Intro:
The blue blur is back in Sonic 4: The Hedgehog—a fan-made fourth entry that raises the stakes from high-speed fun to multiversal peril. Set after the events of Sonic 3, this chapter dives into the heart of chaos energy, lost timelines, and a dark reflection of Sonic himself.
Main Plot:
Peace returns after the battle with Shadow, but it doesn’t last. Strange distortions ripple across the world—time skipping, zones collapsing, and familiar friends… disappearing. The cause? The Prime Emerald has fractured, scattering pieces of reality itself.
From the rift comes Scourge the Hedgehog—a corrupted, alternate Sonic from a parallel dimension where speed led to tyranny. With the help of an army of rogue Chaos constructs, he’s here to steal what’s left of Sonic’s world and make it his own.
To stop him, Sonic must team up with unlikely allies: Silver from the future, a restored Shadow still wrestling with his purpose, and Blaze the Cat guarding a key to the multiverse. Together, they must venture through twisted versions of Green Hill, ancient ruins lost to time, and the Zero Core—a space between worlds.
But time is running out. If the Prime Emerald isn’t restored, reality itself will unravel—and Sonic’s greatest enemy may turn out to be… himself.

Tone & Vision:
Vibrant, emotional, and turbo-charged—Sonic 4: The Hedgehog blends high-speed adventure with bold sci-fi stakes. Think Into the Spider-Verse meets Sonic Generations, where style meets substance, and nostalgia meets new lore.
Expect dynamic action sequences across collapsing landscapes, electric synthwave soundscapes, chaos energy battles in midair, and quiet moments of reflection on who Sonic truly is when speed alone isn’t enough.
