— Knuckles the Echidna, Sonic the Hedgehog #12

Knuckles the Echidna is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. He is an anthropomorphic echidna, a friendly rival of Sonic the Hedgehog, and the sole guardian of Angel Island and the Master Emerald. He is also the former commander of the Resistance.[3][4]



Knuckles' full profile, from Sonic the Hedgehog #3.

Knuckles is an anthropomorphic echidna with red fur that covers most of his body, peach skin on his muzzle, a white crescent-shaped patch of fur on his chest, and purple eyes. He also has seven dreadlock-like spines on his head and a medium-sized tail.

For attire, Knuckles wears red and yellow shoes, each with green cuffs and a grey, sextuple-bolted plate on top. He also wears white, mitten-like gloves with sock-like cuffs and two spiked knuckles on each hand. Both his gloves are quite large.



Some time ago, Knuckles participated in a situation involving the Space Colony ARK in which Eggman used its Eclipse Cannon to blow up a part of the moon in order to show the world the power that he wielded. These events lead to Knuckles, Sonic the Hedgehog, and Miles "Tails" Prower teaming up with Rouge the Bat, Shadow the Hedgehog, and Eggman in order to fight a bigger threat.[5][6]

Later, Knuckles, Sonic and Tails formed a team. Soon after, a battle happened between Team Sonic and Neo Metal Sonic - the powered up form of Metal Sonic - who was impersonating Eggman. This time, the fake Eggman was piloting the Egg Emperor mech, but Knuckles and his friends defeated the mech.[7][8] After learning that Neo Metal Sonic had taken over the Eggman Empire however, Knuckles and his team defeated the robot, causing him to revert back to normal.[8]

The War

In the recent past, after Sonic got captured by Dr. Eggman, who was able to seize control over most of the world in doing so, Knuckles became the commander of a resistance group that opposed Eggman's reign (although it was Amy who kept the group organized).[3] Later on, after being reunited with Sonic, he, alongside the rest of the Resistance, defeated Dr. Eggman, thus ending the Eggman Empire's reign over the world.[7]

After the war, Knuckles and the Resistance set out to clean up from the war. However, with the Eggman Empire's Badniks being everywhere and randomly attacking anyone they came across, Knuckles and the Resistance had to work from a centralized, organized position that would allow them to combat the Badniks more effectively.[3]

Eventually, Knuckles went to investigate Barricade Town, but did not report back after a while.[3] While there, he single-handedly destroyed the Badnik horde that was surrounding said town. After finishing off a Death Egg Robot sentinel, Sonic came by on Amy's request to check up on him. Knuckles explained that Barricade Town's Wispon shipments had dwindled and that he came by to find out why. He and Sonic entered the town, finding the citizens in a panic. There, they were informed by the gatekeeper that their town's Wispons had been stolen by a duo of mercenaries that had, before the war ended, driven Eggman's forces away and saved Barricade Town, only to then conquer the town and keep its arsenal to themselves. Knuckles and Sonic went off to the town's supply depot-turned-fortress to put an end to the mercenaries' cruelty. There they found several Wisps being horded. Soon, Knuckles and Sonic confronted the mercenaries, who introduced themselves as Rough and Tumble. A battle ensued between the four that seemed to be evenly matched, until Sonic called upon the help of the Wisps who remained in the horded Wispons. After the Wisps broke out of the Wispons, Knuckles and Sonic easily defeated the mercenaries. Rough and Tumble were then taken to jail while Knuckles and Sonic celebrated their victory with the townspeople and Wisps.[1]

The Fate of Dr. Eggman


Knuckles sensing the Master Emerald calling out to him, from Sonic the Hedgehog #8.

Meeting with Sonic, Tails and Amy in Resistance HQ, Knuckles learned from Sonic that Neo Metal Sonic was the ringleader behind the recent organized Badnik attacks. Apparently, he had taken over the Eggman Empire in Eggman's absence in an attempt to continue Eggman's rule for him and give him back command after finding him. In an effort to undermine Neo Metal Sonic's scheme, Knuckles and Amy decided to help Sonic and Tails search for any old plans that could tell them what Neo Metal Sonic was up to.[8]

Continuing his work from Resistance HQ with Amy, Knuckles eventually sensed that the Master Emerald was calling out to him. Immediately after, Knuckles and Amy were contacted by Sonic and Silver, who, after having discovered Neo Metal Sonic's plan, told them to call in everyone.[2]

Battle For Angel Island


Knuckles vents his frustrations, from Sonic the Hedgehog #9.

After having called their allies to Resistance HQ, it was revealed to the assembled heroes that Neo Metal Sonic had taken over Angel Island and turned it into a flying fortress. To make matters worse, Neo had also secured the Master Emerald for himself on the island. Outraged at what had been done to his homeland in his absence, an upset Knuckles blamed himself for this. Knuckles was thus eager to volunteer for the team that would confront Neo Metal Sonic and secure the Master Emerald. Also, when Tails tried to discourage Blaze from going after Neo Metal Sonic as Burning Blaze, Knuckles told him that the Master Emerald could not interfere with the Sol Emeralds (the source of Burning Blaze's power). In the end, Knuckles and Sonic were chosen to confront Neo Metal Sonic and secure the Master Emerald while the others focused on breaking the Egg Fleet's control over the island.[9]

On the way to Angel Island, Knuckles refused to relax while his home needed him. When they finally neared Angel Island however, the Egg Fleet began bombarding their ship. Using their Extreme Gears, Knuckles and Sonic left the crashing ship and flew to the Master Emerald's shrine, which had been turned into a fortification. Inside it, the two heroes found Neo Metal Sonic on top of the Master Emerald. When they tried to confront him however, Neo Metal Sonic used the Master Emerald to turn into Super Neo Metal Sonic.[9]

With Knuckles understandably frustrated by this development, Super Neo Metal Sonic went on the offensive. Knuckles subsequently tried to reach the Master Emerald while Sonic distracted Super Neo Metal Sonic, but both him and Sonic were foiled and outfought at every turn by the robot. When Knuckles and Sonic ended up lying in defeat before Super Neo Metal Sonic however, Shadow showed out and succeeded in making Super Neo Metal Sonic revert back to normal before laying the smackdown on him. After Sonic brought the fight to a halt, Knuckles tried to get to the Master Emerald. However, Neo Metal Sonic then revealed that he had already copied Shadow's bio-data, which, combined with Sonic's bio-data and the Master Emerald's power, would let him assume his final form. As Neo Metal Sonic grew in power, Knuckles tried in vain to stop him. However, Knuckles was forced to evacuate the stronghold along with Sonic and Shadow once the structure started to fold into Neo Metal Sonic. The ground soon after began to rumble and Knuckles noted that the Master Emerald had been cut off from Angel Island―without its power, the island would fall. Meanwhile, Neo Metal Sonic grew into a form more monstrous than the last―dubbing it Master Overlord―and demanded that Sonic bowed to him.[10]


Knuckles brings the Master Emerald back to Angel Island, from Sonic the Hedgehog #11.

Getting attacked by Master Overlord, Knuckles contacted his allies in hopes of getting Burning Blaze's help, only to learn that it was not possible. He, Sonic and Shadow were then grabbed and flown away by Master Overlord, who wanted them to see him destroy their allies, who were onboard one of the Egg Fleet's battleships. It was then that Sonic came up with a plan: if they could drive Master Overlord closer to Angel Island and rip the Master Emerald out of him, they could deprive the robot of his power source and save the island. When the trio finally escaped Master Overlord's grasp, Knuckles relayed Sonic's plan to their allies while he tried removing the Master Emerald. Despite the hardships, Master Overlord was distracted long enough by Knuckles' allies for him to retrieve the Master Emerald and return it to Angel Island before the island plummeted into the ocean. In the aftermath, Sonic and Tails joined Knuckles at his shrine and informed the echidna that Metal Sonic was offline.[11]

While Knuckles rested on top of the Master Emerald, Sonic came to him and informed him that the island was intact. Sonic then asked if he was coming back to Resistance HQ, but Knuckles told him that was staying to guard the Master Emerald like he always had. As Sonic then reminded him of his responsibilities as the Resistance's commander, Knuckles decided to disband the Resistance as he believed there was no need for them anymore. He also dismissed Sonic's offer to stay in contact should he become lonely as he believed Sonic would only bring trouble. Knuckles soon saw his allies off as they left Angel Island in the repaired Egg Fleet battleship.[4]


Knuckles is a tough, wild, egotistical, and headstrong echidna. Serious and stubborn, Knuckles has no patience for stationary work, like paperwork, and prefers to be where the action is. However, he is an overall nice guy in normal conversations.[1]

Knuckles is fiercely loyal to his homeland and prefers to stay there.[1] As such, when anything bad befalls the island and its Master Emerald, Knuckles takes it very personally and blames himself for not being able to prevent it. He will also not rest or take it easy until he is sure that his island and its treasure are safe once more.[9] Despite his ties to his home however, Knuckles is very heroic and is willing to leave his duty whenever his help is needed. When not performing his duties, Knuckles prefers spending his time going treasure hunting.[1]

Knuckles is somewhat gruff and has an equally short temper. Combined with his heroic morals, he is quick to anger when witnessing villains' despicable behavior. However, he is not the sharpest tool in the shed and will willingly jump into a fight without thinking once about the consequences. Regardless, he is very strong-willed and will not give up on his goals once he has set them.[1]

Powers and abilities

Knuckles possesses incredible strength, being as strong as Sonic is fast; with a single punch, he is able to pierce thick metal with ease.[9] By stretching his arms and legs outwards while airborne, Knuckles can catch the air under his dreadlocks to ride on air, allowing him to glide through mid-air. Also, by using the spikes on his fists, Knuckles can deal extra damage to his targets and scale any kind of surface with ease. He is also a great hand-to-hand combatant.[1][11]

Being the guardian of the Master Emerald, Knuckles possesses a special link to the massive gem. As such, he can sense both the Master Emerald's energies and its will.[2][9]

Sonic and Knuckles Mocking Rough and Tumble

Sonic and Knuckles mock Rough and Tumble, from Sonic the Hedgehog #3.

Sonic the Hedgehog is both a close friend and rival to Knuckles, with the two of them being no stranger to butting heads over a disagreement at worst, or partaking in banter with each other at best. Due to their rivalry, they tend to occasionally try and outdo each other.[10] Despite this, the two put a lot of trust in one another's abilities and work near perfectly to get the job done.[1]
