all of Tron everywhere is exactly as canon as you want it to be

fiction is fiction, and none of it is less fiction than the rest

the tron 1982 movie is canon, all of it, including the parts that contradict each other.

the novelization of 82 is also canon despite the parts that contradict the movie.

this might be because human minds cannot comprehend the digital world without perceiving it as ever-changing, like a dream. or it might be because someone made all this up.

the prologue to Betrayal is sorta-canon but it is narrated by a version of Dumont whose memories have gone all screwy for some reason

i have written fanfic that I consider tenuously canon-compliant with Legacy while being set in the Encom system and mostly unconnected to anything going on in Flynn’s grid. this fanfic is among the things that are canon to me.

Kesomon’s Ram Expanded series on Ao3 is also canon to me even though it directly conflicts with the events of my own fanfiction about Ram which is equally canon.

this is not a thing I can or will explain.
