Alien Conquest Alien Conquest is a Space theme released in May 2011 . The theme features a large invasion force of aliens attacking earth and attempting to steal all the brainpower from the humans , a first for LEGO . This is the first Space theme to use this premise , with preceding Space theme s involving astronauts battling aliens on other planets or meeting more friendly alien lifeforms , such as Martians . This was be the second line of set s released in 2011 with a Space ethos ; the other as a subtheme of City . The team of astronauts is known as the ADU , or " Alien Defence Unit " . Story . According to a comic in the November - December 2011 edition of LEGO Club Magazine , the story of Alien Conquest ties in with multiple themes . It is shown that the aliens first attempt at world domination was with the Atlantis Guardians , who are most likely alien in their nature themselves . Another attempt was when Alien Commander assisted Amset - Ra in creating the 5 Golden Treasures sought after in Pharaoh ' s Quest . However , after Amset - Ra was apprehended by Jake Raines and his crew , and the The Golden King was saved from the evil Atlantis Guardians , Commander Hypaxxus - 8 launched a full - scale attack on Earth , preparing to abduct all the humans , use their brains as fuel for their Solar - Galactic Batteries and enslave them as mindless zombies . However , when the ADU ( Alien Defense Unit ) is formed , the battle for the fate of the Earth begins . However , in the comic ' s climax , Hypaxxus unleashes his master plan - he first travels to the City of Atlantis and kidnaps the Golden King to use his 5 Trident Jewels as a source of power , and later goes back in time and rescues Amset - Ra , who joins him with the treasures . Together , the two of them planned to use the power to finally control the world , however they are once again upstaged when the ADU fights back and forces them to retreat . Thinking they were defeated yet again , Amset - Ra becomes furious at Hypaxxus - 8 for another failure . But he reveals he has another plan for world domination , which apparently , would tie in with the Dino theme , but they never expanded the story any further . Online games .
