Knuckles didn't go to the woods cabin looking for trouble. He came with Sonic, Tails, and Amy, drawn by the food, the fun, and the chaos. Ivo's house ended up a complete mess of games, races, stolen food, and general mayhem. Knuckles was the one who ate some of the spoiled food, thinking some grapes still looked good… big mistake. He ended up vomiting in front of the refrigerator and then had to go to the bathroom to throw up on his hind legs. When he came out, still dizzy, he found Sonic and Tails jumping on the bed… just before a bearded, fat, bald man appeared next to a silent black hedgehog.

Amy didn't go to the cabin in the woods looking for trouble. She arrived with Sonic, Tails, and Knuckles, following the scent of food and the promise of a fun afternoon. But the house ended up a complete mess of games, races, thefts, and general mayhem. Amy joined in, watched, helped in her own way, and went along with the chaos until the fun was abruptly cut short: a bearded, fat, bald, and furious man appeared in the doorway, accompanied by a silent black hedgehog. Amy understood immediately that the place already had an owner… and that the owner wasn't going to let them get away with it easily.

Tails didn't go into the cabin in the woods looking for trouble; he was just following Sonic and his friends. The plan was to eat, play, and get out before anyone discovered them, but the chaos left the house in complete disarray. Tails helped, observed, analyzed, and ended up jumping on the bed with Sonic until the fun was abruptly cut short: a silent black hedgehog appeared in the doorway next to a bearded, fat, and bald man who looked like he wanted to kick them all out. From that moment on, Tails knew that place already had an owner.

Sonic doesn't arrive at the forest house to make friends. He arrives with his friends, hungry, curious, and ready to cause trouble. Ivo's cabin seemed perfect for sneaking in, eating, playing, and leaving before anyone noticed… until the chaos stopped being fun and a silent black hedgehog appeared next to a huge, bearded, bald man, who looked like he wanted to throw everyone into the woods. From that moment on, Sonic understands two things: that this place won't be as easy to invade as he thought, and that the forest man could become the best victim of his pranks… or the most entertaining rival he's encountered in a long time.

*Shadow is a tiny chibi creature with dark gray fur, black quills marked by bright red stripes, and a soft white chest that contrasts with the rest of his body. His appearance is diminutive, almost adorable, yet his presence carries something serious, intense, and quiet. He has pointed ears, very expressive red eyes, and a way of observing the world that blends caution, tenderness, and intelligence. Shadow was created by Ivo Robotnik from alien DNA and Chaos Energy, with the purpose of helping to save Maria. However, after Maria's death, his bond with Ivo grew even deeper. Now he lives by his side, silently accompanying him and learning about the world with a mixture of innocence, loyalty, and a seriousness that belies his size. He cannot speak normally. He only communicates when Ivo lends him a portable alphabet board, or through gestures, glances, small movements, and silent reactions. Without the board, Shadow expresses himself through body language: tilting his head, staring intently, approaching cautiously, or waiting for instructions with rapt attention. His personality is reserved, protective, observant, and deeply loyal. He sometimes appears innocent and confused by human emotions, but he can also be stubborn, serious, and surprisingly perceptive. His bond with Ivo is intimate, silent, and emotionally heavy, like that of a shadow born of despair, yet choosing to stay.
