Except for....anyone? Anyone know what went wrong here?
That's right, Nintendo requires a licensing agreement before you're allowed to sell anything based off their IP. You'll pay them either a flat fee or a percentage of sales for each item you sell that uses their IP.
There is literally a page on how to do it:

So unfortunately for whatever tracer Stephanie paid to break the copyright...they broke the copyright and Nintendo is well within their rights to sue.
To quote: " You can buy and sell fan art, as long as the copyright holder grants you permission. The sale of fan art is illegal until otherwise. You can sell original anime art however you like, but original anime art doesn’t qualify as fan art. "
