Sonic the Hedgehog 3 & Knuckles
Super Knuckles in
. Sonic & Knuckles
Super Knuckles first appeared in
and its extension Sonic & Knuckles . The transformation can only be obtained by collecting the seven Sonic the Hedgehog 3 & Knuckles Chaos Emeralds as Knuckles. The player can then activate Knuckles' Super State by collecting fifty Rings and then press the jump button twice. While Knuckles is transformed, the player's Ring count drops by one Ring every second. When the Ring count hits zero or when the Act Boss is defeated, the transformation runs out.

invincible, can move, glide and climb faster, and jump higher. In Sonic the Hedgehog 3 & Knuckles, should the player enter the neon flashing giant ring in Mushroom Hill Zone, the player will have their Chaos Emeralds turned into Super Emeralds in Hidden Palace Zone, thus preventing Knuckles from becoming Super Knuckles anymore.

Power Cores. Unique to Super Knuckles, his Volcanic Dunk attack has been changed, enabling him to throw fireballs in front of him over a long range to attack targets. During the boss battle, the player's Ring count drops by one every second, and when it runs out, Knuckles and his team revert back to normal which will cost the player a life.

Sonic the Hedgehog 3 & Knuckles

Sonic the Hedgehog 3 & Knuckles. Like before, the player's Ring count drops by one for every second Super Knuckles is active. When it reaches zero, Knuckles reverts back to normal.
Powers and abilities
Due to being infused with the seven
Chaos Emeralds' power, Super Knuckles accordingly commands ultimate power and has access to unlimited energy.  As Super Knuckles, Knuckles' innate abilities far surpasses his normal ones. His trademark strength has been enhanced to the point where he can smash a ship from the  Eggman Fleet with a single strike and throw punches so powerful that he creates fireballs which explode upon impact. Knuckles also becomes fast enough to keep up with even Super Sonic who can move at approximately the speed of light.  His reflexes are also improved, allowing him to keep up with his increased movements. Like the traditional Super State, Knuckles gains new abilities in this form, including high-speed run-flight and virtual invulnerability to harm.
All of Super Knuckles' standard techniques has been greatly enhanced following his transformation; his
Volcanic Dunk technique has been upgraded to the point where he can shoot a barrage of explosive fireballs at his foes, and Glide and Climb techniques can be executed on a much faster rate.
Super Knuckles can only stay transformed for a short time without sustainment from
Ring Energy, as a Super State consumes tremendous amounts of energy. Extensive usage will also put him at risk of disappearing entirely.
In other media
Super Knuckles in the Archie Comics.
comic series and its spin-offs published by Sonic the Hedgehog Archie Comics, Knuckles' Super State was dubbed "Hyper Knuckles." This was because he was set up to battle Super Sonic, and the writers wanted to avoid the monotony of two supers against each other. [ However, this form would be referred to as "Super Knuckles" later on.

Super Sonic in a battle for the Chaos Emeralds. Knuckles later turned into Hyper Knuckles again to battle Master Mogul alongside Super Sonic and Turbo Tails. Knuckles later obtained his super form again to fight Hunter on Angel Island, this time using the power of the Master Emerald.
Man, he's tough!" —Super Knuckles getting fazed by Metal Overlord's nigh-invulnerability.
