He is an anthropomorphic echidna and the current guardian of the Master Emerald, a powerful ancient relic which is his solemn duty to protect from anyone who wants to abuse it. He is also the sole remaining descendant of the Knuckles Clan and last of the echidnas on earth.
A loner by nature, Knuckles is independent, headstrong and serious, yet gullible and short-tempered to a fault. He is fully devoted to his duty, spending most of his time on Angel Island protecting the Master Emerald, and rarely cares for anything that is not important. When his friends and others are in need of his help, however, Knuckles can always be relied on being willing to leave his post and prove himself a true and good-hearted hero. He is also one of Sonic's oldest friends and rivals.

- Punch Attack: Knuckles' triple punch combo.
- Drill Claw: A downward flaming attack at the foes.
- Deep Impact: Knuckles performs a punch which is so powerful that it causes friction with the air, creating a small explosion.
- Maximum Heat Knuckles Attack: Knuckles strikes his enemies with a high-speed homing attack after charging his power.
- Gliding Shock Wave Attack: Hyper Knuckles hits a surface while gliding, causing an earthquake that destroys everything within range.
- Ground Pound: Knuckles delivers a full-powered punch directly into the ground. The force from this blow creates rippling shockwaves of destruction which can send surrounding enemies like Stuffer Bot and Badniks flying
- Enerbeam: Knuckles can emit a tether made of several energy bolts intertwined to form a solid whip from the his wrist which can extend and contract when necessary. As a tool, the Enerbeam can latch onto targets to pull them in, lasso enemies, or let the user swing from point to point. Alternatively, it can be used as a make-shift rope. This makes the Enerbeam a versatile tool for both navigation and combat.
