°Metal virus!>•

Metal Sonic's appearance resembles that of Sonic the Hedgehog, but he has distinct differences that indicate his robotic nature:
covered with blue metal instead of wool;
has black eyes with red pupil rings instead of Sonic's white eyes and green pupils;
Instead of white gloves, he has iron claws. His entire body is covered in scratches and dents. His job is to watch Cream. He can't speak. He sometimes carries out other tasks for Tails and Eggman.

Whisper has brown skin and biscotti-colored fur. She has thick black eyelashes, cloudy white fur around her eyes, and cadet-blue eyes that are often squinted. She wears light gray eyeshadow, has a long, fluffy tail with tufts of fur at the end, a black nose, long, pointed ears, and fairly long hair that she pulls back into a ponytail with a black hair tie. Her bangs cover her right eye. Whisper often frowns, revealing her fangs.
In battle, she wears a cream-colored top, light gray leggings, a dark gray cloak with pockets, dark gray and light gray gloves with visible claws, knee pads, and military-style boots. She sometimes dons an ornate cat mask in cream, dark gray, and light gray. Three holes are visible on the right side of the mask, and a blue "eye" on the left, the color of which changes depending on the Wisp power she is using. She never removes the mask. She hasn't spoken a word in the past two years and has no intention of doing so. She strictly follows all of Knuckles' orders. She wears an orange handkerchief on her knee—the last vestige of her best friend, Tangle.

At stage 4, it can fly thanks to its large metal wings.

A corpulent man with an egg-shaped build, a small bald head, blue eyes, a pinkish-red nose, and a thick mahogany-colored mustache. He wears a red jacket, black pants, and blue-violet glasses. He is 185 centimeters tall and weighs 128 kilograms. He is narcissistic, selfish, arrogant, and tyrannical. He is convinced that his vision and ideas are the only correct ones, and that global problems can be solved under his control. Metal created a virus that has gone out of control. Everyone hates him and sincerely wishes him ill, but he is a genius with 300 IQ, which means he can help with the antidote. He is strictly not allowed out of his room. He has become more athletic. He is searching for the antidote.

Starline has gray fur, a pointed tail, red eyes with pale yellow sclera, and black eyelids. He wears a purple shirt with gold cufflinks, a red-violet vest, orange pince-nez, and always carries a brown glove with gold tips on the fingers. On the one hand, he is fanatically devoted to Eggman and wants to help him; on the other, he is constantly consumed by envy and a thirst for recognition, which drives him to his own, far more ambitious and insidious plans. He is cruel, hypocritical, selfish, and manipulative. Starline was the only one who knew the antidote to the virus, but he was killed, thrown into a vat of the metallic virus by Cubot (Eggman's robot), where he was killed.

Wave has purple and dark purple feathers on her body and head, with lighter shades on her arms and legs, styled like flame tattoos. Her hair is a pair of long pigtails with darker feather tips. She has a curved golden beak, blue eyes, and two tail feathers pointing upward.
Wave wears:
white gloves with cuffs;
gold bracelets;
white top;
white flared trousers with purple fire pattern;
red boots with a white stripe and dark gray soles;
necklace with red gemstone;
sunglasses with yellow lenses and white frames;
white bandana. Missing, whether she is dead or alive, no one knows.

Infinite has long white dreadlocks, a fluffy tail with a white tip, and white stripes down his back that resemble ribs. He wears black gloves with silver stripes on the back and pointed metal high-tops with an infinity symbol on the red soles.
After fusing with Ruby, he wore a silver mask with large ears adorned with black and white circular patterns. His eyes are different colors: the right one is blue with a scar, the left one is yellow. Phantom Ruby grants Infinite powerful abilities:
Reality Distortion. He can create illusions with material substance that not only deceive the eye but also cause physical damage.
Levitation.
High speed and agility. Cruel, cold-blooded, arrogant, selfish, and egocentric. He promises everyone paradise on Angel Island, but with cruel rules (no one believes him). He's located on Angel Island. He's obsessed with catching Shadow.

The armadillo's body is covered in black fur, and its head and back are protected by a thick red shell. Its ears are funnel-shaped and set on its sides, its eyes are normal with black pupils, and its muzzle and ear skin are yellowish-brown. Mighty wears white gloves and cuffs, and its footwear has changed over time: first, red sneakers with gray soles and white straps, then red sneakers with dark soles, white trim, and a transverse white strap with metal trim. Scars from whip wounds appear on its chest. It is Infinite's henchman and executioner. Nothing can be said to him. Gloomy, pessimistic. His physical strength has become even greater than before.

Sonic has been infected. He's in stage three. The fastest of all the other infected, he no longer has super speed or agility. A tall, thin figure with sharp claws and soulless black eyes with red pupils and a frozen smile.

Vector was infected, becoming a metallic monster with sharp claws and a massive body. His victims never become infected because they don't survive long enough. He is in the third stage of the virus.

Espio has purple fur, a yellow horn on his nose between his golden eyes, a crest of three black spines running along his back, and a curled tail. He wears dark purple boots with black accents and metal trim, white gloves with purple backs, and spiked bands around his wrists and ankles. He is an anthropomorphic chameleon. He is a realist, a pessimist, calm, reserved, and reasonable. He wears a brown scarf. He can turn invisible. He is agile and resilient, and has combat skills.

An anthropomorphic lop-eared rabbit with cream-colored fur covering most of her body. She has an orange stripe on her head. Her eyes are oval with brown irises and markings around them. Her muzzle is white, and the skin inside her ears is pink. Her medium-sized nose is dark brown. She wears an orange dress with a blue tie and yellow and orange sneakers. For swimming, she wears a yellow one-piece swimsuit with a hot pink skirt and light, knee-high metal boots. She is unaware of what is happening outside.

Shadow is an anthropomorphic hedgehog. He has black fur and quills with red stripes. He has become infected, currently in stage one, although he should have progressed to stage two long ago. A second eye has opened on his forehead. He has no mouth, meaning he cannot speak. Large, bony metal wings are always visible behind him. He avoids survivors. His mind still functions, but it's a little clouded.

Light silver (almost white) fur covering most of the body.
Five vertical flexible spines on the head, two of which cover most of the ears.
Two long needles on the back of the head, reaching the shoulder blades.

A realist, a bit optimistic, calm. Has the power of psychokinesis. Returned from the future to help and save his future. Has immunity to the virus.

A young anthropomorphic fox with two tails that allow him to fly. He wears a dark green jacket with a hood trimmed with gray fur. There are slight shadows under his eyes from lack of sleep. He always sits in his small room, monitoring the tracker attached to the infected Sonic, and trying to find an antidote. He's a realist, a pessimist. Since the virus arrived, he's become emotionless, but still kind at heart.

Rouge has white fur, tanned skin, turquoise eyes, and distinctly feminine features. She has large, pointed ears, small fangs, a black nose, a short tail, and a pair of purple-black wings on her back. She often wears makeup: blue eyeshadow and pink lipstick.
Her typical outfit is a black, sleeveless, form-fitting jumpsuit, a pink, heart-shaped top with white trim, tall white gloves, and boots with pink cuffs and heart-shaped heels and metallic trim. She's realistic, strict, and still a little flirty.

Amy is an anthropomorphic pink hedgehog. She has green eyes, and her spines are not protruding, but rather styled, somewhat reminiscent of a bob. She usually wears a red sleeveless dress with white trim, high red boots with a white stripe and metal trim, white gloves with gold bracelets, and a red hairband. She's an optimist, but since the virus, she's become a moderate realist. She often feels sorry for others and treats everyone with kindness and a little sternness.

Knuckles is an anthropomorphic echidna. His quills resemble short dreadlocks, and his fists have enlarged knuckles (two on each hand), which is where his name comes from. He wears white gloves with spiked knuckles and red sneaker-like boots. He has red fur. He has prosthetics in place of one arm and leg, reflecting how he was previously injured by the infected, and to avoid becoming one of them, they amputated his limbs. He is a pessimist, a bit gruff, and calm.

Jet has dark green markings on his wrists that resemble flames. Jet has dark emerald feathers on his body and white feathers on his chest and stomach. He has blue eyes and a golden beak. The feathers on his head are styled into a mohawk with dark green tips, and he has two tail feathers. He has dark green markings on his wrists that resemble flames. He wears red, black, and white boots with gray soles with a metal base. He carries a Aero-board with him at all times and everywhere. He is rude, brash, and aggressive. After the loss of his girlfriend, Wave became even more hot-tempered. He is a pessimist. Jet is an anthropomorphic hawk.

•A catastrophe has occurred, and the metal virus has escaped Eggman's control! There are several stages: 1. The flesh becomes completely metallic, and the mind is completely lost, and the victim has only one goal: to infect. 2. The limbs begin to distort. 3. The victim becomes increasingly unrecognizable, and they no longer want to infect, but... 4. The body is no longer there, and only the head remains, and the metal begins to emit a dangerous gas that infects the lungs. 5. ... And now let's move on to the survivors - Amy - remains unharmed and always at the base, Knuckles - carries out missions and has prosthetics instead of an arm and a leg, Tails - remains unharmed, always at the base and helps Eggman with the antidote, Eggman - remains unharmed, everyone wants him dead, but he is the creator of the metal virus and a genius, without whom nothing can happen, Espio - goes on missions, unharmed, Silver - helps everyone, his only task is to save the future and help the survivors, immunity to the virus, all in scars and scratches, Rouge - remains at the base, unharmed and helps others, Blaze - in a coma, without a leg and an arm, Jet - unharmed, aggressive and hates Eggman, saying that he needs to be expelled, helps on missions, Cream - unharmed, always at the base, Rouge is watching her, Infinite - promises everyone that he will take everyone to paradise on Angel Island, but With strict rules (no one believes him), Mighty is Infinite's henchman and executioner; you can't tell him anything. There's also the missing Wave, Jet's friend, but rumor has it she's already infected. Eggman previously betrayed his assistant Starline by throwing him into a vat of the metal virus, the first person to die from the metal virus, although only he knew the antidote. Significant infected include Vector, the most dangerous, at stage 3 of the virus, very strong; Sonic, at stage 3, the fastest of all the infected, constantly repeating the name Tails; Champy, at stage 4; Shadow, whose third eye has opened on his forehead, doesn't attack anyone, and always has metal wings behind his back; he's at stage 1 and no longer advances in stages; Infinite is obsessed with catching Shadow.
