Egg Mars (エッグマーズ Eggumāzu?) is a character that appears in the anime series Sonic X. It is a large robot made by Doctor Eggman.



Metarex Saga

The Egg Mars was initially piloted by Decoe and Bocoe to save Eggman after his attempt to deceive Knuckles and obtain one of the Chaos Emeralds failed. He briefly attempted to use the Egg Mars to force the heroes to turn the Emerald over to him, only for Metarex Jumpee to appear to claim the jewel. Despite the Egg Mars' superior size, it proved no match for the Metarex and was destroyed.[1]

Powers and abilities

Egg Mars demonstrated incredible size, strength, and durability. It could bury itself completely under desert sands and emerge within seconds, lift people with ease, briefly wrestle with Metarex Jumpee, and withstand getting thrown around by Metarex Jumpee. Should its sheer size and strength fail it, Egg Mars was equipped with a massive drill hidden its arm and a giant sword concealed in its back.


Egg Mars can easily be destroyed by an electrical overload.


  • The Egg Mars was likely named and modelled after the mech God Mars from the 1981 show Six God Combination Godmars, following on other classic mecha references in Sonic X.
