Neo South Island Zone boss

The Neo South Island Zone boss is a vehicle that appears in Sonic the Hedgehog Pocket Adventure. It was a tracked Egg Mobile created by Dr. Robotnik. It was used by the doctor to combat Sonic.

Appearance
The Neo South Island Zone boss is a modified Egg Mobile that uses gray tracked wheels attached to it for transportation instead of jet propulsion. Like an Egg Mobile, it got a small protective glass on the front and gray edges. It also got two brown mufflers on the back of the vehicle. It uses a sledgehammer manipulated by a gray mechanical arm as its main weapon. In terms of coloration, it is mostly red with a black underside and the Egg Mobile's usual yellow and black hazard stripes.

Powers and abilities
Robotnik's vehicle can roll on the ground using its tracked wheels. Its main weapon is a giant sledgehammer that can hit the ground so hard it causes small earthquakes.

Sonic Blast
In Sonic the Hedgehog Pocket Adventure, Dr. Robotnik used this vehicle to attack Sonic when he was passing through Neo South Island Zone. In spite of Robotnik's efforts though, his vehicle got destroyed by him in the end.

Battle
The Neo South Island Zone boss is the first boss of Sonic the Hedgehog Pocket Adventure. The player fights it at the end of Neo South Island Zone Act 2.

Boss guide
When the player arrive in a wide empty area at the end of Neo South Island Zone Act 2, Dr. Robotnik with his vehicle will jump right into the right side of the arena. He'll then roll toward the left side of the arena, slamming the ground with his sledgehammer before going off-screen. He will then come back doing the same thing except that he'll go rightward before going off-screen again at the right side of the arena. He will then come back and go leftward before stop after a few seconds, holding his hammer before slamming it to the ground so hard the ground will shake (leaving Sonic to be temporarily paralyzed if he was on the ground during that hit). Robotnik will continue going leftward and come back from the off-screen again, starting the whole process over again (albeit from the opposite direction each time) until he is defeated.

This boss needs eight hits to be defeated. However, the player must be careful not to be hit by the sledgehammer and stay in the air when Robotnik's earthquake slam will be done (with the quake leaving Sonic to be potentially hit by Robotnik sledgehammer soon after if not getting rid of the shock effect) to defeat the boss.

After being defeated, the Neo South Island Boss will blow up before Robotnik flees in his Egg Mobile, leaving the player to open the capsule and clear the Zone in doing so.
