What are these Invalid Pokemon in my Ultra Sun Misc Slots?

[NyKang]

I was taking a look at my Ultra Sun save of Pokemon I wanted to send over to Violet, and I saw these three in the Misc Slots. I have zero clue where they're from; they don't have a OT; nor do they have a Met Location. 

Any idea?

Probably Poké Pelago.
