** ''Nemesis'' allows the player to committ a ApocalypseHow/ClassX3 with the "Become the Crisis" path, where your civilization strives to become one with the Shroud by detonating every star in the galaxy. Along the way you'll also committ several ApocalypseHow/ClassX2 events by using Star-eaters to harvest the necessary resources.

** With ''Nemesis'', a civilization that has chosen to Become the Crisis will start building an Atherophasic Engine in their capital system. When activated, the Engine will annihilate all life in the galaxy. In order to activate it, it needs a stupendous amount of Dark Matter. To get that Dark Matter, the civilization also builds massive weapons that can implode stars to turn them into black holes. Of course, everything orbiting that star will be destroyed in the process.

** YOU may be the cause of this with the ''Become the Crisis'' ascension perk. When you finially generate enough crisis points to reach level 5, the ENTIRE galaxy (except any fallen empires) will declare war on you all at once.

** The ''Nemesis'' expansion adds a fourth crisis: ''you''. Yes, you can become the Final Boss -- or rather, face ''the entire galaxy'' as your own personal Final Boss. An ascension perk called "Become the Crisis" sets you on the path to {{galactic conque|ror}}st, the end goal being to build a DoomsdayDevice called the Aetherophasic Engine that will grant you absolute power but destroy the galaxy. Alternatively, if somebody else takes this path, you can become the Galactic Custodian who rallies the galaxy against this menace, facing them as the Final Boss.

* DysonSphere: One of the constructable megastructures in the ''Utopia'' expansion. Unlike many examples, it only encloses the star itself and not the entire solar system; however, it still takes a lot of time and resources to build and produces a ''massive'' amount of energy (up to 4,000 units, to be precise). They can only be constructed in systems without habitable planets and will freeze over any barren or molten worlds once construction is finished - which tends to happen when you ''block out the sun''.

*** [[TheEmpire The Imperium of Man]] doesn't even need to be built from scratch; one of the pre-built starter empires, the Commonwealth of Man, is a LostColony that is one part Imperium of Man, one part [[Film/StarshipTroopers United Citizen's Federation]]. Alternatively, the player can make an Authoritarian/Xenophobe/Spiritualist to get psykers and the Divine Cult civic for a proper God Emperor.

** Occasionally Caravaneers "mingling" with your people will result in the birth of hybrids, the flavor text reading "[[Creator/JeffGoldblum life, uh]]... [[Film/JurassicPark finds a way.]]"

** ''[[VillainProtagonist You]]'' can cause it too, by building Aetherophasic Engine, which will turn all stars in the galaxy into black holes, while your civilization will come to Shroud and become gods.
