The Last Utopia Zone boss is an oval hovercraft with a windshield, gray armor, and a round green gem inside the vehicle's nose on the front. It also is equipped with four small gray rockets on its back, and has two massive robotic arms attached to its sides. Each of these arms have three fingers on their hands. The vehicle's forearms are bolted and each of them possess a small gray rocket hidden inside its elbow socket. Also, on the vehicle's back, there is a gray circular receptacle to hold a Chaos Emerald. It also has a black underside, a red line below its nose, red upper arms, and red wristbands. It also has yellow and black hazard stripes on its sides and on its underside.

Powers and abilities

With a Chaos Emerald serving as its power source, the Last Utopia Zone boss is a powerful machine. It is capable of high-speed flight, and can both detach its arms and fire them like rockets at their targets, allowing it to hit foes from afar.


Sonic the Hedgehog Pocket Adventure

In Sonic the Hedgehog Pocket Adventure, while on the run from Sonic in Last Utopia Zone. Dr. Eggman boarded the Last Utopia Zone boss and faced Sonic head-on. As an addition, the doctor inserted the purple Chaos Emerald he took from Knuckles in a previous encounter into his vehicle in order to empower it. In spite of Eggman's efforts though, Sonic took back the Chaos Emerald from the vehicle, which the hedgehog subsequently destroyed, thus forcing Eggman to flee into space.


The Last Utopia Zone boss is the seventh boss and final standard boss of Sonic the Hedgehog Pocket Adventure. It is fought in Last Utopia Zone.

Boss guide

When entering Last Utopia Zone, Sonic will be chasing after Dr. Eggman, automatically collecting nine Rings along the way. When Sonic enters the arena, Eggman come out of hiding in the Last Utopia Zone boss, laughing and holding the purple Chaos Emerald. Eggman will then insert the Chaos Emerald into his vehicle's receptacle, starting the boss battle.

The Last Utopia boss possesses three forms of attacks. Its first form of attack is charging at Sonic in an attempt to grab him. If it succeeds, the boss will shake him violently in order to damage him. Its second form of attack includes shooting its forearm at Sonic like a rocket when he is out of range. Its third form of attack involves the boss stretching its arms out and spinning itself around across the arena. Its last attack is by far its most dangerous as it covers a greater range that its other attacks.

To defeat this boss, the player has to hit Eggman's vehicle eight times. However, the player has to be careful not to get hit by the boss's arms when its is spinning or when it attacks using its rocket-based forearms. To avoid these attacks, the player must either jump above the arms or, in the case of the rocket-based forearms, duck under them.

To acquire the purple Chaos Emerald attached to the Last Utopia Zone boss, the player has to physically hit the Emerald. If the player deals enough hits to the Chaos Emerald, it will fall off the boss, thus allowing the player to grab the Emerald and add it to their collection. This is an advisable strategy if the player has already acquired the other six Chaos Emeralds from the Special Stages.

After being defeated, the Last Utopia Zone boss will blow up. If Sonic has all seven Chaos Emeralds at this point, Eggman will flee into space in his Egg Mobile while Sonic pursues him to the edge of the Zone before transforming into Super Sonic and following Eggman into Chaotic Space Zone where the game's true final boss awaits. If the player has not gotten all seven Emeralds by then however, Eggman flees to the edge of the Zone in his Egg Mobile, where he pleas for Sonic to not hit him. Hitting him at that point destroys Eggman's Egg Mobile, along with the entire Zone, giving the player the bad ending of the game.
