Mars (also known as the Outer Colony) is a futuristic city in the year 2060 and under the protection of The Great Defender.


Koza'Rai banished Egon Spengler to the future where Mars was now a colonized city. The look of Mars matched the bold predictions of Dr. Slausow in his 1932 work "Quantum Futuristics." The city was sealed by a protective sphere and came equipped with advances in technology such as moving sidewalks and jet packs. However, the effects of time displacement turned Egon into a megalomaniac. He automated the colony's defenses, armed his own team of guardsmen, and initiated a police state, all in order to protect Mars from assaults from waves of Exploding Manifestations.
