* MadScientist: Weeny Pouchkinn, one of the [[CatPeople Katzen]]. He can be hero or villain depending on the timeline. In some timelines, he becomes TheHermit to conduct extremely dangerous research most governments won't allow. In this case, he will gladly join you if you let him in order to take a break from the tedium of unsuccessful TimeTravel experiments. In other timelines, he becomes EmperorScientist of the Katen, leads them into fallen empire hood, keeps them distracted with BreadAndCircuses, and becomes a crisis as he becomes a GodhoodSeeker. The good news is that his plans to AscendToAHigherPlaneOfExistence won't destroy the galaxy like an Aetherophasic Engine. The bad news is that it will still rewrite the hyperlanes and cause galaxywide earthquakes, resulting in severe societal disruption, not that he cares. Kaiser does not show up in the latter type of timeline.

*** ACOT also unlocks some higher tier giga structures, like upgrading the ludicrous monstrosity that is a Birch World into an even more ridiculous monstrosity called a Soul Birch World.

* {{Crossover}}: Gigastructures is designed to detect certain other mods and react to them to a certain degree. For example, with ''Ancient Cache of Technologies'', it unlocks higher difficulties where some of the custom empires get access to the technology defined by the other mod. While the events of other mods are not considered to be part of Gigastructures's default timeline, some cycles will include them, so Kaiser will still be familiar with their concepts.

* OverflowError: Stellaris mostly uses [[PowersOfTwoMinusOne 32 bit variables]]. Gigastructures is one of the stronger mods, and while it will not by itself cause an overflow error, synergizing it with certain other overpowered mods will give you numbers so high that they will overflow right into the negatives.

* KeystoneArmy: [[spoiler:The Blokkats have constructed themselves from an artificial form of matter. One that is extremely unstable without their infrastructure to back it. Destroy their mothership, and the relay that keeps them in one piece is disrupted, killing most of the Blokkats invading your galaxy.]]

* BringIt: Your empire's default response to the arrival of the Blokkats is a "[[OhCrap That isn't good]]", but if you have certain overpowered mods and activated the highest difficulty, where the Blokkats recognize your empire as an actual threat, your empire's response is a confident BringIt.

* MechanicalAbomination: The Blokkats are something like this, being made of uncountable numbers of attomachines that each have computational capacities comparable to planetary-scale computers. They were once beings of flesh, but went through the Synth ascension route via BrainUploading. Despite this, they have twisted artificial souls on par with gods due to SoulEating. Their objective is to [[spoiler: preserve their existence indefinitely by accumulating so much mass-energy they can propagate their civilization into future versions of the universe]]. They do this by dismantling entire galaxies, and even harvesting the vacuum energy constant.

** There is a chance of you encountering an abandoned "Square World", where the would-be ring has corners. How does it handle the uneven gravitational pressure? It uses a form of {{Unobtanium}} and some unique alien technology.

** [[spoiler:Kaiser is technically from the past, but since the multiverse is effectively in a semirandomized StableTimeLoop, he still counts, continually jumping to a specific historical time point.]]

* PuzzleBoss: The Blokkats. [[spoiler:Their ship is protected by a shield that is invincible against conventional technology. Their opponents need to figure out how to reverse-engineer enough of their tech to build a weapon capable of temporarily disrupting it.]]
