Knuckles, the guardian of the Master Emerald, brings a different set of skills to the table. While not as fast as Sonic, his strength and unique movement options open up entirely new pathways. Knuckles can Glide by pressing and holding the jump button while in the air. This allows him to traverse long distances, cross large gaps, and even reach higher platforms that Sonic cannot. While gliding, he can also climb walls by pressing against them, enabling him to scale vertical surfaces. His attack is a powerful punch, which he performs by pressing the jump button again while gliding. Knuckles' levels often feature more vertical exploration and hidden areas accessible only through his gliding and climbing abilities.
