Chaotic Space Zone boss

The Chaotic Space Zone boss is a mech that appears in Sonic the Hedgehog Pocket Adventure. It was a mech created by Dr. Eggman and used by the doctor to combat Sonic.

Appearance
The Chaotic Space Zone boss is a giant mech ressembling an Eggrobo (with red eyes, a red and yellow upper body mimicking Dr. Eggman classic attire, a black underside and a gray round head) with 2 red rockets under its robotic legs. It also has one gray rocket launcher at the extremity of each of its two bolted robotic arms and also red bolted dropping holes where beige mines can be dropped from on the mech's back. It also has ventilation holes in the back of the mech's head and gray extremeties around it as well. Color-wise, it's identical to the palette of an actual Eggrobo with its legs and the bolted parts of its arms (including the shoulders) being of a red color.

Powers and abilities
Eggman's vehicle, as a rocket-propulsed mech, is capable of space flight. In terms of offensive capabilities, it can fire rockets from its rocket launchers and drop mines from the holes in its back.

Sonic the Hedgehog Pocket Adventure
In Sonic the Hedgehog Pocket Adventure, Dr. Eggman used this mech first to flee, then to attack Sonic when he continued to chases him in Super Sonic form from the Last Utopia Zone. In spite of Eggman's efforts though, his vehicle got destroyed by Sonic in the end, leaving Sonic to be finally victorious over Eggman one more time.

Battle
The Chaotic Space Zone boss is the true final boss of Sonic the Hedgehog Pocket Adventure. The player fights it at Chaotic Space Zone.

Boss guide
When the player arrives at Chaotic Space Zone, Dr. Eggman can be seen entering his mech with his Eggmobile. Afterward, the head of the mech will cover Eggman, initiating the boss battle. During the battle, Eggman's mech will flee rightward and the player have to chase after him while being careful not to come short on rings by catching them along the way during the level. Eggman will periodically attack using his rocket launchers that can shoot in three directions. He will also periodically attack using his flashing mines that will scatter around the arena from his back. Eggman will repeat these attacks during the entire fight until he's defeated.

To defeat this boss, the player has to hit Eggman's mech eight times. Since charging into Eggman will hit the player back, the player have to dash into the missiles Eggman is launching, in the right direction, to reflect them towards the mech. The player has to be careful not to get hit by the waves of mines since they'll drop out regularly and are not scattered around necessarily in a single part of the boss arena, making it hard to dodge them all, nor by the rockets if they aren't repelled.

After being defeated, Super Sonic will come closer to watch the Chaotic Space Zone boss as it will blow up. This will leave Eggman without protection on his Eggmobile as he'll beg Sonic to show mercy. Sonic will dashes through him anyway, leaving behind a panicking Eggman on his exploding vehicle as he crash into the Earth, clearing the game. The good ending will play as Super Sonic reenters the planet's atmosphere to be picked up by Tails on his Tornado plane. Sonic will come back to his normal form, leaving the Chaos Emeralds to scatter around once more while the habitants cheer Sonic victory in a now peaceful world. Sonic and Tails will pass near Knuckles (that found again his purple Emerald) before flying away above the ocean to parts unknown.

Trivia

 * The theme music the Chaotic Space Zone boss uses is the Sky Sanctuary Zone theme from Sonic & Knuckles.
 * The boss is quite similar to the Doomsday Zone boss (altough physically it have rockets instead of legs, faces leftward toward Super Sonic instead of rightward and have rocket launchers instead of hands). The way to defeat the previous boss is quite different however than this one, with the former needing to be hit directly by Sonic instead of having its missiles reflected towards it, having a first phase absent from the Chaotic Space Zone boss and avoidable asteroids that aren't present in the Chaotic Space Zone unlike the Doomsday Zone.
