History Fridge / ChronoTrigger

** 12 million BC: It slows you down (like what was intended to do here) and the centre part is more aggressive - because it almost woke up at this time.

** Considering how AnotherEden, the SpiritualSuccessor of the Chrono series headed by the lead writer also has an abundance of cats being deeply related to time travel, that might be some sort of in-joke or signature of Kato's... Heck, his name even sounds like how a person with a Japanese accent would say "cat".

** Atropos only says this when she's been reprogrammed by Mother Brain and is trying to convince Robo to side with her, and as for the other R-Series, they're security bots so it makes sense that they would think that dealing with intruders is their entire reason to exist. It's easy to summise that Atropos is lying at that point given how she acts when she's briefly in her right mind.

** 2300 AD: The ultimate magic. Wait, why would it use it here instead of in the age of magic? Well obviously it's using things from the age of technology... meaning it's using energy attacks. Which is basically what magic is - Using energy attacks .

* The relative capabilities of items created in various eras; 1000 AD < 600 AD < 2300 AD < 65,000,000 BC < 12,000 BC. The Present is in peacetime, the Middle Ages is at war, the Future is post-apocalyptic(and possibly practices planned obsolescence), Prehistory has a prevalence of [[{{Unobtanium}} Dreamstone]], and Antiquity is ruled by AdvancedAncientHumans and in fact the single most advanced era Crono and the gang visit.

* After Lavos devastates the world in 12,000 AD, the world and the humans in it eventually recover, picks themselves up, and the world is fine in a few thousand years. However, in 1999 AD Lavos devastates the world and a few centuries later in 2300 AD the humans are barely surviving rather than working to rebuild civilization again. There's a number of factors that give the differences:

* When Crono and company fight Lavos in the Ocean Palace 12,000 BC it's shell is stronger than it is when fighting it in 1999 AD, despite how lore on Lavos in game indicates that it should become stronger as it sleeps instead of weaker. However, in 12,000 BC Lavos isn't truly waking up to begin it's spawn cycle, it's simply getting up for a bit to smash an annoying irritant and going back to sleep. In 1999 AD however Lavos is waking up and preparing to spawn, thus it is likely pushing some of it's power over to beginning this process and as such is weaker than it otherwise would be.

*** According to the ''[[AllThereInTheManual Chrono Cross Ultimania]]'', the odds of another Time Devourer being made are even lower than described above. The intact person thrown into the Darkness Beyond Time can't just be any random person, they need to be an Arbiter, someone who has had their biology altered by direct, personal contact with the Frozen Flame. Schala was an Arbiter, thus why she was responsible for using the Mammon Machine. Even then, one Arbiter isn't enough. The Time Devourer wasn't going to achieve it's final, reality-ending form until it absorbed a second Arbiter, in this case Serge. The odds of two separate Arbiters being thrown intact into the Darkness Beyond Time alongside a retgoned Lavos being are so astronomically low it's not even worth considering.

* On the topic of mutants, the player only sees mutants in 2 areas, the Black Omen, and various 2300 AD ruins, which even has two "Mutant" enemies that are seemingly the same despite massive differences in strength. This is likely the result of creatures being mutated by the presence of Lavos' power in the Black Omen, and by it's awakening spreading it's power over the entire Earth. Since Lavos is shown to force evolution in the life on a planet in order to strengthen them in order to improve itself better, this makes sense, even though in the latter case it doesn't need to do so anymore simply being exposed to it's power for extended periods will do it.

** Atropos only says this when she's been reprogrammed by Mother Brain and is trying to convince Robo to side with her, and as for the other R-Series, they're security bots so it's makes sense that they would think that dealing with intruders is their entire reason to exist. It's easy to summise that Atropos is lying at that point given how she acts when she's briefly in her right mind.

* It seems weird that the Fiendlord himself can freely walk around 600 A.D. and even visit Guardia's royal family without anyone recognizing him... Unless what he really looked like wasn't common knowledge in human society, which is not unthinkable in the middle ages. They probably expected the Mystics' leader to be appropriately monstrous rather than being a somewhat unusual but mostly normal-looking man.

* When the Ocean Palace collapses, Schala tells the party she only has enough power left in her pendant to teleport them out, and not herself. However, an observant player will note that the Mammon Machine is still operational, and could easily charge her pendant just as it did with Marle's (or she could just, you know, borrow Marle's.) So why not just do that? Simple: This wasn't an act of [[heroicsacrifice sacrifice]] - it was [[driventosuicide suicide.]] Both Radical Dreamers and later Chrono Cross confirm that she wanted nothing more than to die afterward, and this contributed towards her being absorbed into the Time Devourer in Chrono Cross.

** TruthInTelevision. In RealLife, often TheMole could face danger from his own side, who would be kept in the dark as to his loyalties, or would even have to kill members of his own side to maintain his cover.

*** Besides which, the pendant and the amulet are seperate objects. At no point did Janus every have Schala's pendant. The Amulet is the metal object seen hanging from Magus's hip in official artwork.

- The Lavos devastation actually benefited the "Earthbound Ones" by ending the perpetual Ice Age, while the 1999 AD devastation appears to have caused a perpetual Ice Age.

- The 1999 AD humans were living in a highly advanced technological society as a whole as opposed to the Zeal society which were split up into the Zeal people and the Earthbound ones. The 1999 AD people were used to the machines doing all their work for them and thus there were few if anyone left alive that knew how to live off the land properly even despite a lack of much if any sunlight. The 12,000 Earthbound ones were used to scrapping by with whatever they could get and getting food, clothing and shelter even with a constant blizzard outside and the conditions had actually improved for them, so they could survive well enough after the devastation that they could even carry and teach some of the Zeal survivors.

- The 1999 AD humans have to contend with homicidal robots, mutant creatures, and a genocidal supercomputer specifically out to eradicate them.

So, overall the 12,000 BC humans had it much easier than the 1999 AD humans did.

* In Frog's ending [[spoiler: Frog ries Queen Leene. What happened to King Guardia XXI? Whatever happened to him it's different than the original timeline. Leene hadn't had any children yet, as the ending shows all of her descendants are half frog. This means someone in the party went back and removed King Guardia XXI, presumably so that Frog could marry her.]]
