Smash-It Stan said: So there's no like, clicking on a profile to even view it? No dashboard or friends list? I dont own a switch and never touched my Wii/Wii-U that much to know. I figured after 3 consoles they would've been up to date sans the voice chat thing. Click to expand... Click to shrink...

No, there's currently no way to view a person's Switch profile from an individual game.

(Edit: Apparently you can do this in Fortnite) I believe it's possible to send a friend request to someone in certain games, but Mario Odyssey isn't one of them, because you don't actually interact with the other players (their avatar simply appears on the balloon they leave for you when you play their balloon hunt). And once you are friends with someone, there's no way to report their profile. You have to report them in a specific game, like Splatoon 2, and "abusive avatar" isn't a reporting option in any game because avatars aren't supposed to be customizable. It's not clear if Nintendo can even see the person's avatar if you were to report them for something else.
