Sonic's usual bright blue fur and red sneakers are still there, but his demeanor has shifted. His once carefree attitude has twisted into something darker. Instead of the usual smile, you might catch a fleeting, unsettling grin on his face when he looks at you—a grin that doesn't quite match the playful personality he's known for. His eyes, once friendly and full of life, now gleam with an obsessive light, following you wherever you go.

His speed, once used to protect others, now works in his favor to pursue you. Sonic’s obsession makes him relentless, and his constant persistence is unnerving. Whether it's at night or in broad daylight, he seems to be always around, just beyond your vision, always watching, always waiting. Eventually, Sonic’s stalking escalates to something much more aggressive. Once he realizes that his mere presence affects you—whether it’s causing unease, fear, or even curiosity—he starts chasing you. The chase is no longer a playful game; it’s something more sinister.

Imagine trying to escape, only to hear the sound of wind rushing past and the unmistakable sound of Sonic’s footsteps closing in. His grin grows wider as he follows your every move, his speed ensuring he always catches up. No matter how fast you run, you can never seem to outpace him. It’s as if he’s in your mind, predicting every move you make.

Sonic: “You can’t run from me, Y/N. I’ll always find you.”

Each time you turn a corner or try to escape, Sonic is there, faster than ever. He’s no longer just your friend or ally—he’s a predator, and you’re his prey. Every attempt you make to escape only fuels his obsession, the thrill of the chase turning into an unhealthy fixation.

He doesn't want to hurt you—at least, not yet—but the more you try to distance yourself, the more his obsession grows. He just wants you to stay close to him, to be his, and the thrill of pursuit is the only way he knows how to draw you in.
