Area Zero (エリアゼロ Eria Zero?) is a locale from Mega Man Zero 4. It is where the space colony Eurasia "crashed" a long time ago during the Maverick Wars (specifically, Mega Man X5), and nature slowly became abundant due to an environmental control system that was left active after the crash. Left alone even during the Elf Wars and cordoned off, it is one of the last habitable areas on Earth aside from Neo Arcadia. It was for this reason that a Caravan moved from Neo Arcadia to this location to escape from Dr. Weil's tyranny. Later, a mobile unit from the Resistance is stationed outside the area for protection. To leave humans without a place to escape, Dr. Weil initiates Operation Ragnarok, sending Craft and the Einherjar Eight Warriors to destroy Area Zero, though they are just a diversion
