Sonic the Hedgehog[]

Knuckles and Sonic, from Sonic Adventure.
Sonic the Hedgehog is Knuckles' rival and best friend.[12] While they have known each other for a long time, their relationship is somewhat complicated, the two of them having been summed up as "best frenemies."[13] When the echidna first met the hedgehog, the two had the worst kind of encounter,[14] with the former trying to keep the latter from stopping the Death Egg's re-launch after Dr. Robotnik had deceived him into thinking that Sonic was a thief seeking the Master Emerald. As such, they started off as adversaries. However, when Knuckles discovered that the doctor had tricked him, he joined forces with the hedgehog to stop his nemesis. Afterward, they parted ways on good terms.
Because of their first impressions of each other and their personalities and competing feelings, Knuckles and Sonic were not initially "good friends" to begin with.[14][10] In fact, they are much like oil and water. While the echidna exemplifies the mountain and is stern, serious, and unmovable, the hedgehog exemplifies the wind and is laid-back, cool, and free.[14][6] As such, they tend to argue a lot. They likewise share a competitive rivalry with each other and it usually comes to blows when they clash, although their confrontations have become less serious in recent times, and are now more of a form of slapstick between the two.[14] In fact, the more they fight, the better they get along.[15] With Knuckles' strength matching Sonic's speed perfectly, their battles are anything from climactic to just plain funny.
Knuckles sees himself as Sonic's rival, though it has been implied (and later stated by Knuckles himself) that it is because he envies the hedgehog's free lifestyle and self-reliant nature.[16] focusing on hand-to-hand combat, Knuckles makes use of his powerful fists to take on his foes, with his specialty lying in punching moves where he uses his spiked fists for devastating blows. In terms of fighting style, Knuckles focuses on power, using straight, repetitive and forceful punches, such as power-packed jabs or piercing uppercuts to deal critical blows to his opponents. For stronger strikes, Knuckles tends to build up momentum with his fists by swinging them around, before hitting his opponent in full force. By taking advantage of his burrowing abilities, Knuckles can even hide underground before hitting opponents with an uppercut from below when his opponent least expects it. Despite being a powerhouse, however, most of Knuckles' fighting moves are slow and easy to read.[17][6] Being as egotistical as he is as well, the echidna sees himself as Sonic's better, as seen during the Lost Hex incident where he claimed more than once that he could do better than his friend on his adventure. Also, because of his short temper, Knuckles usually falls for the hedgehog's teasing and provocations directed at him, which causes him to lose his cool and get angry at him.[18] This tends to make him seek outright brawls with Sonic to put him in his place,[14] and not wanting to talk about him at all.[18] The hedgehog also manages to find a way to get Knuckles involved in his skirmishes very often, which the echidna finds very annoying. Nevertheless, he is willing to admit that one rarely gets bored with Sonic.[19]
Due to his lack of social abilities in the past, Knuckles used to fall for the deceit of Dr. Robotnik, later known as "Eggman", very often, which, in turn, would be the cause of most of his confrontations with Sonic, although as time passed, he has generally become more aware of the doctor's plans and has stopped believing his claims regarding the hedgehog. When the echidna discovers he has been deceived by Eggman though, he usually tries to hide his embarrassment from Sonic,[20] who in turn tends to chide him by calling him "Knucklehead", a nickname that does not sit well with Knuckles.[21]
In contrast to their differences, after having been on several adventures together, Knuckles and Sonic's relationship has improved, with the former seeing him more and more as his friend. Likewise, they have always rushed to each other's aid when they are in a pinch.[14] The two of them are connected by a hot-blooded friendship[22] and while they still argue and complain about each other from time to time, they are perfectly synchronized in the heat of action.[14] Details aside, they also have a connection that lets them understand what is really important without saying anything to each other. In fact, when it all comes down to it, Knuckles can be considered Sonic's best friend next to Tails. It can even be argued that the two of them are as close to each other as Sonic and Tails are, as the nature of their rivalry/quarreling friendship lets them have a relationship that does not require any hesitation.[14] Also, according to Tails, Sonic and Knuckles are "funny" together.[23]

While Knuckles is impressed by Sonic's skills on some level, respects him, and believes him to be a "good guy" and his friend,[24][6][10] he prefers not to admit it when he needs his help; as seen during the Time Eater incident, after the hedgehog restored the echidna from a lifeless state, the latter thanked him for his help before quickly stating that he did not need it.[25] At the end of the same incident, Knuckles also begrudgingly admitted that Sonic was not "half-bad" after defeating the Time Eater, showcasing a reluctance to admit how well Sonic does. Despite it all though, the echidna and the hedgehog deeply acknowledge each other.[22] The two are also great and loyal teammates. In addition to Knuckles being a vital part of Sonic's team, the two of them have been called "Fighting Buddies" on one occasion. Noticeably, when they do manage to work together, they form an unstoppable team. Additionally, the echidna is always happy to help out the hedgehog if it means scrambling Eggman's plans for world domination.[26]
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.[27]
Knuckles' seriousness often contrasts Sonic's carefreeness, but that does not stop them from being a tight-knit team in a fight. Furthermore, the two of them put a lot of trust in one another's abilities and work near perfectly to get the job done.[28] Knuckles in particular holds a high opinion about Sonic's ability to resolve any crisis, but also blames him for bringing trouble to his island every time they meet, yet presumably still forgives him and hides this fact from him out of embarrassment.[29][30]
Miles "Tails" Prower[]

Knuckles and Tails, from Sonic Heroes.
Miles "Tails" Prower is a close friend of Knuckles. Although they do not seem to have much of a relationship in the earlier games, when they first met, Knuckles and Tails were enemies, as Dr. Robotnik had tricked the echidna into believing Tails and Sonic were intruders seeking the Master Emerald for evil purposes, though they become friends when Knuckles discovers that Robotnik had lied to him.
Knuckles shows a more amicable attitude towards Tails, particularly compared to his interactions with Sonic and others, although the fox may occasionally irritate the echidna with his technobabble.[31] Additionally, by the time of Starfall Islands incident, Tails' manners had begun to imitate Sonic's due to having spent so much time with him, much to Knuckles' displeasure.[18] However, the echidna seems to enjoy teasing his friend from time to time, such as when he scared him with the idea that Team Sonic had fought with Shadow's ghost just before entering Hang Castle during the Neo Metal Sonic incident.[32] Nevertheless, the echidna does care about Tails, attempting (with little success) to defend him from Wave's taunts during the first EX World Grand Prix.[33]
Amy Rose[]

Amy Rose has only been seen interacting with Knuckles on very rare occasions, although they seem to have an awkward, yet at the same time, friendly relationship. During the War to Take Back the Planet, they were teammates as part of the Resistance. Although they got along well, Amy had to keep Knuckles in check at times. Amy also knocked Knuckles into a tree at the end of the Time Eater incident when talking about how good both Sonics did at stopping both Eggman. Despite them not always in agreement, Amy does care about him and his well being.

Amy Rose is a good friend of Knuckles, as the two having known each other for a long time. They both played vital roles in the Resistance during the War to Take Back the Planet, with Knuckles as the commander and Amy as the lead organizer.[34] When Neo Metal Sonic took over Angel Island, Amy was quick to show concern and comfort Knuckles during his fit of anger, assuring him that she and the others would help him liberate the island.[35][36] When Amy later visited Angel Island to return a relic that she found in the possession of Rouge, Knuckles was extremely grateful and offered Amy to join him in returning the relic to its proper location, much to her excitement.[37]
Amy has a high level of respect for Knuckles' strong commitment to his duty, understanding that a location as precious as Angel Island should be protected, and is shown being impressed at the ease with which Knuckles navigates the island.[37]
Dr. Eggman[]

Knuckles being deceived by Dr. Robotnik, from Sonic Adventure DX: Director's Cut.
Dr. Eggman is Knuckles' worst enemy. They first met during the Angel Island incident, where the doctor, at the time carrying the name "Dr. Robotnik", tricked the echidna into believing that Sonic and Tails were thieves trying to steal the Chaos Emeralds. At the last second, however, after Eggman betrayed Knuckles in Hidden Palace Zone Knuckles could see through the villain's lie and joined the hedgehog's side to stop him. In the later crises that arose though, the echidna, due to his gullible nature, was still occasionally manipulated by the scientist in his favor such as in Chaos incident and Super Eggrobo Z incident, which made him feel very embarrassed when Sonic found out about it.
More recently, Knuckles has shown a very hostile and rough attitude towards Eggman and is more wary of his deceit; during the MeteorTech incident, he had a complete refusal at first to believe any words that came from the doctor's mouth concerning the global MeteorTech rampage. Soon after, he was even willing to physically threaten Eggman to extract information or when he seemed to have sprung a trap.[38]
Shadow the Hedgehog[]
Knuckles and Shadow the Hedgehog do not have much interaction with each other, but when they do, they are either allies or rivals. They started off as indirect enemies during the Space Colony ARK incident because Shadow impersonated Sonic and had him thrown in jail at Prison Island as well as being associated with his own arch-rival, Rouge. Toward the end of the game, they became allies when they had to save the planet from the Space Colony ARK.
The first real fight between them happened during the Neo Metal Sonic incident, when Team Dark provoked Team Sonic into battling them, although Shadow did not remember Knuckles and his teammates. After the fight, Knuckles jokingly mentioned that they might have fought Shadow's ghost and scared Tails.
In Shadow the Hedgehog, Knuckles appears in Glyphic Canyon, Central City, and Black Comet stages asking for Shadow's help in Hero missions.
During the Solaris incident, he and Shadow were loosely allies, and they worked together again for a time in order to return to the present and save all of reality from Solaris in the end.
Shadow and Knuckles appear to have some bitter resentment towards each other as seen in Sonic Rivals when Shadow bluntly pointed out that Knuckles was useless for his shortcomings while retaining an indifferent attitude towards his challenges, whilst Knuckles, briefly trying to be cordial, was irritated by Shadow's haughty presence. In Sonic Rivals 2, Shadow is willing to hinder Knuckles' search for the Master Emerald to keep him from getting the Chaos Emerald while indecisively refusing to explain his motives, even starting a fight with him, ultimately leading Knuckles to mistakenly assume he was involved in the Master Emerald's disappearance. Knuckles seems to find Shadow and his smug demeanor annoying, and it is likely that Shadow's inflated ego tends to rub Knuckles the wrong way, and examples of this is seen in Sonic Free Riders when Knuckles pointed out that Shadow had a big ego in a rather annoyed tone after Team Dark beat Team Babylon and remarked to Tails he and Rouge weren't ones for team loyalty as they showed no compassion for E-10000B. Even so, Knuckles possesses respect for Shadow, cheering him in his fight against Devil Doom in Shadow the Hedgehog. In Sonic Forces, Knuckles was shocked to hear about Shadow causing trouble in Sunset Heights, wondering why he would "work for the enemy". As it turned out that the real Shadow was not working with Eggman, Knuckles fought alongside him in the penultimate battle against the Eggman Empire as an ally. Overall, Knuckles and Shadow's relationship revolves around their goals.
Rouge the Bat[]

Knuckles saving Rouge, from Sonic Adventure 2.
Rouge the Bat is Knuckles' primary rival. Knuckles and Rouge have been fighting over the Master Emerald since they first met. Rouge was designed to be Knuckles' counterpart just like how Shadow was designed to be Sonic's counterpart when it comes to basic rivalry and skills.
During the Space Colony ARK incident, they became enemies when they met because Rouge had stolen the Master Emerald from him and was later working with Shadow and Eggman. Also, Knuckles purposely shatters the Master Emerald to save it from Dr. Eggman. Knuckles and Rouge both go looking for its pieces. Eventually, Knuckles has to hunt Rouge down for the remaining pieces, and the two have their final confrontation at the level, Meteor Herd. But at a standstill, he saves her life instead after she slips on a narrow beam and was about to fall into a burning pit of lava. After the rescue, Rouge and Knuckles share a long moment gazing at each other, before Rouge snatches her hand away and retorts with ungratefulness and teasing. In the end, Rouge gives him the remaining pieces of the Master Emerald and stubbornly complains that "they stink like echidnas do!". Knuckles gathers the shards to complete the Emerald and glances over to her, muttering "I'm sorry if I hurt you..." and runs off. Before the scene fades out, Rouge gives a thoughtful smile over her shoulder before exiting.
In Sonic Heroes, at the end of Team Dark's story, Rouge commented that she would go look for the Master Emerald, "since that irritating echidna is here." However, in the last scene, she went to Knuckles and coquettishly hinted about going to look for someone else's treasure. Knuckles smiles and says, "She never gives up, does she?"
During the Solaris incident, Rouge and Knuckles were bitter allies during their mission to travel back to the present day but joined up with him to collect the seven Chaos Emeralds to bring Sonic back to life.
During the Ifrit incident, the two teamed up. Rouge's reason for this is because she had a mysterious client who told her that if she found all the Emeralds, she would be rewarded. She teamed up with Knuckles in search of the identity of her client. They fight the Ifrit to get back to normal depending on which side you play. Knuckles also asked Rouge if she was alright when they won against the Ifrit, showing his concern for her, and the only reason why he fights her in the last level is because she's struggling to break free from mind control.
During the Wisp incident, Knuckles explains to Rouge that he is at Starlight Carnival because he received an invitation from Dr. Eggman but proving that he did not get tricked. Rouge tells him that the invitation was written by her, causing Knuckles to burst into anger.
During the Time Eater incident, Knuckles and Rouge oddly seem to be friendly to each other at Sonic's birthday party, as they are seen setting the table, eating, smiling, and talking to each other. They are also friendly with each other in Sonic Forces, and Rouge holds no qualms with being a spy under Knuckles' command, even acknowledging him as "boss".

Rouge and Knuckles, from Sonic the Hedgehog #30.
In Team Sonic Racing, in Dodon Pa's Grand Prix, Knuckles, and Rouge's rivalry is shown most friendly. Despite the instance of him ramming her in a race between their teams[39], they are able to be amiable with Rouge throwing some playful banter. Despite their improving interactions, Knuckles is still wary of Rouge due to her lingering interest in the Master Emerald, becoming defensive when she is even brought up[18].
Knuckles and Rouge can get along well, but the former usually is annoyed by the bat's antics and obsession with the Master Emerald. Rouge has teased Knuckles with this several times, but he has not responded very positively to it. While Knuckles tolerates her presence on his island when needed, he has limited patience when it comes to Rouge. In addition, Rouge has been known to jokingly flirt with Knuckles, which flusters him.[29][30]
Vector the Crocodile[]
Knuckles and Vector the Crocodile are on good terms with each other, having been friends since the Chaos Ring incident, with Knuckles considering Vector (and the rest of the Chaotix) one of his most trusted friends. However, they do not interact often with one another in the present day. Regardless, Vector gave advice to Knuckles when Team Sonic was fighting Metal Overlord, apparently acknowledging his great power.[40]
In Sonic Free Riders, the two did not have a friendly relationship, as Knuckles felt underwhelmed having to race against Vector and the rest of Team Rose, treating them like a joke as he was irritated by their loud behavior. Although Vector managed to defeat Knuckles one time, the echidna still said he would not get far with brute force, enraging the crocodile.
In Sonic Forces, the two were comrades in the game, and they appeared to work very well together, as Vector was a high-ranking member of the Resistance. The two also appeared to have considerable respect for each other, and Vector unsurprisingly appreciated Knuckles for his aggressive (yet sometimes short-sighted) generalship[41] considering Vector's own liking of non-peaceful methods.
Espio the Chameleon[]
Knuckles has known Espio the Chameleon for a good while and are close allies in time of need. They both have a mutual trusting relationship, with Knuckles considering Espio (and the rest of the Chaotix) one of his most trusted friends. They are not immune to minor conflicts at times, as Knuckles mentions that Espio once spread through reading a book to him very quickly, also spoiling the ending for him, much to Knuckles' dismay.
Blaze the Cat[]
Knuckles first met Blaze the Cat when Cream wanted Blaze to be friends with him. Knuckles was initially very friendly and cordial towards Blaze before he noticed Blaze holding a few Sol Emeralds, which he mistook for Chaos Emeralds. He, therefore, gave Blaze advice to give them to Sonic. Blaze got angry at Knuckles and told him that she did not have any Chaos Emeralds. Knuckles then got angry at her and accused her of lying, and then made an attempt to attack her. Blaze dodged Knuckles' attack and knocked him out, leaving him to lie in a crevice. When Knuckles regained consciousness, he developed a loathing towards Blaze and wanted revenge. When they met once again, Knuckles nearly started a fight with Blaze, but he was stopped by Amy. Cream also convinced Blaze that Knuckles was actually a "nice guy", which made Blaze feel relieved. Soon, Knuckles let go of his grudge and befriended Blaze.
Bark the Polar Bear[]
Knuckles first met Bark the Polar Bear during the Death Egg II incident, Knuckles after that considers Bark one of his rivals but not a friendly one either. Knuckles will even tease his ability to beat him in a fight which would give Bark the consent that he is weak, but him and Knuckles are not buddies nor friends either.
Storm the Albatross[]

Knuckles and Storm, from Sonic Free Riders.
When Knuckles and Storm the Albatross met, Knuckles punched Storm really hard while the latter was trying to commit a theft, which caused Storm to fall from his Extreme Gear. Ever since then, the two have been rivals over who is the stronger man. When Storm lost against Knuckles in the World Grand Prix, he falsely accused him of having cheated. During the MeteorTech incident, the two also showed a spark of anger when they saw each other again. In this encounter, Knuckles thought of Storm as a "meathead" while Storm wanted to settle the score between them, causing great tension between the two.
Silver the Hedgehog[]
Knuckles and Silver the Hedgehog appear to have a friendly relationship with a small rivalry between the two. Although they do not have much interaction with each other, they have had heated battles with one another occasionally. Silver and Knuckles first meet, albeit briefly, during the Solaris incident. Despite only meeting in End of the World, Knuckles appears to be impressed with Silver's determination and cheers on the hedgehog in his fight against Solaris.[42] Following the timeline reset when Solaris' flame was extinguished, the pair re-meet during the Onyx Island incident. Knuckles initially showed his dislike of Silver when he first met him, mainly because he thought that he was pompous and stuck-up. Silver's haughty and prickly attitude also tended to annoy Knuckles. However, they later put aside their differences and willingly teamed up together. In Sonic Forces, Knuckles was the first-person Silver warned about Eggman's attack, which led to the War to Take Back the Planet. In the game, Knuckles and Silver appear to be on very good terms with each other and work very well together. In fact, Silver appeared to be one of Knuckles' most trusted lieutenants, an indication that Knuckles has considerable respect for Silver.
Avatar[]
During the War, Knuckles, as the commander of the Resistance, recruited and introduced the Avatar to the others, remarking that they were the only survivor from Infinite's attacks who came to join the Resistance. However, the others did not seem to think much of the Avatar at first, with Charmy commenting that they did not look like much. Despite this, Knuckles defends the Avatar and supports them throughout the war, regularly referring to them as "rookie". It is not until after the conclusion of the war that Knuckles, now acknowledging the Avatar as a true hero, drops the nickname. Furthermore, when the Avatar decides to go their own way in order to help more people, Knuckles does not try to stop them.
Trip the Sungazer[]

Trip hugging Knuckles, from Sonic the Hedgehog: Knuckles' 30th Anniversary Special.
Sometime after the Northstar Islands incident, Angel Island passed by the Northstar Islands. Noticing this, Knuckles decided to visit Trip the Sungazer to train her to become a better guardian, as he doubted her abilities as a guardian. In his initial attempts to train Trip, he ended up pushing her too far, causing her to run away crying. After thinking about past experiences with his other friends, he decided to change his approach in training her. He proceeded to apologize to Trip and explain his story to Trip, which Trip was fascinated by. The two then made up after Knuckles reassured to her that she is a great guardian. Since then, the two have had a more positive relationship with each other, with Knuckles acting as a mentor to Trip.[43]
