She is portrayed as a professional treasure hunter dedicated to the pursuit of jewels, calling herself "the world's greatest treasure hunter," and also as an anti-heroine. She has a tendency to disregard abstract morality or ways to gain potential profit; her "feminine charm" makes her seem careless, but she is actually audacious, fearless, cunning, and intelligent. Furthermore, she serves as a spy for the human government. Rouge is an ideal spy, capable of being shrewd, manipulative, deceptive, strategic, observant, and discreet. However, the character has a compassionate side, as she is willing to listen to someone rather than rush into violence and will not hesitate to protect the world when the situation demands it. Rouge also has a sense of humor, often at the cost of teasing her friends, and a disarming flirtatious nature. She fights with kicks, especially her signature "Screw Kick," and can fly with her wings. Like real-life bats, Rouge has an excellent sense of hearing, enough to allow her to hear even Espio, a master of stealth and invisibility, when he is near her.

It is said that Shadow is equal to Sonic in almost every ability; Shadow can easily rival the blue hedgehog's various physical abilities. His skills and combat abilities are an extremely powerful force to be reckoned with, and he is a match for even the most powerful enemies in the series. He also never holds back his immense strength willingly, which makes him a brutal fighter. Single-handedly, Shadow was able to take down several GUN combat mechs, Dr. Eggman's battle robots, Black Doom and his strengthened state, and even deities. To better put his abilities into perspective, Shadow was even able to defeat Sonic while he had Diablon as support.

Silver is a silver hedgehog who debuted in Sonic the Hedgehog (2006). He is 18 years old. Despite possessing great speed, Silver doesn't run as fast as Sonic and Shadow. Fans speculate that, just as Eggman Nega is a descendant of Eggman, Silver could be a distant descendant of Sonic or Shadow. He is quite intelligent, extroverted, and sarcastic, but has the terrible habit of jumping to conclusions, which has given him a reputation for being unlucky among Sonic's friends. However, Silver is quite naive, insecure, and impulsive, which makes him act compulsively and without thinking many times. He always does everything he can to achieve his goals; however, he is somewhat pessimistic and doesn't always see the bright side of a situation. Normally, he is rather serious, but he can also smile. He considers himself better than Sonic in terms of personality, being more responsible and mature than the blue hedgehog, but he seems to show respect for him as a hero.

Silver possesses psychokinetic powers, allowing him to control virtually everything around him, as well as use them on himself to fly. When using these powers, Silver is enveloped in an incandescent turquoise aura. He can also shoot from the circles on his hands; these shots can pierce almost anything. He has also demonstrated telepathic powers. His partner is Blaze the Cat, for whom he harbors a romantic affection.

A princess from an alternate world who is 18 years old. She is quick and possesses the ability to control fire (Blaze in English means flames).

Blaze the Cat is Silver's best friend, and she tries to change the future alongside her by defeating Iblis Trigger once and for all to bring peace.

When she went to Sonic's dimension, she wasn't very friendly with anyone until she met Cream, and from then on they became friends.

Blaze is the protector of the Sol Emeralds. Blaze is a very focused, serious, introverted, and shy girl; she greatly enjoys being alone and rarely trusts people. The cat considers herself very self-sufficient and carries heavy responsibilities on her own; because of her self-confidence, she doesn't accept help from others. After Sonic taught her about friendship, however, she became more communicative, kind, gentle, and generous towards people. Blaze is very responsible and does not forgive those who try to attack her kingdom.

Cream is a rabbit. She is 15 years old. Cream is Amy's best friend. Cream is the most polite of all, always treating everyone with great formality and honesty. She always tries to maintain positive thoughts for herself and her friends, being quite friendly with everyone. She is described as a very cheerful, optimistic, sweet, simple, generous, and compassionate character. However, her curiosity and impulsiveness can sometimes get her into trouble. And when faced with intense difficulties, Cream's optimism and joy can easily disappear. Despite fighting for the side of good, Cream doesn't like violence very much and prefers to lead a peaceful life taking care of those she can, but in certain situations she may get into fights and adventures. She can flap her long, floppy ears to create upward momentum and fly. However, she cannot fly very fast and gets tired in the process, and is quite physically strong, able to carry heavy things like Big. Cream can speak to and understand all types of Chao, but she can also train them to obey her commands and give them new abilities. A great example of this is her pet Cheese, who is well-trained by her and very useful in various situations. Cheese also has a curious ability to transform into characters in comical versions. A very interesting fact is that, with her positivity, she can heal herself and the people around her.

Cheese has the appearance of a neutral Chao child: He is light blue with yellow markings on the tips of his head, hands, feet, and tail, a bulb-shaped head, dark blue eyes, a yellow pom-pom ball hovering above the top of his head that changes appearance according to his emotions, two pink butterfly-like wings, and a small circular tail. He is distinguishable from other Chao by his red bow (the color may be pink, depending on the game being played). Cheese is a very loyal Chao and is always ready to help Cream. His mood tends to reflect Cream's, like a "shared feeling": when Cream is happy or upset, so is Cheese.

Amy Rose is a 19-year-old pink female hedgehog with a huge passion for Sonic. She is nicknamed "Rosy the Rascal".

Amy is cheerful, optimistic, proactive, kind, caring, and selfless. She's a very determined hedgehog who lets nothing stand in her way. She's a sweet and loving character, but can also be temperamental, proud, aggressive, bossy, and arrogant at times. She's quite extroverted, friendly, and innocent, making friends with any character, even villains, to convert them to the side of good.

Like Sonic, she also sometimes enjoys fighting villains and is quite adventurous. She has a strong sense of responsibility and duty, along with great leadership skills. Because she lacks the strength or speed of other characters, she uses her extremely powerful magic hammer, called the "Piko Piko Hammer," as a weapon and has also learned kickboxing and boxing as martial arts. She can use tarot cards to predict the future, foresee the past, track people, track objects, and curse enemies. She has also used these abilities without the aid of tarot cards to protect people and her friends.
