The Egg Mobile-H,[1][2] also known as the Egg Mobile Hammer Ball-shiyou (エッグモービル・ハンマーボール仕様[1] Eggumōbiru Hanmābōru-shiyō?) or the Egg Wrecker,[3] is a vehicle that appears in the Sonic the Hedgehog series. It is a modified version of the Egg Mobile created by Dr. Eggman, who first used it during the South Island incident.



The Egg Mobile-H takes the same appearance as that of the Egg Mobile. Oval in shape, it possesses its usual windshield and seat. However, it also features a long, gray chain with a large, checkered brown wrecking ball in the end of it.

Features and abilities

The Egg Mobile-H is capable of flight, although it is incredibly slow compared to the standard Egg Mobile. During the first part of the Death Egg mk.II incident, it was shown that it is able to rotate 360 degrees very quickly to to slam the wrecking ball.

Game appearances

Sonic the Hedgehog (1991)

In the original Sonic the Hedgehog, the Egg Mobile-H is named the Egg Wrecker.[3] It is fought at the end of Green Hill Zone Act 3. In the original game, it is encountered by Sonic. In the 2013 remaster, it can also be fought with Tails and Knuckles.

The battle takes place on a flat piece of grass with two floating platforms above it. Dr. Robotnik will fly down into the arena and lower the wrecking ball from the Egg Mobile. He will then move slowly back and forth across the screen in a linear pattern, swinging the wrecking ball from side to side.

To defeat the Egg Wrecker, the player must leap onto one of the floating platforms and then Spin Jump into the hovercraft. The only thing the player has to look out for is the wrecking ball itself, which can damage them, although they are able to dodge it easily. After hitting the Egg Wrecker eight times, it will explode while the chain and wrecking ball gets destroyed. Dr. Robotnik will then flee, allowing Sonic to open the capsule, thus freeing all the animals inside of it and completing the Zone.

In the 2013 remaster of Sonic the Hedgehog, the battle arena has been extended to fit the new widescreen aspect ratio while the movement pattern of the Egg Wrecker has been increased in size to match. At the start of the battle, the Egg Wrecker can no longer be damaged until the wrecking ball is completely deployed.

Sonic the Hedgehog 3 & Knuckles

The Egg Mobile-H later makes an appearance as a mid-boss during Sonic's version of Sky Sanctuary Zone in Sonic & Knuckles and Sonic the Hedgehog 3 & Knuckles. It takes place approximately one-third of the way into the zone, in a similar arena to the original fight. Unlike other versions of the battle, the Egg Mobile is now piloted by Mecha Sonic. In Sonic & Knuckles, it is encountered by Sonic. In Sonic the Hedgehog 3 & Knuckles, it can also be fought with Tails.

The battle is mostly similar to the original, however the pattern of the Egg Mobile is slightly different. When Mecha Sonic arrives at the other side of the arena, he stops the Egg Mobile and lets the wrecking ball swing to a very high height until it falls down in a similar way. The player has to hit the Egg Mobile eight times while avoiding the swinging wrecking ball. Like in the original Sonic the Hedgehog, the player can get a few hits in before Mecha Sonic releases the wrecking ball. When playing as Sonic, the player can also hit the Egg Mobile-H from the ground by using the Insta-Shield, a Double Jump granted by the Lightning Shield or a Bound Jump granted by the Water Shield. When playing as Tails, the player can also hit the Egg Mobile-H by flying and can also avoid getting hit by the wrecking ball if they are careful enough during the flight.

After eight hits, the chain and wrecking ball are destroyed and Mecha Sonic escapes with the exploding Egg Mobile. A Warp Point will appear below the ground, allowing the player to progress to the next part of the level.

Sonic Advance

The Egg Mobile-H reappears in Sonic Advance. It is the first boss of X-Zone. Once again it is this time piloted by Eggman, with an appearance that has been taken directly from the original Sonic the Hedgehog. Eggman will fly down to the arena and then release the classic wrecking ball.

This battle is generally easier than the original Sonic the Hedgehog, as it only takes four hits to defeat Eggman. However, when playing with Amy Rose, the player has to perform the Hammer Jump technique in order to deal damage. Furthermore, the player is now unable to damage the Egg Mobile during its descent into the arena. After taking four hits, the chain and wrecking ball once again get destroyed while the defeated Eggman flies away.

Sonic the Hedgehog 4: Episode I

The Egg Mobile-H is the first boss of Sonic the Hedgehog 4: Episode I. It is piloted once again by Dr. Eggman in the boss act of Splash Hill Zone. Normally the battle takes place on similar wide arena with two platforms, where Eggman flies down with his Egg Mobile and releases the wrecking ball from the mobile. The first phase of the battle is identical to its previous appearances in past titles though like in Sonic Advance, the Egg Mobile cannot be damaged until the wrecking ball is fully deployed.

Upon taking five hits of damage, Eggman will utilize a new attack; he will retract the ball and flip 360 degrees, slamming it down where Sonic is. However, this also leaves him vulnerable as he retracts the wrecking ball in preparation of using this attack again. The most consistent way to avoid this attack is to stand close to a boundary while standing on a platform and jumping at the moment Eggman flips. Doing another four hits makes the wrecking ball and chain explode, causing Eggman to slowly escape with his Egg Mobile.

The vehicle later appears again in E.G.G. Station Zone, as part of the boss rush before the final boss. The only difference in that zone is that the platforms move up and down once the player jumps on them, which can make the battle slightly challenging. After receiving one hit, Eggman will then proceed to use the new attack. After hitting the Egg Mobile four times, the player moves on to the next boss of the zone.

  • The DD Wrecker from Sonic Mania is based on the Egg Mobile-H.
