Knuckles

"Knock Knock, It's Knuckles!"

Knuckles is a protagonist in Sega's Sonic the Hedgehog franchise, making his debut appearance as an antagonist in 1994's Sonic the Hedgehog 3 and becoming an ally in Sonic & Knuckles.

He is also a playable character in Nexed.

Real-World History
During the development of Sonic the Hedgehog 3, the development team sought to create a character that would rival Sonic (as opposed to Dr. Robotnik's role as a full-on antagonist). After dozens of concept designs were pitched (including a reptilian design inspired by the popularity of the Jurassic Park franchise), Knuckles' final design was designed by Takashi Yuda.

Yuda had designed Knuckles as an "intimidator" due to his incredible strength. Many aspects of the character's design were inspired by studies conducted on American youth, which led to Knuckles' dreadlock hairstyle and red coloring (while Yuji Naka had originally pushed for the new character to be purple). He was initially meant to speak with a Jamaican accent.

Upon his debut in 1994, Knuckles became a wildly popular character, making his playable debut in Sonic & Knuckles that same year and gaining his own self-titled game in the form of Knuckles' Chaotix in 1995. In 1999, Knuckles, alongside many other Sonic characters, was redesigned for the release of Sonic Adventure, which would become the definitive look for Knuckles going forward.

Knuckles is recognized as a major player in the Sonic the Hedgehog franchise, appearing in various games, comics, films, and other media based on the franchise. He has also become the subject of numerous internet memes, most notably "Ugandan Knuckles" in 2017.

Gameplay Information
"The last of his kind and the guardian of the Master Emerald, Knuckles the Echidna is hot-blooded and no-nonsense. He’ll break down any threat to Angel Island, whether it be solid or frail, and while he may have started off as a rival to Sonic, he has since become one of the Blue Blur’s closest allies.

Knuckles’ claim to fame is his brute strength and fighting skill, which he has honed over the course of his duty. However, seeking more answers of his heritage, he set off to the tournament with the hopes of using the Winner’s Wish to discover the truth of the Echidna tribe… After leaving the Master Emerald in safe hands, of course."

Knuckles is a character with great potential for dishing out damage. He has solid combo potential and a number of heavy-hitting attacks, some of which can get KOs fairly early on. In addition, his horizontal recovery is one of the best in the game distance-wise, making it easy for Knuckles to recover from above the stage. Overall, Knuckles is a character who excels in grounded combat due to his hard-hitting moves and combo potential.

However, due to this, Knuckles suffers with aerial combat, having weak aerial attacks and a poor vertical recovery. In addition, Knuckles is slower than his build suggests; While he isn't as slow as a heavyweight, his speed and jump height are less than desirable. While Knuckles isn't completely helpless in the air, players should strive to focus on attacking on the ground, using Knuckles' Side Special as their main recovery option.
