Knuckles the Echidna

"As far back as I can remember, I've been living here on this dark island, always guarding the Master Emerald from anything that could harm it. I don't know why I was given this job, why it was my fate... destined to be here.. forever."

- Knuckles, Sonic Adventure

Knuckles the Echidna (ナックルズ・ザ・エキドゥナ Nakkuruzu za Ekiduna?) is a fictional character from the Sonic the Hedgehog series. He is an anthropomorphic echidna and the current guardian of the Master Emerald, a powerful ancient relic which is his solemn duty to protect from anyone seeking to abuse it. He is also the sole remaining descendant of the Knuckles Clan and last of the echidnas on Earth. His dominant traits are his superhuman strength, and the two spike-like knuckles on each of his hands, from which his name is derived from, which he can use to dig with and climb walls.

Why He's Tougher Than Leather

 * 1) A loner by nature, Knuckles is independent, headstrong and serious, yet gullible and short-tempered to a fault.
 * 2) He is entirely devoted to his duty, spending most of his time on Angel Island protecting the Master Emerald, and rarely cares for anything that is of no importance.
 * 3) When his friends and others are in need of his help, however, Knuckles can always be relied on being willing to leave his post and prove himself a faithful and good-hearted hero.
 * 4) He is also one of Sonic's oldest friends and rivals.
 * 5) Knuckles plenty of amazing, hip-hop/jazz stylized music In Sonic Adventure and Sonic Adventure 2, like Unknown from M.E (his main theme), Pumpkin Hill and Space Trip Steps.
 * 6) He spawned some internet memes, like the Ugandan Knuckles meme, and his famous line from Sonic Adventure: "Oh no."

Bad Qualities

 * 1) Knuckles is extremely gullible, often tricked by Dr. Eggman into believing that Sonic is the enemy, which is a great cause for many of their confrontations.
 * 2) It appears that he's been sleeping on the job, since he's hardly seen guarding the Master Emerald in the recent installments.
 * 3) He was flanderized in Sonic Boom, becoming from a gullible, yet lovable and smart hero, to a lazy dumb idiot, even getting a page on the Loathsome Characters wiki.

Trivia

 * According to the Sonic the Hedgehog 3 manual, Knuckles' favorite food is grapes. This is referenced many times through the series.
 * Despite this, Echidnas don’t eat grapes in real life, they actually eat ants and termites.
 * He was originally going to have a Jamaican accent, despite being based on an Australian creature, for example watch this video.
