The Eggrobo (エッグロボ Eggurobo?), also spelt EggRobo[2] or Egg Robo,[3] and also known as the Eggman Robo[1] (エッグマンロボ[1] Eggumanrobo?), is a character that appears in the Sonic the Hedgehog series. It is a mass-produced Badnik model based on their creator, Dr. Eggman. In addition to being powerful soldiers on the battlefield, the Eggrobos are smart-bots designed to carry out tasks in Eggman's stead, making them a crown jewel in Eggman's attack force.[5]


The Eggrobos are fully egg-shaped humanoid Badniks, based on Dr. Eggman's likeness. Their middle torso is red with yellow downward-pointing triangles on the front while their lower torso is black with two silver buttons on the front, making their design resemble Eggman's attire from the pre-Dreamcast era. Their gray head area is clean with two small red eyes and a flat jaw fastened by yellow bolts. On their back they have two yellow and gray rockets for flight. They also have thin robotic arms and legs with round shoulders, white gloves and black shoes with white straps.

Since Sonic Generations, the Eggrobos' design became more detailed. In the same game, a different colored version of the Eggrobo appeared. These variations have complete black and gray torsos with red cape-markings and hatches on their head.

Game appearances

Sonic the Hedgehog 3 & Knuckles


In Sonic's storyline of Sonic & Knuckles and the lock-on game, Sonic the Hedgehog 3 & Knuckles, Eggrobos appear as standard enemies in Sky Sanctuary Zone where they are launched from the Death Egg. In gameplay, they hover in one place and shoot lasers from their pistols. Sometimes, they also emerge from towers with Animals escaping in their wake. The player can easily defeat them with a Spin Jump.

An Eggrobo has a more prominent role in the Knuckles' storyline of Sonic & Knuckles and Sonic the Hedgehog 3 & Knuckles. Accordingly, it was sent by Dr. Eggman to eliminate the echidna, whom Eggman had deemed a potential threat.[6] As Knuckles relaxed in the Mushroom Hill Zone, the Eggrobo dropped a bomb near him, but only made the Animals run away. Enraged, Knuckles sets off to defeat the Eggrobo.[6]

It is also implied that the Eggrobo in Knuckles' story is the same one that appeared in Sonic's imperfect ending (if the Super Emeralds are not collected), implying that this Eggrobo survived the Death Egg's destruction.

From there, the Eggrobo replaces Dr. Eggman amongst the bosses in every Zone up until the Hidden Palace Zone, excluding Flying Battery Zone.[note 1] These boss battles with the Eggrobo are more challenging and have alternate attack patterns. The Eggrobo was destroyed by Mecha Sonic in the Sky Sanctuary Zone when Knuckles escaped the Eggrobo's restraints just as Mecha Sonic charged at him, causing Mecha Sonic to destroy the Eggrobo and the Egg Mobile instead.

Sonic R

In Sonic R, an Eggrobo, named Eggman Robo[1] (エッグマンロボ[1] Eggumanrobo?), appears as an unlockable character. It is unlocked by getting all of the five Sonic Tokens on the Regal Ruin course.

In gameplay, the Eggman Robo has most of the abilities Dr. Robotnik has, being able to fire Homing Missiles and hover across water, albeit only for about three seconds. Though it is a bit slow and clunky, it has superior cornering ability.

Sonic Adventure 2

In the original Dreamcast version of Sonic Adventure 2, the Eggrobo, under the name Egg Robo,[4] could be downloaded as a playable character for use in the Kart Racing mini-game, along with a new course, titled the "Egg Robo" Course.[4]

In Sonic Adventure 2: Battle and the 2012 remaster, the Egg Robo could be unlocked in the racing minigame by clearing all of Rouge the Bat's missions. However, it was not part of the game's actual story or any normal stages.

Sonic Chronicles: The Dark Brotherhood

In Sonic Chronicles: The Dark Brotherhood, a non-functioning Eggrobo is found lying around next to a Sega Mega Drive and a Capsule in Metropolis.

Sonic Generations

In the console/PC version of Sonic Generations, Eggrobos from somewhere across spacetime appear as enemies in Sky Sanctuary. Like in Sonic & Knuckles, they are launched from the rising Death Egg, as seen in Sky Sanctuary Act 1. Their attack pattern is relatively the same as in Sonic & Knuckles, but they do not contain any Animals.

The game introduces a darker variation of Eggrobos in Sky Sanctuary Act 2 and several Challenge Acts which missiles from their head that home in on the player, although these missiles are rather slow. A regular Eggrobo statue can also be unlocked in the Statue Room.

Sonic & All-Stars Racing Transformed

In Sonic & All-Stars Racing Transformed, Eggrobos make an appearance on the Sanctuary Falls track, which itself is based on the Sky Sanctuary Zone from Sonic & Knuckles. In this track, Eggrobos appear as both an obstacle and as a standard enemy like in their debut.

Super Smash Bros. for Nintendo 3DS

In Super Smash Bros. for Nintendo 3DS, the Eggrobos appear as common enemies in Smash Run. Unlike the original games, Eggrobos move around while in flight, and can fire their blaster at their targeted player.[7] In addition to Smash Run, it also appears as a trophy:

Mario & Sonic at the Olympic Games Tokyo 2020

In the Nintendo Switch version of Mario & Sonic at the Olympic Games Tokyo 2020, the Eggrobos appear as playable characters in the Volleyball 2D Event. During this event, the Eggrobos serve as Dr. Eggman's teammates. Notably, the Eggroboss possess their 16-bit sprite appearance from Sonic & Knuckles, albeit with some slight modifications.

Powers and abilities

The Eggrobos were intended to be the strongest of Dr. Eggman's robots, including Metal Sonic and Metal Knuckles, but failed to live up to the doctor's expectations.[5] Eggman also boasts of the offensive abilities he gave them, suggesting they pack lots of firepower.[5]

All Eggrobos are capable of flight using their rockets. However, their true strength lies in their design which minimizes air resistance, allowing them to move at speeds matching even Metal Sonic's.[5] Black variations of Eggrobos see during the Time Eater incident can also launch rockets from their heads.


The standard Eggrobos' primary weapons are singular energy beam pistols, which they wield at all times. These pistols can shoot long-ranged neon-colored lasers.

In other media

Sonic the Comic

An EggRobo, from Sonic the Comic #49.

An army of EggRobos appeared in the Sonic the Comic series published by Fleetway Editions' adaptation of Sonic & Knuckles. In this series, the EggRobos could be controlled directly by Robotnik from his control room aboard the Death Egg II. Each model had cameras fitted into its eyes, allowing Robotnik to see everything, and a voice synthesizer allowed the doctor to communicate directly via the robots.[8] EggRobos could also function as regular Badniks without Robotnik's direct control.[9][10]

Archie Comics

Julian Snively stuck in a broken Eggbot, from Sonic Super Digest #12.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Eggrobos were built by Snively Robotnik to be part of his own private army. They were intended to be used against Snively's uncle, Doctor Robotnik, and instead assist Snively in taking over Mobius himself. Although Snively referred to them as "EggRobos" in their first appearance, Antoine D'Coolette later called them "Eggbots," which was the name used in all subsequent appearances.

Following the Super Genesis Wave, the Eggbots' history has become nearly identical to their game counterparts'.

In celebration of the twentieth anniversary of the Sonic series, Jazwares produced a 3-pack of 3" action figures with Classic Eggman and two Eggrobos.



  1. During the boss battle of Flying Battery Zone Act 2 as Knuckles, Dr. Eggman is piloting the Hang Mobile instead of an Eggrobo. No reason is known for this, but it is presumably due the lack of separated in-game sprites of Eggrobo for the vehicle.
