When Knuckles is in his Super State, he gains invincibility and all his powers and natural abilities are enhanced up to their full limit. Super Knuckles is several times faster and more powerful, and can climb walls twice as fast and fly. He, however, needs rings to maintain this transformation.

Knuckles is a playable newcomer in Super Smash Bros. for Nintendo Switch. Being one of the most requested characters for the series, he was added to the roster, and it was his inclusion where Sakurai and team decided to create a big roster for the game.

Sonic is Knuckles' good friend and rival. They have known each other for a long time, but their relationship seems to be somewhat complicated. The two do not understand their differences, Sonic being cool and cheeky and Knuckles being tough and serious. The two of them were initially enemies, due to Dr.

The transformation can only be obtained by collecting the seven Chaos Emeralds as Knuckles. The player can then activate Knuckles' Super State by collecting at least fifty Rings and then press the jump button twice in succession. While Knuckles is transformed, the player's Ring count drops by one Ring every second.
