Shadow: Rouge and Shadow are teammates and current best friends in Sonic Adventure 2 and Sonic Heroes and often work together during mission stages, but are not seen together outside of duty alliance and do not spend time in one another's presence unless it is business. Nonetheless, Shadow is one of the few people Rouge cares about, other than herself. It has been implied that she may have feelings for Shadow.[10]

In Sonic Adventure 2, Shadow saw a comparison to Maria in Rouge and saved her life when she was trapped in Security Hall. Despite how he later dismissed his actions saying he only returned for the Chaos Emeralds that she had acquired, Rouge suspected that there was more to his reason for saving her than he let on.

In Sonic Heroes, Rouge forms Team Dark with Shadow and Omega. During this time, Rouge and Shadow become much closer than they were in Sonic Adventure 2; interacting more within Team Dark as partners alongside Omega. Rouge is willing to help the amnesiac Shadow get answers about his past and is shown to have concern for him when they discover the existence of Shadow Androids.

In Sonic Battle, Rouge calls Shadow "not bad-looking" and "a prince". She also lets him stay with her at Club Rouge when he is injured during a fight after carrying him inside when he passes out in front of the club. Also, while Shadow is dreaming, an image of Rouge appears and he whispers, "Ally." Rouge seems offended when Shadow doesn't thank her for saving him, but later he thanked her when she told him that she actually rescued him.

In Sonic Rivals, after Shadow saves Rouge from Eggman Nega, Rouge tries to persuade him into going treasure hunting with her and suggests the two "take a peek" into their own future using Eggman Nega's device. Shadow declines and the story ends with Rouge still trying to convince Shadow to join her in hunting for the remaining cards.

In Sonic the Hedgehog (2006), Rouge makes an attempt to draw Shadow into a conversation that doesn't involve Mephiles' plan to destroy the world, and at one point she says, "It's always business with you." when Shadow ignores her and rejects the off-topic sessions. Although, Shadow also shows he is protective of Rouge's well-being. Once, when catching her from a fall after she was momentarily knocked out by one of Dr. Eggman's robots. And again, when he jumps in front of her defensively, after a fake Chaos Emerald explodes. After E-123 Omega reveals to Shadow that he is the one who traps him in the future, Rouge tells Shadow, that she will always be on his side no matter which side he takes, Shadow pauses, then replies strongly replies that he will. Though, in the original Japanese version of the video game, Rouge simply says, "You always have friends to whom you can rely on."

In Sonic Free Riders, both Shadow and Rouge appear as Team Dark along with E-10000B. Their main focus during the game is winning the treasure and prize money. Unlike in previous games, Shadow seems perfectly content with helping Rouge obtain the treasure she covets. (Note: This is the only time Shadow has appeared in a game with the intent on making money, rather than his usual ulterior motives, although the manual implies that Shadow also joined for the sake of competing against Sonic of who had the better skills.)

Knuckles: Knuckles the Echidna is Rouge's primary rival and the two have been fighting over the Master Emerald ever since they met. Out of all the characters, Knuckles is most distrusting of Rouge, as her desire for jewels will often cause the Master Emerald to be targeted for theft. Unbeknownst to Knuckles, Rouge has a crush on him, but she would never admit it.[6] She has thus been known to deny having such feelings for him, like in Sonic Chronicles: The Dark Brotherhood where she said he was cute, but not her type. Regardless, she is secretly inspired by Knuckles' determination to protect the Master Emerald.

In Sonic Adventure 2, when Knuckles purposely shatters the Master Emerald to save it from Doctor Eggman, Knuckles and Rouge both go looking for its pieces. But during their fight, he saves her life. Rouge and Knuckles share a short moment gazing at each other before Rouge snatches her hand away and retorts with ungratefulness by teasing that he just wanted to hold her hand. In the end, Rouge gives him the remaining pieces of the Master Emerald and complains that, "They stink like echidnas do", to imply her stubbornness. Once the Master Emerald is restored, Knuckles needlessly apologizes to Rouge in case he had hurt her and runs off. Before the scene fades out, Rouge gives a thoughtful smile over her shoulder before also heading out.

In Sonic Heroes, they don't have much interaction with each other. When their teams cross paths, Knuckles clearly did not take Rouge's trash talk too well. At the end of Team Dark's story, Rouge commented that she would go looking 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 (hinting the Master Emerald), with Knuckles commenting "She never gives up, does she?" before running after her.

In Sonic Chronicles: The Dark Brotherhood, the codex states that "there's a sort of unstated connection between Rouge and Knuckles that neither are overly willing to explore."

In Sonic Rivals 2, the two are teamed up. Rouge's reason for this is because she had a mysterious client who told her that if she found all the Chaos Emeralds, she would be rewarded, so she believed with Knuckles she might find her client to know exactly who he was. When Sonic first saw Knuckles and Rouge together, he teased them, asking them if they were on a date. Rouge is hostile towards Knuckles. She however, supported Knuckles throughout the game but later on deceived him by calling him "dashing and daring" in order to distract him while stealing the Master Emerald, much to his fury before chasing after her. Most recently, in both the first and final cutscenes of Sonic Generations, Knuckles and Rouge are seen having a conversation at Sonic's birthday party. They appear to be communicating in a friendly, lighthearted way.

In Sonic Forces, Rouge and Knuckles don't show any sort of rivalry going on, as they are both determined to save the world. Rouge also seems happy to be a spy for the Resistance with Knuckles, who amiably trusts her, as its commander; she even calls him "boss", showing clear respect towards him.

Omega: Rouge's other best friend is Omega, who is very loyal to her. She prevented Shadow and Omega from destroying each other in Sonic Heroes, and soon after they formed Team Dark to help her find Eggman's "secret treasure room". Instead of finding treasure, of course, they end up saving the world, and Team Dark has been a tightly-knit trio ever since. The two are close allies, and Rouge cares for her robot friend, such as in Sonic Chronicles, where she voices her desire to help Shadow find Omega in Metropolis, stating to hate the thought of him rusting away and not with them "blowing things up".

She has sometimes shown annoyance at Omega, saying that he is too serious and she is tired of hearing him ramble on about revenge and hatred.

Amy Rose: Rouge and Amy are generally portrayed as bitter rivals towards each other. Their relationship is similar to Rouge's relationship with Knuckles; after him she distrusts Rouge the most. In Sonic Battle, the two fight several times over Emerl. When Amy called Rouge's house a "dump", Rouge was furious about Amy's comment and the two started to fight over the Emerald Shard.

Their dislike for one another is also apparent in Sonic Chronicles: The Dark Brotherhood. They aren't always bickering, however, as shown in Shadow the Hedgehog. When Shadow had saved the world and defeated the Black Arms in the last story, Rouge wonders, "I hope he's okay." Amy comforts her by saying, "I'm sure he's fine, Rouge. After all, he is Shadow." Rouge then looks back at her and nods in agreement. Also, at the end of Sonic Forces, they seem to be having a friendly conversation.

Sonic: As seen so far, Rouge and Sonic don't really show a dislike for each other, despite him being Shadow's arch-rival and she being Knuckles' rival. Also, despite having some conflicting encounters and standpoints, they appear to be on good terms. They were at first enemies in Sonic Adventure 2, because Rouge was working with Shadow and Eggman, but became allies towards the end of the game to save Earth. And after Shadow's supposed death after defeating the Finalhazard, Sonic comforts her by giving her his gold ring. In Sonic Battle, Rouge challenges him to a battle, if she wins, Sonic will have to get her gems and work for her. Sonic manages to win however, but he did not hold any grudge against her as seen later on. Later, Sonic let Emerl say hello to Rouge, which suggest Sonic somehow trusts her. In Sonic Chronicles, Rouge flirts with Sonic and gave him the nickname, "Big Blue". She uses the nickname again in Sonic Generations when rescued.

It is worth noting that in Sonic Generations, Rouge is one of the voluntary attendees at Sonic's birthday party and that Sonic treated her as all of his other friends, which shows a friendly relation between them. If Classic Sonic rescues her, she tells him to watch out for the Time Eater, then adds that he's not the Sonic she knows.

Although they do get along they still sometimes get into fights, like in Sonic Heroes when Team Sonic and Team Dark fought in a jungle and in Sonic Battle when she kidnapped Emerl to train him to be a thief. He also told her if she did something to Emerl, he wouldn't let her off easily. When Rouge was introduced to Emerl, she gave them an idea to help Emerl, Sonic refused, calling her 'a thief'. Whether this means their friendship has grown since then or that Sonic just does not trust her completely is yet to be seen.

• Rouge may have been named after the jewel, the Rouge, relating to her jewel obsession. Her name could also come from a type of makeup applied to the cheeks (also called "blush").
• Another possibility is that her name is a play on the word "Rogue", often used as a synonym for "Thief", mirroring how she often steals other peoples’ jewels.
• In Sonic Heroes, while selecting Shadow or Omega to be Team Dark's leader, if you use the first-person camera to look at Rouge, she will occasionally turn her head in the player's direction and wink.
• To date, Rouge has never appeared in any Sonic game without Shadow appearing in the same game, cameo or not.
• Between Sonic Adventure 2 and Mario & Sonic at the Olympic Winter Games, Rouge's fangs appear to be absent.
• One of Rouge's unused lines ("Pleasure before business!") from Sonic Adventure 2 is used in one episode of Sonic X.
• After Sonic Adventure 2, Sega decided to change Rouge's outfit (explaining why she wore something different in Sonic Heroes) to make her look less provocative, but they ultimately decided to change it back as they found the new outfit to be even more provocative than the old one.
• Not counting team members in the support class, Rouge has the least team POW moves in Sonic Chronicles: The Dark Brotherhood, with only one.

• Rouge possesses enormous physical strength that rivals that of Knuckles the Echidna's. However, whereas Knuckles' strength lies in his upper body, Rouge's lies in her lower body, particularly in her legs and feet, giving her enormous kicking power. With her kicks, she can shatter boulders, slice through metal, or even leave dents in thick steel walls. She can even split her opponents in half with precise kicks and create small earthquakes to trip opponents by striking the ground.
• With her wings, Rouge is able to achieve flight and can glide by using her wings to manipulate her descend. When flying, Rouge can move as fast as Knuckles' gliding, but not as fast as Sonic or Shadow can run. Nevertheless, Rouge possesses an innate quickness, making her fast on her feet and can reach super speeds when running, though she is still not as fast as Sonic, Tails or Shadow.
• Rouge has proven herself to be quite acrobatic, precise and agile, on both the ground and in midair due to her government training. She is able to perform all kinds of actions and movements while in midair effortlessly, grind on rails and as well perform several types of nimble movements in combat with incredible precision.
• Much like Knuckles, Rouge is an expert climber and can climb on any kind of surface, no matter the material. She is also excellent at digging and tunneling through subterranean regions. She is also a very experienced swimmer, possibly due to her being a treasure hunter, enabling her to swim with both great speed and skill, and can reach amazing depths.
