Echidnas

Echidnas (ハリモグラ科, Harimogura-ka) are a species that appears in the video game, comic book and television series, but most of all, the Sonic series. Unlike the real-life species, foxes in the Sonic Universe are anthropomorphic, dreadlocked animals of said species, with long quills hanging from around their head which stand out from the other humanoid animals, and the most recognized of them being Knuckles the Echidna. Several robotic copies of hedgehogs also exists, most of whom were created by Dr. Eggman in imitation of Sonic, the most famous of them being Metal Knuckles.

In every which the location exists, the most echidnas are the native inhabitants of Angel Island or their original homeland, the hidden island of Albion.
