History WMG / NieR

* Sadly jossed. Tyrann is a former Japanese soldier known for getting results rather brutally. Also, had Tyrann actually been Caim, they'd have probably gotten his voice actor back to maintain continuity.

[[WMG: The Black Flower is the original Emil]] Grimoire Noir and Grimoire Weiss merging may have had something relating to Zero's Mechanical Flower.
Mikhail and Michael seem connected

* Nah, Cavia' world is too messed up even for Goddess!Madoka.

The nature of Nier's self-RetGone isn't made entirely clear, but we know that he has indeed left traces of himself behind - Yonah herself couldn't really exist if Nier never existed (what with him being her father) and Kaine still gets to keep her Lunar Tear, and even remembers that it holds some sort of significance to her.

Furthermore, Yonah kept a diary which frequently mentions her father, and at least one entry explicitly mentions that her father knew Kaine, so the two of them can draw the conclusion that this hole in their memories is probably related to Yonah's father. Of course, this assumes that the diary remains intact, but even without it the fact that Kaine came to rescue Yonah ought to make them both aware that they are linked somehow.

Adding Emil into the mix makes it even more likely that they'll be able to piece some things together. Nier was instrumental in Emil's transformation, and his butler sent that letter to Nier before then - so without the memory of Nier, he will too need to search for an explanation for how those things came to pass. Since he clearly remembers Kaine and is trying to meet up with her, this reinforces the notion that they might go on a quest to figure out what happened to their memories.

At the very least, I think that Kaine and Emil (and possibly Yonah, depending on how healthy she is) will go on a quest for answers, and considering what an impact Nier had on the world, I would be surprised if they couldn't find at least a few. Perhaps their memories alone won't be enough to call him back (this IS a Cavia game, after all), but I nonetheless think that Nier's RetGone is not as final as it appears.

** And Caim wasn't a japanese soldier known for getting results rather brutally?

In the first scenario, Father Nier and his wife died, leaving Brother Nier and Yonah as orphans. As the game progressed, Brother Nier sacrificed his existence to save [[spoiler:Kaine]]. Because he was erased, his birth never happened in the second scenario, making Yonah the only child and changing his father's fate (his mother still dies, but his father survives). Thus, the Nier of ''Gestalt'' takes over the role of Neir of ''Replicant''. And when it comes to [[spoiler:either sacrificing Kaine or saving her]], it's most likely that this Nier performed a MercyKill on [[spoiler:Kaine]] instead what his long-forgotten son did in the previous life. Though, there may be some little chances that father Nier might sacrifice himself, thus the cycle continues and history repeats itself.

* WordOfGod confirmed that the protagonist of ''Nier: Automata'' is in fact a [[ActionGirl combat]] [[RobotGirl android]] known as YoHRa "2B". They ''do'' share many similarities, don't they?

[[WMG: The remake will have Callbacks to Drakengard 1 and 3, as well as a Callforward to Automata]]
