Sonic

Knuckles is an anthropomorphic red echidna. He has broad shoulders, a powerful chest, and thin legs. His arms and legs are wrapped in bandages, emphasizing his fighter-like appearance. He wears spiked fabric gloves. He often mixes up his words, doesn't understand sarcasm, and takes everything literally. Despite his naivety, he is extremely self-confident. He considers himself a brilliant strategist (though his plans usually boil down to "hit harder") and even a feminist. He is extremely loyal to his friends and has a heart of gold. Knuckles will never abandon the team in trouble, even if he forgets why they came there in the first place. He is the team's "tank." He can smash walls, lift enormous boulders, and smash through Eggman robots with his bare hands.
Amy is an anthropomorphic pink hedgehog. She wears a pink dress with a white collar and purple sash, tall pink boots, and purple gloves. Like the rest of the team, her boots and wrists are wrapped in bandages. She has more precise bobbleheads, secured with a pink headband. Amy is the most emotionally mature of the group. She often mediates disputes between Sonic and Knuckles. Her faithful companion is the Piko-Piko hammer. Amy masterfully swings it, creating shockwaves. She is incredibly agile and flexible, allowing her to dodge attacks from Eggman's robots with the grace of a gymnast. She loves planning holidays, keeping to-do lists, and maintaining order. Sometimes her passion for control verges on fanaticism. Amy is interested in history, archeology, and art. She is an excellent decorator and even a cook (although her desserts sometimes cause chaos).

Styx is a wild anthropomorphic female badger. She has orange-brown fur with two distinctive eye stripes, long hair pulled back into two messy ponytails with chestnut-colored ties, a gray top and a rough fabric skirt tied with rope, and wears various fur boots, a necklace of shells and gold rings, and bracelets on her wrists. Styx is extremely suspicious, believing in government conspiracies, aliens, and a "machine uprising," which often makes her appear insane. She uses a boomerang as a weapon, sniffs her friends, and makes strange compliments.

Tails is an anthropomorphic fox, Sonic's best friend, and the team's technical brain. He wears brown aviator glasses with orange lenses, a utility belt with a shoulder strap for storing tools and gadgets, red sneakers with a bandage around the midfoot, and two tails that he uses for flight and sprinting. Tails is optimistic, loyal to his friends, and often serves as the team's voice of reason. He strives to be taken seriously as a fighter, not just a "cute fox." He creates highly complex devices.

Sonic is a blue anthropomorphic hedgehog. His fur is a rich blue. Blue fur covers his entire body from his shoulders to his hands. Beige (peach) skin remains only on his muzzle and stomach. His eyes are emerald green. The quills on his head point downward, appearing tousled and "prickly," seemingly divided into smaller, sharp strands. Short, "shaggy" appendages are added to the main long quills on his sides, creating the effect of constant movement. He has two small blue quills on his back, and a short, sharp tail at the back, typical of hedgehogs. Bandages are tightly wrapped around his forearms, starting from the wrists (just behind the gloves) and extending almost to the elbows. This creates the image of a fighter ready for hand-to-hand combat. Bandages are placed over his shins and partially cover the top of his sneakers. It looks like extra ankle support, necessary when running through the uneven jungle. His boots are bright red with chunky gray soles with tread for running on mud and rocks. On his left wrist (over the bandages), Sonic wears a high-tech bracelet. It allows him to project an energy beam—a blue light rope—which he uses to cling to ledges or attract enemies. Around his neck is a brown scarf (bandana). He is confident in his abilities, sometimes to the point of arrogance. He often makes fun of friends and enemies. Unlike Shadow, who considers friendship a weakness, Sonic draws strength from it. He is very loyal to his team, although he sometimes argues with them. Sonic hates boredom. If nothing happens for a long time, he begins to act impatient and even irritable. Despite his cool appearance, he still has a fear of water (he can't swim) and sometimes shows insecurity when it comes to leadership responsibilities. He's the fastest character, with a blue energy trail as he runs. Sonic curls into a spiky ball to smash robots or break through obstacles. Despite his sarcasm, he holds Tails, Knuckles, Amy, and Sticks dearly. He loves chili dogs.
