How can Riku being a party member be non-canon? He fought with Sora against Xemnas and was a key element in many events that happened in the world that never was. I can accept that Nomura may not have known about it until last minute but obvious his knowledge does not make or break cannon, KH is a group project with many members and writers, not just the will of one man. If you can provide a link which says that Rikus presence is non-cannon I will accept it but until then...
Actually, Nomura knowing or not knowing about something being put in-game makes or breaks canon, since it means whether or not what they developed was approved by him. The LS isn't canon because Nomura never told them what to do with the fight.
The same goes with Riku being in the party. His limits and reaction commands for better or worse weren't under Nomura's supervision, hence
It's more so the limit that's noncanon to me.
This is what I meant.
The Lingering Sentiment as well was
there, otherwise how could his
words be
yes canon? Words don't just appear out of nowhere, someone had to have said them. Hence why I consider the LS being there canon.
However, what took place in his fight with Sora, and the fight as a whole, are probably non-canon - because unlike the words the LS spoke, Nomura never gave the fight credibility, and in fact even lowered the entire thing's importance by saying it didn't matter whether or not that was really Terra - which means it wasn't.
Riku was there in TWTNW. He fought with Sora as I'm certain Mickey did too, albeit behind the scenes due to him not being playable as a party member.
However, what we did get to see of Riku being playable in the party, being his Limit technique with Sora, in which their weapons changed and altered, in a manner similar to the LS's -
that is what I consider the non-canon.
