Sonic The Hedgehog: Uprising (Season Four; Series Finale)

Destiny fulfilled

With Metal Overlord defeated and Mobius in ruins, the Resistance struggles to rebuild. But peace is shattered once more when a forgotten threat from the stars emerges—Black Doom and the Black Arms, alien invaders who once experimented on Shadow and now return to finish what they started: transforming Earth and Mobius into a new hive world. Sonic and his allies must face their most cosmic battle yet, rallying a fractured world, unlocking the Final Chaos Power, and discovering the ultimate truth behind Shadow’s origin. The final season is a race against extinction, identity, and fate.
