Villains
Doctor Eggman is a genius, hot-tempered, and dreams of world domination; a plump, egg-shaped man in a red jacket and purple glasses, he's always dissatisfied with his coffee machine.
Eggman Nega is Eggman's calculating and cruel doppelganger; nearly identical to him, but with a colder gaze, as if calculating betrayal even before the handshake.
Infinite is a former mercenary possessed by the power of the Phantom Ruby; masked and heavily armored, he moves with a predatory stance, watching from the shadows as if waiting for the perfect moment.
Zavok is domineering and fierce, and doesn't tolerate weakness; tall, angular, with sharp spines and fiery eyes, Zeti seems to take up more space than he should even in a room.
Metal Sonic is an emotionless copy of Sonic, acting like a machine; he has a shiny metal body and red "eyes," mimicking the original's movements but lacking a soul.
Black Doom is an ancient alien overlord, eerily calm; a dark, massive figure with horns and glowing eyes, his silence is more oppressive than any scream.
Chaos is the spirit of chaos, changing form from a fluid mass to a monstrous creature; a translucent, watery substance that flows smoothly across the floor, leaving wet marks.
Commander Walters (GUN) is a pragmatic and ruthless military man; his stern uniform, stern gaze, and reserved, commanding gestures suggest he's assessing strategic points even in his living room.
Silkadoom is a hybrid of Sonic and Shadow's DNA, corrupted by negative energy; black and red coloring, jagged spines, scars and shimmering patches, and a gaze that darts between rage and pain.
Solaris, an ancient flame and shadow, is trying to adjust to life; a Mobian-like figure, but yellow-white in color and with dark slits for eyes, keeps quiet, as if afraid to burn down this cozy home.

Nazo is a cold and calm hedgehog with light blue fur, white gloves with white cuffs, and blue sneakers whose half is red with white cuffs.

Heroes
Sonic is cheeky, carefree, loves speed and chili dogs; a bright blue hedgehog in red sneakers, always on the move, even when he's just watching TV.
Tails is a shy, smart guy who loves technology and helping his friends; a red fox with two tails, white gloves, a flight helmet, and a soldering iron, he looks right at home.
Knuckles is proud and straightforward, jealous of secrets and dislikes fuss; a red echidna with massive knuckles and spiky dreadlocks, he sullenly ensures that everything is done "fairly."
Shadow is collected and cold, hiding his pain behind rigid principles; a black hedgehog with scarlet stripes and gold details on his shoes, he maintains a detached demeanor but doesn't miss a single detail.
Amy Rose is energetic and stubborn, believing that the Pico-Pico hammer and a kind heart solve everything; a pink hedgehog with a bow and a determined look, she manages to bake, grumble, and protect her friends.
Silver is an idealist who strives to save the future but often gets lost in the present; a light silver hedgehog with yellow eyes, he moves cautiously, as if afraid of breaking something.
Rouge is cunning and calculating, but loyal to her people; a bat in a tight suit, she glides around the room with feline grace and a grin.
Cream and Cheese - Cream is gentle and caring, Cheese is her cheerful companion; a cream-colored bunny in a dress and bow and a small Chao next to her - an island of comfort in the chaos.
Charmy is hyperactive and loud, but disarmingly sweet; a little bee who darts around the room promising to clean up "in five minutes."
Vector and Espio - Vector is charismatic and loud, Espio is calm and precise; a crocodile with a confident gait and a chameleon who is almost invisible until he speaks.
