1.-Real proof of zero's death (painful as it is for me T_T)
ZX gives the proof; Zero is Model Z. Likewise, Zero was not seen 2 years after ZERO4, nor 200 years for that matter.
2.-How ciel came up with the whole biometal thing (like, if she converted the reploids into bio metals, or just took their DNA or whatever). I know they explain a little in ZX but not the WHOLE thing.
She analyzed Model V and used the
souls of legendary heroes.
3.-The whereabouts of Harpuia, Leviathan and Fefnir
Explained in MMZOCW and ZX; they died in ZERO3 and are now Model H, Model L and Model F.
4.-Real proof of X's death (T_T)
After ZERO3 X continued to exist as a Cyber Elf with very limited real world interaction; see Nakayama fanservice artwork. Eventually he became Model X.
5.-Link from MMX5-X6? to MMZero (assuming that X7 and X8 arent story related, X5 was the last "official")
Zero Collection cites
X6 as the link between series, MMZOCW further elaborates on this in great detail; we know the entire situation with very little gaps in information. The matter of X7, X8 and XCM is not to be addressed by the ZERO series. It is the X-series' job to ensure its own integrity within the established mythology.
6.-And also the link between MMZero and MMZX
The link between ZERO and ZX was explained in unprecedented depth in the first ZX title. As a result, it is actually the exact opposite of a plothole.
1.-So, youre telling me that Albert find the way to interact with the after life, so he could bring weil's soul back?
Model V is the fragments of Ragnarok that contain Dr. Vile's soul, altered by Albert to create Livemetal. It is the result of Dr. Vile's fusion with the sattelite cannon.
And 200 years passed from MMZero 4 to MMZX? (i must have amnesia i better go to play again), but asuming so,
"Centuries". Mentioned to be 200 years in interview.
how come praire is ciel's sister?
Though Prairie has the red triangle of a Repliroid under the equality laws, lifespans limited Repliroids can live just as long as humans. By use of machine bodies, humans can live for centuries.
5.-I meant that according to Inafume, MMX5 is the last game in the X's series, so X6, X7, and X8 arent really story related, cause he stop working in the following games.
Inafune is by origin a "character designer", his job is not "writer" or "scenario". He only took on a scenario/writer role with X, and even then he was limited by his superior and always gladly accepted input for his colleagues; especially in his days as producer did he leave the story up to the imagination of others. Remember that Rockman is and will always be a team effort; "Capcom" is the author, not any single member of the team.
And what happened to the mother elf?
One of the true plotholes left by ZERO4.
The best example i can give you is MM9 and MM10, you CANT possibly say that those games are canon
You should know that the producer of Rockman9 and 10 is Keiji Inafune and the production crew is Inticreates, of Rockman Zero and ZX fame.
Furthermore, how much a title adds to the overall story is not at all a measure for
canon, it is only a measure of
importance. In that regard, even its not immediately clear from the story itself, those titles actually hold a lot of secret recognition within the plot as envisioned by Inti staff. After all, when they made Zero Collection, Rockman10 was cleverly used by Inticreates to further justify and connect the plotlines of the X and ZERO series to that of classic.
