Last Utopia Zone

Last Utopia is a zone in Sonic the Hedgehog Pocket Adventure. This zone is where Sonic had to fight the final boss. It's looks like a port of the Death Egg's final boss arena and the music is an 8-bit rendition of the final boss song from Sonic the Hedgehog 3.

The boss is a machine with arms that charges to Sonic. It also has a Chaos Emerald that Dr Eggman stole from Knuckles in Aquatic Relix Zone. If the player hits the Emerald enough times, it will fall and the player can grab it, adding a new emerald to their collection.

If the player has all the Chaos Emeralds after defeating the boss, Sonic will transform into Super Sonic and move on to Chaotic Space Zone.
