Knuckles, the guardian of the Master Emerald, brings brute strength and unique traversal abilities to the team. He's a master of vertical and horizontal exploration, capable of scaling walls and gliding across long distances. His playstyle is about finding alternative routes and breaking through obstacles that other characters cannot.

Unique Abilities:
- Glide: While in the air, hold the jump button to glide horizontally for a significant distance. This is excellent for crossing large gaps or descending slowly.
- Wall Climb: While gliding into a vertical surface, Knuckles will cling to it. You can then press up to climb the wall, allowing him to reach high ledges and discover hidden areas.
Optimal Playstyle:
Knuckles is perfect for players who enjoy finding shortcuts, breaking through barriers, and exploring every nook and cranny of a level. His glide and wall climb allow him to access areas that are completely inaccessible to Sonic or Amy. He can also break certain destructible blocks with a powerful punch (often by gliding into them or using a Spin Attack). He's particularly useful for finding Big Rings and other collectibles hidden on vertical surfaces.
Synergistic Chaos Powers:
- Ivy: While Knuckles can climb, Ivy can provide an instant vertical boost, allowing him to reach even higher starting points for his glide or climb.
- Bullet: Can be used to quickly traverse long horizontal distances after a glide, or to break through multiple obstacles in a row.
- Vision: Helps him spot hidden breakable walls or secret passages that his unique traversal abilities can then exploit.
Knuckles is the ultimate explorer, offering a rewarding experience for players who like to deviate from the main path and uncover all the game's hidden content.
