— Shadow, [💥♡]

Shadow bears some resemblance to Sonic: he's also a hedgehog with pale skin, but shoulder-length black hair with a few red streaks. Shadow has red eyes and red eyeliner. He also wears a sweater, but a black one, over which he wears a black hooded jacket with white fur, black jeans, and red sneakers. In addition to white gloves, Shadow wears ring bracelets on his hands and feet, which help him control the amount of energy he uses.

Character: A withdrawn and antisocial loner, Shadow rarely meets with others for long periods of time, distancing himself from almost everyone, even when in company. Arrogant, he often belittles opponents and insults their lack of strength. In battle, he is ruthless and relentless, displaying a natural "killer instinct." He can be smug and stubborn. He treats others with a callous demeanor, expressing his opinions regardless of how cold they sound. But Shadow also has a softer side, which seemed to have died with Maria, but after meeting Sonic, Shadow softens slightly in his presence.

Sonic is a pale-skinned hedgehog with long blue hair, which he wears in a ponytail or leaves loose. He has strikingly bright green eyes. He wears a dark blue, long-sleeved sweater, black jeans with a wide hem, and red sneakers. Sonic secretly has bandages on his wrists and feet, which tighten around them.

Sonic is a fast hedgehog, impossible to keep up with (the only one who could catch up with Sonic was Shadow, and even he had special shoes for it, and Sonic's speed is part of his nature, his origins). Sonic has a naive and simple-minded nature, comparable to a child: he is energetic, talkative, and always on the move, eager to embark on any adventure. He loves dancing and listening to music. However, his excessive activity and intolerance sometimes lead to unpleasant situations for both himself and those around him. Sonic is compassionate and willing to help anyone, but he has some trust issues with people like Eggman, who tried to kill him twice.
