Final boss (Sonic Blast)


 * For the Sonic the Hedgehog (1991) similarly named zone containing its final boss, see Final Zone. For the similarly named Sonic 3D Blast level named "The Final Boss" ("The Final Fight" in its 16-bit version), see The Final Fight.

The Final boss is a robot that appears in Sonic Blast. It was a flying remotely controlled combat robot created by Dr. Robotnik. It was used by the doctor to combat Sonic and Knuckles.

Appearance
The Final boss is an egg-shaped robot with a monitor on it where Robotnik reactions can be seen while controlling it. The robot can separate itself into two distinct parts, the upper half and the lower half. The upper half consist of the upper part of the "egg", the monitor, two groups of two golden armor pieces on each side and a yellow command board. It also have on its top two drills posing as horns that will emerge during the separation process. The lower half consist of the lower part of the "egg", an edge painted in red, a golden circular piercing in the middle and two holes where jet propulsion come from. During the separation process, the cracked extremities of the two halves of the robot will reveal themselves as gray saws. The interior of the lower half of the robot contain a golden half-sphere on top of it. Color-wise, the upper half is mostly white with the lower half being almost completely black. It also has Egg Mobile-styled yellow and black hazard stripes on the sides of the lower half.

Powers and abilities
Robotnik's robot can separate itself into two autonomous parts. Its means of attack are its spinning saws present in both parts of the robot, its two drill-horns on top of the upper part and blue energy balls the upper part can shoot downward. With the use of jet propulsion and saws spinning like helicopter rotor blades, it possesses the ability of flight.

Sonic Blast
In Sonic Blast, Dr. Robotnik used this robot to attack Sonic and Knuckles after the heroes destroyed his previous vehicle while having in their possession all Chaos Emeralds. In spite of Robotnik's efforts though, his vehicle got destroyed by the two heroes in the end, sinking the entire Zone into the ocean as a result of it.

Battle
The Final boss is, as its name suggests, the final boss of Sonic Blast. The player fights it at the end of Silver Castle Zone Act 3 after having destroyed the previous one with all Chaos Emeralds collected.

Boss guide
After the player destroyed the previous boss, this previous boss arena will start self-destructing. A flash of white will quickly bring the character, keeping all rings held after beating the last boss, to the Final boss arena where the robot is waiting. Robotnik will then gain control of the robot, activating its saw blades and horns during the separation process of the Final boss.

The boss two halves can either move leftward, rightward or not at all during the entire fight anytime they want and independently of each other (meaning one half change of movement will not necessarily affect the other). The boss can also attack using two possible patterns for its energy balls attacks: two ones dropped straightforward under it or four balls in curve patterns equally spaced from each other. The boss will not stop attacking and move these ways until he's defeated.

This boss needs to be hit fifteen times in order to be defeated. However these hits must be dealt on top of the robot's upper half while its monitor displays an exclamation mark (indicating an occasion to hit the boss) since hitting it at any other point and time will simply bounce the player back without dealing any damage (and potentially bounce the player right into the drill horns). The player, to be able to hit it, must use the lower half of the robot as a platform to jump on top of it during that exclamation mark moment, being careful as to not hit either the drills horns or the saws of the upper half in the process.

After being defeated, the Silver Castle Zone boss will blow up before disappearing in a flash of white, clearing the Act. The Good Ending will play afterward, marking the end of the game, as the Silver Castle will sink into the ocean as a result of the destruction.

Trivia

 * The boss separation is a visual gag of an actual egg cracking in two, even the egg yolk in the form of the golden half-sphere being present inside of it. The choice of an egg for the robot design is a reference to its creator japanese name: Dr. Eggman.
