-There were supercool legendary superheroes. ("The olden days." According to Chris' daddy, there used to be supercool legendary superheroes. But that was long, long ago, so there aren't many pictures of them left. One depicted example legendary superhero is the MegaMan from the first game's american boxart.This legendary hero looks more like a coalminer, like the other legendary heroes in that image collection.)
-Rockman and Forte: Challenger from the future (The adventures of an unlikely hero, a walking stove, Konroman, are told of in the comic about Ray's favorite superhero. Konroman fights MegaMan in the comic.)

-Prairie got a Stuffed Animal from the First Commander which she treasures.
-The First Commander, a human scientist protected Reploids when no-one else would.
-The Satellite Cannon Ragnarok was destroyed by the Legendary Red hero and its remains scattered across the world.

->
X^X AD
Albert creates Prometheus (DAN-001) and Pandora (DAN-002.) as children. They are intended to search for the Chosen Ones. Upon maturing each are embedded with Model W Biometal fragments and
forced to transform, incapable of turning back to their original forms. At the time of being viewed by Grey/Ashe, Prometheus' lifespan was 246929 seconds, Pandora 246939 seconds, until the next readjustment. This is their activity time limit that was remaining, not their maximum activity time limit. They are to return to their capsule before their time is up to restore their lifespan or they die. Serving as the chains that bind them. (This does not specify their time of creation. But they have been active for multiple hundred years before ZX. Prometheus has met Albert centuries before ZXA, details are scarce, but there is one reported case of Albert appearing on a monitor.)

(Aile was separated from her mom during the panic and Giro was the one that found and rescued her.) The Mavericks involved in that raid were searching for the Chosen Ones that would become the perfect vessel for Model W, they allowed only the Chosen Ones to live. Purprill the Mandroid was the Maverick commanding this attack. Soon after Serpent enlisted him as one of his executive officers and turned him into a Pseudoroid. (Vent/Aile are age 3, 4.)
->

Other notable events:
-The death of Rose's boyfriend; He was caught in a Maverick raid. He suffered for two days before finally dying. Thanks to this tragedy, Rose decided to become a nurse.
-The great great great great great great grandfather of Lucia, the human girl who sells you bread used to work in a village bakery. He learned his secret recipe for making delicious bread from an old Reploid.
-Model A's creation occurred a long time ago, but after the creation of Model V and Ciel's BioMetals. It is left behind in ruins for the Chosen One that would carry on his plans: Grey.
-The Hunter's Guild was established centuries before ZXA, after the fall of Neo Arcadia and the 2 year peace period. They discovered the Ice Darts hermit crab mechaniloid during that time frame.
-Soundsketch: Grey Capsule occurs anytime before ZXA and seemingly covers multiple time periods. Among other things, Pandora and Prometheus are discussing "Codename: Grey" and him being Albert's spare.
-Grey's creation postdates Model A's or occurred at approximately the same time. (14 years before ZX + Cold Sleep + Reploid Age Uncertainty.)
-Long ago the world was thrown into terror by Crickaleap mechaniloids. An outbreak of the hoppers resulted in hundreds of casualties and they have been much feared ever since.
-Atlas's country was destroyed by Mavericks.
-Siarnaq was left for dead by his Hunter comrades.
Notes:
-Humans and Reploids alike are unaware of the existence as Cyber-Elves. They have disappeared.
-Both Human and Reploids are turned into elves upon death through means seemingly related to Model W.
-The package Giro Express is ordered to transport is both Model X and Model Z. However, only Model X has recently been discovered. Model Z has been in Giro's possession for some time.
-The equality laws allow humans to be given Machine Bodies for the sake of an extended lifespan and durability after a certain age. Humans that have been given machine bodies are given a collation ID - a Hu Number (Hu meaning Human) - to indicate their flesh body's retention. Reploids are allowed to have human mortality, finite lifespans, which are activated the moment the Electronic Brain is. Those people originally Reploid are marked with a triangle on their forehead.
-The Sage Trinity (Three Wise Men) have lived for several hundred years and were originally human. They've expanded their lives by making use of Machine Bodies.
-Old Model Reploids seem to have no triangle marking to distinguish them from humans. But their lifespan settings are the same as any other. Prairie is not considered an old model Reploid, her marking is hidden under the hat she wears.
-Siarnaq, the Model P Mega Man was formerly a Hunter as an assassin. Ashe does not appear to know him.
-Atlas, the Model F MegaMan was a military member of a dead country destroyed by Mavericks.
-Ashe is a descendant of Albert's from the family he left behind when he was still human.
-When Model A was created, ciphers were placed within him. These ciphers would unlock as Model A gained combat data. Subsequently all information of Albert's plans would be relayed to the Model A MegaMan. Intended to mimic Albert's abilities of True A-Trans which comes from Model W, Model A has the ability of A-trans. Though Albert named Model A as Model Albert after himself, the issue of the consciousness within the BioMetal is not adressed. It might or might not be the S-class Maverick Hunter Axl.
-It is uncertain whether or not the given age of Reploids matches its actual lifespan or whether it is simply appearance/personality age only. Furthermore, whilst certain Reploids start their life as children, not all Repliroids do. This uncertainty mostly affects Girouette and Grey's given age. The uncertainty of Grey's age is furthermore affected by a lack of aging whilst in Cold Sleep.
-Grey was intended as the Model A MegaMan. Albert's back up existence. In case Albert was ever defeated, Grey would take his place on the world's throne. He has no established life prior to becoming an experiment as he's DAN-003, a creation of Albert's.
-Though the 4 were given Biometals after the events of MegaMan ZX, their time in Cold Sleep is unknown.
-Giroutte Express as a company was created as part of Guardian to cover up Girouette's identity as a Chosen One. Employees and clients are unaware of Girouette's ties to Guardian. Girouette Express was established any time in Giro's lifetime before the Cinq Ville Area H (Amusement Park) attack, after he had acquired Model Z and as a result of him being seen by Prairie wielding the Model Z. Prairie finally understood the reason for the order to protect raid survivors given by the First Commander and Girouette Express was established to enact this order. It is not clear whether Girouette was a Guardian before that one raid where Prairie witnessed him with the Model Z.
-It is uncertain when Slither Inc was first established by Serpent except that it most certainly postdates the destruction of Neo Arcadia and the 2 year peace period. It is however something he could have had even during his time as a Guardian. During the Cinq Ville crisis, his company was already around to step up against the Mavericks. It should be made clear that the Mavericks were a big factor in the energy crisis and that issue was mostly solved by force against the Mavericks through the establishing of a security force by Serpent. It is furthermore the case that his company seemingly employs System C.I.E.L. on grand scale. The system is also seemingly demonstrated in the Guardian's Grand Nuage, Guardian Base. Legion's Sage Trinity has not given it special mention during the revisit to Slither Inc HQ in ZXA and usage of the system should probably be seen as something normal.
-Vent and Aile both exist together within the universe of the ZX-series. However, there is a case of "same world's different story." In other words, two different stories are told in the world of ZX. In Vent's story, Vent and Aile both work at Girouette Express and by chance Vent is brought along with Girouette starting the events of the first ZX game, Aile is left behind at Girouette Express. In Aile's story, it is exactly the opposite. Vent's story then leads into Ashe's story where she acquires the Model A and Aile's story leads into Grey's Story. Regardless of whose story you are playing, these characters all exist together, all are Chosen Ones that have the potential to be Mega Men and their backstories have all happened. It is just that when Vent is a Mega Man, Aile can't be one. It is the same for the relation between Grey and Ashe, for them their respective intro stages are completed and the split happeneds when one becomes a Mega Man instead of the other. In the cases of an event being reliant on one of these 4 being a Mega Man that event is designated as belonging to either the Vent/Ashe Story or the Aile/Grey Story. However, it should be made clear that an event exclusive to one story probably has a counterpart in the other story. The ZX Anime Commercial proposes a third alternative story, where both Vent and Aile become a MegaMan, this is however not accepted in game canon.
Oddities:
-Giro acts as if the transformation is a first toward Vent. To Aile however he makes no such implication and refers to Model Z as his partner. By also noting that Aile doesn't know how to fight, he indirectly implies he does know how to fight, especially with a BioMetal. The truth is revealed in ZX Tunes; he had Model Z from the start. He lied to Vent, production staff theorize this is because of the different feelings he holds for Aile compared to Vent.
-Many characters refer to the events of Zero4 as hundreds of years ago. Model L only refers to it as a hundred years ago, a mistranslation, she too refers to multiple hundred years. Furthermore, an interview with ZX's producer reveals ZX is actually 200 years after ZERO, despite this not being stated explicitly in the game. Thus making all potential other single hundred year entries incorrect.
-A great wartime cameraman with unspecified gender is mentioned in ZX. This probably Neige from ZERO4. However, the English game refers to this person as male whilst the Japanese game is gender ambiguous on the matter.
-It is said that the BioMetal Model X was left behind by the First Commander after she made it. The mission description for the Model P pseudoroid Protectos however reads that this area is a lab with a similar layout to the one where the first commander "discovered" Model X. It seems to be the case that the Guardians at that point in the game assumed First Commander was the one that discovered the Biometals because they were unaware of the creator, it's only later revealed that the First Commander created them.
