.

The Machine was clearly a 8.5 on the Echino scale. I haven't seen that many chaps since the gay pride parade.

Knuckles the echidna 

A character from Sonic the hedgehog. Knuckles is the soul survivor of an ancient echidna tribe,who were whiped out by Chaos, the god of destrucion. He lives on Angel island, guarding the master emerald, he's as strong as he is gullible and he is the strongest sonic character AND HE DOES NOT LOVE ROUGE THE BAT!!!! (You could say that he absolutely DESPISES her for trying to steal the master emerald)

He's also the 3rd fastest sonic character
