Death Egg (デスエッグ[1][2][3]), also known as Robo Eggman (ロボ・エッグマン[4]) or Robot Eggman[4], is the final boss of Sonic the Hedgehog 2. It is a huge robot made in the likeness of Dr. Eggman.


The robot towers over Sonic, bristling with antennae and sensor dishes. Its torso is spherical, with red and yellow paintwork mimicking the Doctor’s own jumpsuit. Immense robotic limbs branch from the central mass, secondary motors roaring as the arms swing and titanic feet ram down one in front of the other. A pink dome of a head bulges out from the top of the central sphere; vast metallic moustache twitching back and forth beneath its pointed nose.


The robot will take four steps toward the player, half a step back, then launch off the screen. The Player has to jump and hit him, but the robot has two spiked fists about halfway up his body. Touching these or his legs will kill the player and force them to fight Mecha Sonic again. The player must jump and hit him above the spiked fists. This is very difficult to do at any time, but the safest times to do it are when he is standing still and not taking a step. Hitting the bot when it is walking is considerably more risky, although it's the only way to win the battle quickly. The safest time to hit him is when he bends down slightly (This happens at two points, when he stands still a moment before he launches and right after he appears or lands). Don't hit him when he takes his last step forward since one of his fists will be extended forward.

After he launches, a white target circle appears on the player's character and follows the player wherever they go. When a smaller circle appears inside the larger one, it means the target has locked on, and won't follow the player. This is the time to move. The robot will come down where the target locked on.

He will then shoot both fists, one at a time. The fists don't fly all the way across the room. Eggman will, after launching his fists, launch again, and repeat the last step with the target and try to land on his enemy. After that, the entire sequence will repeat.

If the player is able to get behind Eggman at any time when he lands, he'll stay stationary and launch two Eggman-shaped bombs at the player. The bombs fall where the character was standing when they launched and explode shortly after they land. Eggman is not as vulnerable from behind as he is from the front so this is a disadvantage. After shooting the bombs, he will launch upward again.

After defeating the second boss, the player's character runs off the edge of the exploding Death Egg, ending the level and leading to the Sonic 2 ending sequence.

Playing as Knuckles

This is the hardest level boss-character combination for this game. Since Knuckles doesn't jump as high as Sonic or Tails, another strategy must be used.

The peak of his jump puts him horizontally level with the spiked fists. This means the player can only hit above the arms when the robot is bending down. It is possible to score hits under the arms using glide but this requires timing and precision almost impossible to keep up. The player must avoid the temptation to hit the robot when it is walking, as they will die.

It is also possible to score hits if Knuckles is behind the robot, where he can score hits by jumping into the robot's weak point.


When hitting the robot when it is bending down, it is possible to pass through the outline of the robot chest and die upon contact with the arms. To avoid this, always pull back as soon as contact with the chest has been made. Knuckles can effortlessly work around this glitch by gliding into the robot; he will always bounce away after hitting.

Other game appearances

This boss returns as a final boss again in Sonic the Hedgehog 4: Episode I's E.G.G Station Zone, and once again as a boss in Sonic Generations, now called the Death Egg Robot. The robot would also appear as a boss fight in Lego Dimensions, and as the boss of Green Hill Zone in Sonic Mania.

In Sonic Forces, Eggman would mass-produce autonomous versions of this robot and use them in his conquest of the planet, destroying locales such as the City. In Sonic Frontiers, a partially destroyed robot resembling its Forces counterpart is seen on Chaos Island, referred by Tails as an Assault-class Death Egg Robot.
