None. This is DLC / Starters Edition for a game called Starlink made by Ubisoft. Nintendo did a crossover with this game by adding Fox as a playable character along with the rest of the Starfox team as side characters. It even has its own unique quest involving Starwolf. As far as I'm aware, it's not canon to anything, not even the game it's in.
@@Sunnycanoe87743 oh yeah i do know that lol, it's just funny to think about how it's the only star fox content we've had over the last 8 years and it's just a cameo that isn't even canonical to itself xD
