Aliens is a term collectively designating the extraterrestrial enemy force occupying Earth in 2035 under the veneer of ADVENT, a puppet administration chaired by members of the former Council. As the main antagonists and enemies in XCOM 2 and XCOM 2: War of the Chosen, they feature significant improvements brought on by the integration of human DNA. Having enthralled most of the human population, they wield a dominating global presence in the name of the "Elders," whose true goals are unknown.
