Sonic the Hedgehog is a free-spirited hedgehog who hates dishonesty and lives by his own rules. He is the fastest hedgehog in the world, able to run at supersonic speed, and is always on the move. Despite his impatience, he has a kindness that prevents him from ignoring those in trouble, and he always keeps his promises.
Miles Prower, known as Tails, is a kind-hearted fox with two tails that he can rotate to fly. He loves tinkering with machines and develops various mecha. Inspired by Sonic, he admires him and hopes to become someone Sonic can rely on.
Knuckles the Echidna is a cheerful and powerful echidna who lives alone on Angel Island, guarding the Master Emerald. He is Sonic's rival and sparring partner, with a stubborn and inflexible nature that makes him easily tricked. He is a treasure hunter and martial arts master with powerful fists, and can glide and climb walls.
Amy Rose is a bright and energetic hedgehog who is Sonic's self-proclaimed girlfriend and follows him everywhere. She hates losing and has excellent initiative. In critical moments, she pulls out her Piko Piko Hammer from nowhere, showing performance that rivals any of the boys.
Silver the Hedgehog is a silver hedgehog with psychokinetic powers who came from a future world. He has a strong sense of justice and an honest, warm personality that never gives up hope even in desperate situations. He possesses high combat capabilities that allow him to stand against Sonic and Shadow.
Dr. Eggman, real name Ivo Robotnik, is a self-centered and arrogant self-proclaimed evil genius scientist with an IQ of 300. He loves mecha and is incredibly overconfident, with high pride, and is easily irritated. He harbors the idea of turning the world into 'Eggman Land' and never gives up, with his ultimate wish being to defeat Sonic.
Shadow the Hedgehog is a black hedgehog who looks exactly like Sonic. He is the Ultimate Lifeform created by Professor Gerald, Dr. Eggman's grandfather. He was granted the ability called 'Chaos Control,' which uses the power of the Chaos Emeralds to warp time and space. He possesses a terrifying purity, willing to use any means necessary to achieve his own goals.
Metal Sonic is a Badnik modeled after Sonic by Eggman to defeat him, and Sonic's first rival. He has a cold personality and always acts calmly, having dueled Sonic many times to prove that he is the one true Sonic.
Blaze the Cat is the princess of her world, entrusted with the mission to protect and wield the Sol Emeralds. She usually maintains a calm and dignified appearance, but this seems to be because she tries to suppress her inner passions with reason. She is very shy in groups, but since meeting Sonic and his friends, her mindset seems to have changed slightly. She can travel between Sonic's world using the power of the Sol Emeralds.
Rouge the Bat is a wild and sexy bat woman. She is a treasure hunter specializing in jewels, and she never fails to obtain a target once she sets her sights on it. While she may seem frivolous at first glance, she is extremely calculating and a significant realist. She decides her actions based on profit and loss rather than justice or morality.
This is Green Hill, the place where Sonic and his friends live. However, there is also a certain human who dreams of world domination and constantly harasses them.
