Egg Mobile-H

The Eggmobile is the boss of the Green Hill Zone in Sonic the Hedgehog (16-bit). It is piloted by Doctor Eggman and equipped with a massive, checker-board pattern wrecking ball, that hangs suspended from its underside by a chain. This version of the Eggmobile is by far Eggman's most famous machine in the Sonic the Hedgehog series and has reappeared in many other games.

thumb|250px|left|The first appearance of the Eggmobile (wrecking ball) The battle takes place at the end of the third Act of the Green Hill Zone, on a flat piece of grass with two floating platforms above it. Eggman will fly back and forth across the screen, swinging the wrecking ball from side to side. To defeat him, Sonic must leap onto one of the floating platforms and then spin jump onto Eggman eight times. This will destroy the Eggmobile, as well as every link in the chain and the wrecking ball itself, and Eggman will flee, allowing Sonic to open the Egg Capsule and complete the level.

Sonic & Knuckles
The wrecking ball Eggmobile also appears as a boss in Sonic's story in the Sky Sanctuary Zone in Sonic & Knuckles, in which it is piloted by Mecha Sonic.

Sonic Advance
The wrecking ball Eggmobile appears, again piloted by Eggman, as a boss in the X Zone of Sonic Advance. This version takes only four hits to destroy.

Sonic the Hedgehog 4: Episode I
The wrecking ball Eggmobile is the first boss of Sonic the Hedgehog 4. Upon taking four hits of damage, Eggman, will pull up the ball and flip 360 degrees, swinging the wrecking ball and slamming it down where Sonic is. However, this also leaves him vulnerable as he retracts the wrecking ball to prepare for another attack.

Adventures of Sonic the Hedgehog
In the pilot episode, Doctor Robotnik tries to use the wrecking ball to defeat Sonic but fails. In the pilot, the wrecking ball is colored black and white.

Sonic the Comic
The wrecking ball Eggmobile also appeared in an early issue of Sonic the Comic. Doctor Robotnik piloted the wrecking ball Eggmobile after brainwashing Tails and turning him into the cyborg Robofox. Robotnik nearly defeated Sonic the Hedgehog, who had been caught unawares by Robofox, until Tails broke through the brainwashing and destroyed the Eggmobile with a powerful Spin Attack.

A group of badniks in the Marble Zone later had one of the checker-pattern wrecking balls (which they referred to merely as "one of [their] Master's weights"), which they threatened to use to crush the squirrel Tufftee.

Sonic the Hedgehog (comic series)
In the Sonic the Hedgehog comic series, the wrecking ball makes an appearance (under the moniker of "checker-wrecker ball") in the first story of the original miniseries as one of the the the things Robotnik tries to defeat Sonic the Hedgehog with. It backfires however, when Sonic uses a Power Ring to defeat Robotnik, causing the wrecking ball to crush his Egg-O-Matic.

It is later used by Snively in the Genesis arc after the world is reset by Eggman, but Sonic quickly disposes of it. .
