Eurasia

The space colony Eurasia played a very important role in Mega Man X5 and Mega Man X6. In Mega Man X5, Sigma ordered Dynamo to spread a virus in the colony and make it crash on Earth, and the Maverick Hunters attempt to destroy the colony before it happens. Depending of the game events, the colony can be either destroyed before entering Earth, or crash and spread the virus. In Mega Man X6, it's shown the colony had fallen. Gate explored the remains of the colony in its crash site and found of a fragment of Zero, which passed the virus to him and made him Maverick. In Mega Man Zero 4, it's revealed Area Zero is the local where Eurasia had crashed.
