Welcome to Sonic Saturdays! This is the part of the site
Knuckles was created as a new rival for Sonic during the development of Sonic The Hedgehog 3 for 1994. He was originally tricked into fighting with Sonic by Dr.Robotnik, AKA Dr. Eggman, who told Knuckles that Sonic was an invader of his floating, Angel Island.
Sonic The Hedgehog 3′s events happen immediately after Sonic 2. After defeating the Egg Robo and coming down from Space as Super Sonic, with Tails in his bi-Plane, you Land on the Floating Island. Knuckles is strong enough that with one punch, he knocks Super Sonic back down to regular Sonic and steal his Chaos Emeralds.
Dr. Robotnik has tricked Knuckles into thinking that Sonic And Tails are after the Master Emerald. This is why Knuckles attacks them. The Master Emerald is what keeps Angel Island afloat, and Knuckles is the last Guardian of said Emerald.
Sega, and Archie both have his personality as a Seriously minded, tough guy loner who is easily tricked, that can be violent if you make him mad. Although he and Sonic fight from time to time, there is an undercurrent of mutual understanding between the two. Sega typically makes him the Power Character.
In the Genesis titles Knuckles is Almost as fast as Sonic, but has some powers of his own. He’s able to climb walls by punching them, he can glide, and get to many areas that Sonic can’t. Also when you connect Sonic & Knuckles to Sonic 3, Knuckles has a Super form commonly referred to as Hyper Knuckles.
Knuckles’ Chaotix was released for the failed Sega 32x in 1995. It was the only Sonic game put out on the system, and introduced us to some friends that were used in later titles. This game takes place on Carnival Island. A new, Mysterious island that had raised after what happened in Sonic & Knuckles. This was also the second and last appearance (so far) of Mighty The Armadillo.
In 1999, For Sonic Adventure, a mysterious creature is born from within The Master Emerald, known as Chaos. As he appears the emerald is shattered, which causes Angel Island to fall into the ocean. It’s Knuckles’ responsibility to reforge The Master Emerald and restore his home.Sonic Adventure also deals with Knux’s ancestors, and the meaning behind the Chaos Emeralds and The Master Emerald. In Sonic Adventure 2 it is Knuckles who shatters it to prevent Eggman from stealing it. He then finds a rival in Rouge the Bat, as she is after the pieces of the emerald too.
If you haven’t guessed by now, this part of the Knuckles Spotlight is the Sega Cannon, Part 2 will be the Archie Cannon. I know Sonic Chronicles: The Dark Brotherhood has a rather large significance to Knuckles, but alas I haven’t played it. Although I hear it has something to do with a rivalry between Knuckles’ Ancestors and another clan of echidnas known as The Nocturnus Clan.
That’s it for Part 1, be sure to check out next week when I try to tackle the convoluted history or the Archie Comics version of Rad Red.
