Appearance and attire-wise, Knuckles looks exactly like his counterpart, the only outward difference between them being their mannerisms and speech. During his stay in the Sonic Boom World, he wore a blue party hat with spikes.


TV series


For a long time, Knuckles led his team to several victories against his arch-enemy Dr. Eggman.[1]

Season one

SB S1E35 Knuckles And...Knuckles

Knuckles in the Sonic Boom World.

During an assault from Eggman's Octopus Bot where Knuckles turned the battle in his team's favor, the robot shot a laser that sent Knuckles to a place with another version of his team, including a dimwitted version of himself. Accepting a hat to distinguish himself, Knuckles sought Dave the Intern's help, believing him to be a genius, though it was Tails who figured out Knuckles had been sent to another dimension. Realizing he needed Dr. Eggman's technology to get home, Knuckles recklessly charged Dr. Eggman's lair against his allies' wishes, only to get captured when he started flickering due to the paradox of having two Knuckles in one dimension. He was later rescued by Team Sonic who got him back home with Eggman's aid in time to help his Sonic and keep their dimensions from imploding.[1]


The polar opposite of his counterpart, Knuckles is described as smart, sophisticated, charming, likable and a born leader. Much more grammatically gifted than his counterpart, Knuckles speaks using a wide range of vocabulary and proverbs, the latter which several have noted makes him sound like a fortune cookie. However, he sometimes comes off as a know-it-all, such as when he formally noted Sonic's aggressiveness after he schooled him in pacifism (even though he forced Sonic to act as such).[1]

Knuckles is shown to be very modest, gladly wearing a silly hat to distinguish himself. He is impatient though, unlike his counterpart who likes to take his time, as he prefers to take action rather than wait around. He also shares his counterpart's brash attitude, invading Eggman's lair and smashing his badnik to get what he wants, an attitude that Sonic finds aggressive.[1]

Powers and abilities

SB S1E35 Knuckles super punch

Knuckles' ground pound.

Knuckles possesses the same physical strength as his counterpart, capable of creating destructive shockwaves which can send enemies flying by just punching the ground. However, Knuckles appears much stronger and disciplined in the usage of his strength, as he can not only direct his shockwaves, but also make them powerful enough to knock back hordes of Badniks and Octopus Bot at the same time.[1]

Along with his intelligence and charisma for leadership, Knuckles is a profound hand-to-hand combatant and has a flair for battle ingenuity, using hoverboards as projectiles with great accuracy.[1]


Sonic Boom World

Knuckles the Echidna

Two Knuckles One Bro

Knuckles with his counterpart.

Knuckles the Echidna is Knuckles' counterpart from the Sonic Boom World. Despite this Knuckles being the very opposite to his good behavior, Knuckles holds no ill will at him and enjoyed meeting him. He refers to him as his "dimwitted version."[1]

Sonic the Hedgehog

When meeting with the Sonic Boom World's Sonic, Knuckles did not agree with Sonic's passive leadership and would point out when he contradicted himself. By the end though, Knuckles had come to respect Sonic and praised him for his capabilities.[1]

Mirror Dimension

Sonic the Hedgehog

Knuckles has great patience for his Sonic's clumsiness and treats him with kindness and support akin to what a parent or older brother would show to a child. He refers to himself as a "grown-up" when taking to Sonic.[1]

Amy Rose

SB S1E35 I knew you fall for me

Knuckles after saving Amy.

Knuckles acts very chivalrous towards his Amy, taking to her with respect and being there to save her when in need, while kindly teasing her romantic feelings for him. Whether he feels the same way for her is unknown.[1]

Dave the Intern

Knuckles has great respect his world's Dave the Intern's intellect, believing he alone could explain how he ended up in the Sonic Boom World, and refers to him as his friend.[1]


"Worry not, young Tails. Be diligent. In time, the answer will seek you."

"Now, if you'll excuse me, the grown-ups have some work to do."
