And not even in a canon part in PU, either.
The game's very ending isn't canon?...
And what about Cossack's robots? We never see them back in "camp Cossack" again.
The Cossack family is completely different from the Right family in that Right appears in every game, Cossack vanished from the story long ago. Not to mention, Wily's involvement with the Cossack robots to the point that all were given combat upgrades by him and SkullMan/RingMan being his creation. Comparing the mm3 robots to mm1/9 and mm4/6, it is simply a complete break of pattern from other Right robots, making it that much more similar to the treatment of robots created by unimportant people and characters that vanished from the plot.
although it's fair to say he probably rebuilt them for legit uses. We never see Plant man or Centaurman used for his legit purposes. Does that mean, after MM6, he's never used for a legit purpose again?
I never said they weren't used for legit purposes ever again. They are all after all in the robot museum for some explicit purpose. I just said they are not considered part of the Right family. Cossack robots aren't considered part of their family either in later games, only in secondary sources. The mm3 robots don't even have those secondary sources. Four sources and a secondary source go toward mm1/9 being part of the family, Cossack gets a secondary source for his robots being part of his family, the mm3 robots don't have anything to link them to the family.
Also, how about addressing the matter of them being considered Wily numbers, not Right Numbers, despite being created by Dr. Right? Even the mm9 group were labeled DRN after so many DWN came before them. The only difference is whether Wily was involved at all, regardless of exact degree that he was.
SAR and PU.
Battle and Chase. GutsMan and IceMan are on Right's side. MM3 robots do not get any coverage except for ShadowMan. Also, mm9 is the fourth source to Right robots as part of the Right family.
It has nothing to do with whether they were made "mostly" by Wily or not. It proves nothing.
I already addressed this twice, I said it didn't apply to the 'degree on which Wily developed them', it applies to 'how they are treated by Capcom and the plot.'
Your ultimate point is moot. I said they were stolen ... you're not proving me wrong or poking holes in my statement at all by going on and on about how they're supposed to be "mostly Wily's." At this point you're just arguing for the sake of arguing.
You were talking about who created them, using the argument of 'they're stolen' to say they weren't created by him. Going on about whether or not they're stolen is something we've moved on from long ago: he's stealing his own creations. The initial point is: Wily made them or not, everything above is about a separate discussion whether they're considered to be more Wily's than Right's. Even in your edit of that initial post, you advocate Right as having more involvement than Wily. There's no statement who did more, who did less and if it's equal. Thus the above focuses solely on how they're considered, they're considered to be Wily Numbers.
Everything below here will not focus on that, rather, it'll cover the initial point of which robots Wily created.
It's a well established fact that 6 weren't his. I've never once seen someone say otherwise. For, 2, 3, and I just checked, even 5 (despite a possibility of splitting hairs with ChargeMan's entry), they would be absolutely correct that Wily made them. 7 and 8 are the only truly mixed bags in the entire series. In 4, we generally accept them as Cossack's, but SkullMan/Ringman is the exception, being Wily made. In 3, they're all Right and Wily cooperations, with the only exception being ShadowMan having no involvement from Dr. Right. mm1 and mm9 are two entire sets of Right robots.
If you want to talk about that particular fanon (Wily made all of the boss robots), it lies with mm7, 8, and the notion that Wily was Light's assistant before mm1. Not with mm3.
