Shadow

Eggman is more of an "annoying neighborhood villain" than a mad dictator. He's comical, vain, and charming in his own way. He has broad shoulders and a powerful chest, but very thin legs and a waist. He wears a modern red military uniform with yellow buttons and epaulets. He has black gloves and high boots. His famous brown mustache is neat and pointed. He always wears blue goggles on his forehead. His evil plans can range from taking over the world to trying to burn down the local burger joint simply because he didn't get enough sauce. He still builds incredible robots (Orbot and Cubot are his constant companions). He has a flying chair (the Eggmobile) equipped with lasers, missiles, and mechanical grippers. He is obsessed with his image. Eggman might give up on his plan to take over the world if someone says something bad about his mustache or if he can't take a great selfie.

Shadow is an anthropomorphic black hedgehog with red eyes. He has broad shoulders and long limbs, giving him a more athletic and menacing appearance. He has six main quills on his head. The four upper quills are curved upward, while the two lower quills point downward. Under the upper quills are small extensions resembling "cowhorls" or unruly strands of hair. He also has two quills on his back and a short, pointed tail. Bright red stripes run along the edges of his upper and side quills on his head, and are also present on his eyelids, arms, and legs. A small tuft of white fur is located in the center of his chest. The skin on his muzzle and inside his ears is a flesh-colored (beige) tint. He wears white gloves, and the back of his hands has a red inlay. He has high black and red cuffs that fit tightly around his forearms and are secured with special clasps. On his wrists, over the cuffs, are massive gold wrist guards. His boots are a complex mechanism that allows him to glide across the ground at supersonic speeds, leaving a trail of red energy in his wake. They are predominantly white, with a black area on the heel and a long red "tongue" at the top. The boots have gold rings. On the bottom are red metal plates and four small jet nozzles (three in the front and one on the heel) that emit flames when accelerating. He disdains friendship, considering it a weakness. He mocks Sonic for relying on a team. Shadow is convinced of his absolute superiority. He enters battle to prove he is the best. Thanks to his boots, he doesn't just run, but floats above the ground, allowing him to maneuver at incredible speeds without losing his balance. Shadow doesn't engage in protracted combat. He uses a series of teleports, delivering quick and powerful blows from all sides until the enemy is disoriented. Unlike Sonic's acrobatic and playful style, Shadow fights effectively and brutally. His strikes are aimed at knocking out his target. He can curl into a ball for attacks.

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.
