History Characters / Signalis

* {{Determinator}}: Despite being just a regular human, Isa is able to progress through Sierpinski quicker than Elster in her desperate search for Erika, somehow dodging all of the corrupted Replikas and obstacles blocking Elster's path.

* AmbiguousSituation: It's unclear who the [=LSTR=] unit mentioned in her journal is. While likely to be [=LSTR=]-S2301, who was requisitioned to Sierpinski just before the time loop, that the same journal also described [[her memories being merged with those of Ariane muddies the water further.]]

* PastLifeMemories: [[spoiler: Alina was a close friend for Elster's original neural pattern donor, who they served together with in the same unit on Vineta. Elster's Gestalt memoriess and Ariane's fascination with her is what brings Alina's construct in the current reality.]]

* DeadAllAlong: [[spoiler:Elster died aboard the Penrose, and her corpse can be found later in the game. The playable Elster is strongly implied to be [=LSTR-S2301=], the unit mentioned in Adler's journals whose memories are being overwritten by Ariane's bioresonance projecting her Elster onto her[[note]]The Spatz update cleared up the corrupted unit ID on the blue screen of death to be this unit serial number up until the false ending, after which it will change to 512 if the player died again[[/note]]. The theory is further supported by Adler specifically mentioning [=S2301=]'s orange chest plate, whereas the [=LSTR=] typically comes equipped with the white body armor according to their series overview document.]]

* TheNicknamer: While most replika are content to go by [[YouAreNumberSix abbreviated numerical designations]], Starlings seem to prefer proper nicknames for themselves, [[NomDeGuerre in the style of squadmates giving each-other evocative callsigns]]. The scoreboard in the shooting range names two Starlings as "Hunter" and "Tank", unlike the lone Storch on the list who goes by "Seven".

* DeadAllAlong: [[spoiler:Elster died aboard the Penrose, and her corpse can be found later in the game. Who the playable Elster is remains ambiguous, either another LSTR model whose memories are being overwritten by Ariane's bioresonance projecting her Elster onto her, or an outright construct created from that bioresonance and the warping of reality that is unfolding.]]

* SequentialBoss: As the FinalBoss of the game, Falke has ''six'' sequential phases, each one more difficult than the last due to her dealing more damage to Elster as the fight goes on, and the scarcity of resources during the later segments. Given that there are no checkpoints, dying at any phase of the battle means starting over from scratch.

* {{Irony}}: Adler is somehow BlessedWithSuck in the form of a RippleEffectProofMemory, with him being the only one on Sierpinski who can vividly recall the events of the previous {{Groundhog Day Loop}}s. This being from a line of Replikas who are known for being extremely AllergicToRoutine.

* OtherMeAnnoysMe: Stated in the briefing about known issues with the Adler model. Whereas most other Replika models get along at least among each other in the same model, Adlers don't, and only seem to respect Falkes.

* YouAreNumberSix: All Replika are identified by their model followed by a number code, like the protagonist being "LSTR-512". Some replikas mentioned in notes go as far as to adopt their numbers as a personal nickname, typically the last digit of their unit [=IDs=], such as a Storch called Sieben (Seven), and Aras referring to themselves as Fünf (Five) and Elf (Eleven). The Eule units are a notable exception to this with [[TheNicknamer their tendency to give each other nicknames.]]

* TemptingFate: A sane Starling you encounter early in the game states that she'll be leaving the building as soon as her repair patch heals her... when you renter the room later she is gone, leaving a blood stained floor behind and her unused repair patch. It's never revealed what exactly happened to her, but it probably wasn't good.

* YouAreNumberSix: All Replika are identified by their model followed by a number code, like the protagonist being "LSTR-512". Some replikas mentioned in notes go as far as to adopt their numbers as a personal nickname, typically the last digit of their unit IDs, such as a Storch called Sieben (Seven), and Aras referring to themselves as Fünf (Five) and Elf (Eleven).

* YouAreNumberSix: Implied to be the naming convention among Storches, who seemingly refer to themselves using the last digit of their unit ID. The "About the Administrator" note was penned by a Storch with serial code S-230'''7''', who refers to herself as "Sieben" (seven).

The player character, she is a Replika technician of the scouting starship Penrose-512 sent out to parts unknown to find new worlds for humanity to colonize.

* MightyGlacier: They boast a very beefy 200 HP, the highest of all non-boss enemies, and are armored in bulletproof plating to boot, while their mining lasers can quickly tear through Elster's health should they manage to get a few shots in. As a trade-off, their bulk makes them extremely cumbersome to move around, such that Elster can outpace them without sprinting, their laser cutters need to be slowly engaged and disengaged every time they attempt to shoot, and have to sit through several seconds of charging even then, making them easy to outmaneuver should the map allows for it.

* TheGoomba: Like the Eule, Aras are among the more common enemy types Elster can run into, and they almost always come in groups. To compensate, they also possess only a measly 30 HP[[note]]For comparison's sake, Eules have 35 base HP, while their mutated version countered during the latter half of the game has 50[[/note]], making them much easier to put down.
