Since when does the region a work is released in matter in terms of canon? By this logic Rockman & Forte wasn't canon until it was released in the US. That just doesn't make any sense. A work isn't excluded from canon just because it wasn't released in your region.
When the country of origin isnt getting it, and coupled with the fact that it is an outsourced game that splits from the conventional path of the timeline, and does the crazy shit RO does, until further word on it, it is assumed not canon to the games and their timeline. But like I said, since it branches off into it's own branch, its irrelevant either way.
Also, there hasn't been any confirmation that MMOnline splits into a different timeline AFAIK.
it is specifically stated to take place centuries after X and Zero are dead, in this odd Military/research station thing called "Gaia" which the trailers show us, is this large spherical structure in space connected via what may or may not be an orbital elevator- to the earth.
The Maverick threat also has dissaeared, so when one day mavericks based on reploids (and robots) from the past appear, they make clones of the good guys to deal with it. going so far as to embet their DNA within them to make them authentic as they can. (how they got Duo's DNA is anyone's guess)
Which means it is long after the X series, and yet it only encompasses Classic and X series characters. That, and Cinnamon has visions of "Neo Arcadia". Which would already suggest that it is a parallel timeline where the X series instead lead to Online, and Cinnamon is having visions of the other timeline.
And there is absolutely nowhere to place it in the current timeline where it would make sense.
there is only 1 century from X to Zero, and 200 from Zero to ZX. 200 years in which reploids have peacefully coexisted with Humans due to the laws of equality passed by the Sage trinity. (and after Neo Arcadia was nuked from orbit by Kraft)
The designs also correspond to the Classic and X series designs. No Zero and on designs involved.
It's not that they aren't recognized, they aren't mentioned at all. Not being mentioned in a resource book is not grounds for exclusion from canon. Until CAPCOM says they're not canon there's no logical reason to exclude them unless you want a separate canon for each region and there's no indication that CAPCOM intends this.
Capcom has other things to do other than hold press conferences over "this is canon, that isnt". Its up to us fans to use common sense and logic to figure that out. Not everything with the name Mega Man is canon to the games and their timeline.
Why is it we do not consider the Brazilian Mega Man comics canon then? by that logic, since they are licensed by Capcom, they should be. Just like those 2 games.
