Personally, I think it's the first option. That or only one of the battles werre canon.There can be three options imo.
The character is canon and the fight is not.
Both are Canon.
The Character is not canon(unlikely).
Luxord's time manipulation was BS. No, Luxord's attacks were not used.
Also, Scar... :/
If we count luxord I think we should count Larxene too, they summoned their weapons the same -.-
