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.

“Ugandan Knuckles” has its origins in a nearly year-old joke, but thanks to an easily downloadable character model and the explosive world of VRChat, the problematic meme has been quickly spreading.

Ugandan Knuckles didn’t start out as the Ugandan Knuckles meme; the character is inspired by a goofy caricature of the echidna, who first made his appearance in Sonic the Hedgehog 3. The weird version of Knuckles made his debut in a Sonic Lost World video review from Gregzilla, a popular YouTuber with more than 120,000 subscribers. Other YouTubers latched on to the character and started to create “Knuckles Sings” videos, a series of memes in which the deformed Knuckles sang a variety of songs, like Smash Mouth’s “All Star.”

It wasn’t until September 2017 that a 3D model of the deformed echidna entered the world, giving birth to memesters everywhere. Still, it would be another three months before players of VRChat — a Second Life-esque world that lets Oculus Rift and HTC Vive owners inhabit 3D models and interact with others in a variety of settings — latched on to the model, downloading it in hordes and inserting hundreds of strange Knuckles into the game. Using inspiration from the movie Who Killed Captain Alex, the meme was born. Some phrases a lot of people use include: 'YOU DO NOT KNOW THE WAY!' , 'WHY R U RUNNING?!' , 'THE QUEEN, WHERE HAS SHE GONE!!' , '*clicking noises*' ,
