Knuckles the Echidna (ナックルズ・ザ・エキドゥナ, Nakkuruzu za Ekiduna?) is a character that appears in the Sonic the Hedgehog series. He is an anthropomorphic echidna and the current guardian of the Master Emerald, a powerful ancient gemstone which is kept on Angel Island. Guarding it is his solemn duty to protect from anyone seeking to abuse it, as well as the sole surviving.

I've noticed that some people have trouble getting colors of the characters right (especially those with various vision problems), so I thought I'll help by giving you some color values. In that case his colours are complimentary. Knuckles and sonic both have striking eyes because they are anagolous.

The muzzle is standard peach color. The nose, as well as all representatives of his species, is small, but pointed black. He has a white crescent-shaped symbol on his chest.

Like all echidnas like him, he also has a large, long and curved tail. Knuckles is a character in the Sonic the Hedgehog series of video games, television shows and comics. Some of his nicknames include "Knuckie" (Rouge's pet name for him in the animated series Sonic X), "Rad Red", "Knux", and "Knucklehead".

His creator is Takashi Thomas Yuda. He is a red echidna, and while Sonic has quills, Knuckles has red dreadlocks. He is between 16 - 29 years old, 110 cm (3.
