Knuckles

Knuckles the Echidna, commonly known simply as Knuckles, is a red echidna from the  franchise and is the guardian of the Master Emerald on Angel Island. In the Mario & Sonic Olympics crossover installment series, he competes against Mario and others in Olympic style events in which he acts as a Power type character (meaning he excels at games that require brute strength, such as Hammer Throw or Javelin Throw). He is also the fastest of the Power characters. In Mario & Sonic at the Olympic Games, he was voiced by Dan Green, who also voiced Vector in that game. He was voiced by Travis Willingham from Sonic Free Riders up until Team Sonic Racing, where he is instead voiced by Dave Mitchell.

After completing the Luge mission, Cream will give the Fighter's Stick to Knuckles. Later at Cubyrinth, the team come across a lever that is too rusty to pull. After Knuckles pushes the lever, the floor falls and everyone falls down to Polastraits. After realizing where they are, they come across a large wall of ice. Not wanting to swim, Knuckles punches the large wall of ice in 45 seconds.

Mario & Sonic at the London 2012 Olympic Games
Knuckles returns as a Power-type character in the Wii version of Mario & Sonic at the London 2012 Olympic Games, where he appears in the opening with all of the other athletes and competing in Canoe Sprint 1000m and Football. A Mii outfit based on Knuckles can be unlocked, and he also appears as a character that can be spoken to in London Party mode in order to play minigames and earn stickers.

In the Nintendo 3DS version, Knuckles is included in the Wild Ones group, meaning that he is only playable in certain Events. In the Story Mode, Knuckles first appears with Vector chasing Bowser at Horse Guards Parade, and challenges him when Sonic shows up. When he and Vector win, Knuckles destroys the fog machine and clears the Phantasmal Fog form the area on Sonic's request, and then stays behind with Vector to interrogate Bowser, though it later turns out to be a hologram of him. Knuckles also calls Mario, Luigi, Sonic and Tails when they face Bowser and Dr. Eggman to support them and tell then that they have cleared the fog from Horse Guards Parade, and later appears at the opening ceremony. Knuckles also appears in the bonus episode The Life of a Minion, where he and Vector are tricked into competing in a match with Bowser, which they end up losing. A badge of Knuckles can also be obtained from the badge machine.

Profile
"Knuckles is an echidna that shows exceptional versatility despite his overall strength in Power events. He'll perform best at events like throwing and rowing, but can also provide solid competition in many other competitions that aren't as power-based."

Profile
"Knuckles the Echidna has been friend and foe to Sonic for years. He has protected the Master Emerald on Angel Island, but now has his eye on a new prize: being #1 in the Olympic Winter Games! Powerful and determined, Knuckles will be going for gold with his Screw Driver ability on the Wii and DS, and Spiral Uppercut ability on the DS."
