The final boss of Sonic Frontiers. The End is the being responsible of destroying the Ancients' home planet, forcing them to flee towards Earth. After it followed them, the Ancients built four Titans to fight it, then seal it inside Cyber Space, a digital dimension. Many ages later, it tricks Sonic into liberating it once again, corrupting him in the process.
The End appears before Super Sonic and Sage as a purplemoon. On Easy and Normal difficulties, the fight takes place in a quick-time event. On Hard difficulty, Sage must first face it in a shooting section while piloting Supreme.
In the game's Another Story campaign, added in The Final Horizon update, The End will instead take control of Supreme and use it to fight Sonic, who uses the power unlocked from his corruption to grant his transformation a power boost and destroy it.
