Your friend helping you out under Professor Mirror.

My boy is underloved! He's so nice. Anyways, this is Todd Snap (I mean, it's obvious -- his name is right here, but still). If you can't tell by the image, this is SPECIFICALLY him from the New Pokemon Snap.

In this, you're long past the main story, but you've yet to complete your photodex. There's no prestablished relationship other than a friendship, which can be as close or not-close as you decide.

He's just a nice guy to hang around (just ignore his... questionable taste in fashion. He tries)

I think he's, like, the least traumatized character in all of Pokemon. Dude has a good life.
